Cool Science Experiments for Kids

Here are some cool science experiments that are safe to be performed at home.

Science Fun Experiments at Home

Here are some experiments that you can do at home, along with your kids.

Tornado in a jar
This is a popular experiment among children of all ages and is pretty simple to do too.

Ingredients needed for the project: A jar, Water, A small squeeze of dish soap
Procedure: Fill the jar with water, add the squeeze of dish soap in it, close the lid of the jar and shake it and voila! You get a tornado in the jar.

 

 

Note that you can shake the jar any way in any direction. As you twist the jar, the water inside up against the glass is pulled along due to its friction again the glass walls. The fluid toward the inside takes longer to get moving. But eventually both the glass jar and the fluid are spinning as you rotate the bottle. When you stop rotating the jar, the fluid inside keeps spinning. A mini twister can be seen for just a few seconds when the outer fluid slows down and the inner fluids continue to spin rapidly. Try it again and see!

Walking water experiment
Ingredients needed for the project: Two cups, Water (you can put some color in it), Paper towel
Procedure: Take two cups and fill one of it with water and keep the other cup completely empty. You can color the water if you wish, that way the kids can see what is happening with the water and also they will love the color. Place the cup filled with water at a slight elevation. For e.g. you can place it on top of 2-3 books. Place the empty cup below the 1st cup. Now take a paper towel and insert one end in the cup filled with water and the other end should be inserted in the empty cup. Ensure that the paper towel touches the bottom of the cup. Now just wait a while and observe. You will find that the cup filled with water, placed on the top is slowly becoming empty and the cup that was empty before is slowly filling up with the colored water.

 

 

Don’t expect it to happen immediately, this experiment takes some time.

Does it dissolve?
Ingredients needed for the project: A large transparent bowl filled with water, Salt, Sugar, Rice, Flour
Procedure: The whole point of this experiment is to make children understand about ingredients that will dissolve and those that don’t. It is a simple exercise. Place a transparent bowl filled with water on a table. On a separate table place the ingredients- salt, sugar, rice, flour separately in small bowls. Now ask each child to put a spoon of each ingredient into the transparent bowl of water to see if the ingredient dissolves in it.

 

 

Ask the child to draw their own observation and conclusions. You can change the ingredients for each child and you may have to also change the water for each ingredient as it may become difficult to see through if all the ingredients are mixed together.

Coloring Daisies
Ingredients needed for the project: 4-5 Daisies (type of flower), Food coloring or water colors, Droppers (optional), Small cups or jars (4-5 depending on the number of daisies)
Procedure: Place one daisy each in the small jars or cups and fill the cup with a inch or slightly more of water. Using the dropper, add different colors in each jar containing the water with the daisies. Please note, add the color in the water and not on the daisies. Wait for a while and after about an hour or so you will notice the daisies changing color. As time passes by the color on the daisies will darken.

 

 

You can explain this process to the children by explaining that plants need water and take in the water and the water from the plants evaporate but the color stays because color cannot evaporate, thus leaving colored daisies.

Swirling colors
Ingredients needed for the project: Milk, Tray or shallow bowl, Food coloring, Cotton swabs, Liquid dish soap
Procedure: With this experiment you could show how different ingredients react when put together. So, you need to put some milk into a tray and add several drops of food coloring (use 2-3 different colors) in it. Now take the cotton swab and just dip it in the milk and use the same swab and dip it in the liquid soap after which you will have to dip it back in the milk tray. Don’t stir, just dip it and hold it still. You will find the colors swirling around. It is a great chemistry experiment and the kids enjoy the swirl of colors.

 

 

Coin Experiments that Explain Scientific Concepts

Coins can be used to demonstrate various science concepts and principles using simple experiments. Most of these experiments can be easily carried out at home and require simple things to perform.

Here are several science experiments that use coins to illustrate different concepts:

Optical Illusion Experiment

• Concepts: Refraction, light behavior
• Materials: Coin, glass, water
• Procedure: Place a coin under a glass and pour water into the glass. Observe how the coin appears to move or disappear.
• Explanation: This demonstrates refraction and how light bends when it passes through different media.

Experiment: Coin in Water

Here’s a cool experiment (its more like a trick) that you can try at home. Experiment explains useful science concepts such as Reflection and Refraction.

Reflection refers to the bouncing of light off surfaces whereas Refraction is the bending of light (due to change in speed) when passing through different media.

Setup: You need a Glass of water and a coin.

Experiment: Take one coin and place that coin inside a glass of water.

Observation: You will see them appear at two places in the glass.

Explanation: This perception is due to the principles of reflection and refraction.

Refraction of light from the coin at the water-air interface makes the coin appear a bit higher than where it is placed, and the reflection of light off the water surface to the eyes creates an additional (at times fainter) image.

This reflection and refraction of light creates multiple light paths to the eyes resulting in the appearance of two images.

I think it’s a cool trick to show to your little one!

Penny on a Card Experiment

This is a classic experiment that explains useful Physics concepts such as inertia, Newton’s First Law of Motion, and Gravity.

For the experiment, you need materials such as a Glass (Cup), a stiff card, and a small coin.

• Setup: Lay the stiff card on top of the glass (over the opening), and place the coin on top of the card.
• Experiment: Quickly remove the card using horizontal flick of your finger without providing any significant vertical force to the coin.
• Observation: When the card is flicked away, the penny drops straight down into the glass instead of moving horizontally with the card.

Explanation: Newton’s First Law of Motion states that an object stays at rest unless acted upon by an external force. Inertia is the tendency of an object to resist changes in its state of motion.

In this experiment, since the coin is not provided with a significant horizontal force when the card is flicked away, the penny stays close to its initial position. But once the card is moved away, gravitational force takes over causing the coin to fall down into the glass.

Coin Battery Experiment

You can also coins in experiments that demonstrate basics of electricity and how batteries work. Different metals have potential for creating electricity, facilitated by electrolytes that facilitate chemical reactions that produce electrical energy.

• Concepts: Electrochemistry, electrical circuits
• Materials: Copper coins, zinc washers, cardboard discs, vinegar or lemon juice, multimeter
• Procedure: Create a stack alternating between zinc washers, soaked cardboard discs, and copper coins to form a battery. Measure the voltage with a multimeter.
• Explanation: This demonstrates how batteries generate electricity through electrochemical reactions.

Coin Spinning Experiment

• Concepts: Angular momentum, physics of rotation
• Materials: Coins, flat surface
• Procedure: Spin a coin on a flat surface and observe its motion.
• Explanation: This demonstrates angular momentum and how friction eventually causes the coin to stop spinning.

Thermal Expansion Experiment

• Concepts: Thermal expansion, temperature effects on materials
• Materials: Coins, heat source (e.g., warm water, hairdryer), cold source (e.g., ice water)
• Procedure: Heat a coin and measure its diameter before and after heating, then cool it and measure again.
• Explanation: This shows how materials expand when heated and contract when cooled.

Electrostatic Experiment

• Concepts: Static electricity, charge transfer
• Materials: Coins, wool cloth
• Procedure: Rub a coin with a wool cloth to build up static charge and bring it close to small paper pieces.
• Explanation: This illustrates how static electricity is generated and how charged objects can attract neutral objects.

Pendulum Experiment

• Concepts: Periodic motion, gravity
• Materials: Coin, string, tape
• Procedure: Tape a coin to a string and create a pendulum. Measure the time it takes for several swings.
• Explanation: This demonstrates the principles of pendulum motion and how gravity affects periodic motion.

Magnetism Experiment

• Concepts: Magnetism, magnetic properties of materials
• Materials: Coins, magnet
• Procedure: Test different coins to see which ones are attracted to a magnet.
• Explanation: This shows which coins contain ferromagnetic materials and are affected by magnetic fields.

Coin Toss Probability Experiment

• Concepts: Probability, statistics
• Materials: Coins
• Procedure: Toss a coin multiple times and record the results to determine the probability of landing heads or tails.
• Explanation: This experiment helps understand the concepts of probability and randomness.

These simple experiments are easy to carry out and make it easy to understand various scientific concepts and principles, making them great for educational purposes.

Cool Science Experiments With Water

Clean Water Science Experiment

Here are some simple clean water experiments that kids can do at home and learn useful science concepts. Also find kits that will teach the importance of water conservation and recycling.

Separating insoluble solids from liquids

You can separate insoluble solids from a liquid using methods such as:

1. Sedimentation and Decantation
2. Filtration

In Sedimentation, the insoluble solids are allowed to settle down and form a layer at the bottom, known as sediments.

After Sedimentation, Decantation is carried out in which liquid is carefully poured out without disturbing the sediments at the bottom.

For example, if you take sand water in a container, you can see that the sand particles will settle down in the container after some time forming a sediment. This is the process of Sedimentation.

Then you can pour the clear water in another container without disturbing the sand at the bottom. This is Decantation.

Filtration is another process in which liquid is passed through a filtering device which filters out the insoluble solids.

To do this activity at home, you can use filter papers for filtration. Take muddy water in a container and filer it using filter paper which separates the mud from water.

The filter paper has tiny pores that allows water to pass through but does not allow mud particles to pass through.

Separating soluble solids from liquids

You can separate soluble substances from a liquid using methods such as: Distillation and Boiling.

Both these methods involves boiling, so this activity must only be performed by adults and in safe environment.

Distillation is used to separate two liquids that mix with one another. This method takes advantage of the concept that different liquids have different boiling points.

So once a liquid reaches its boiling point, it ill evaporate and separate out. Distillation is usually carried out using a special apparatus such as Liebig’s condenser.

Boling is used for separating soluble substances from a liquid, such as salt that s dissolved in water. This method uses concept such as evaporation and condensation.

You can carry out a small experiment at home to obtain salt and water from salt water.

• Add 1-2 tea spoons of saltwater in kettle.
• Heat the kettle.
• Hold a metal plate in front of the spout so that you can collect water through condensation of steam.

In some time, you can see that water gets separated and only salt is left behind in the kettle.

The Water Cycle

Water is the most important element on Earth as all living beings need water to survive. Almost 75 percent of Earth’s surface is covered with water in the form of rivers, lakes, seas, and oceans.

Main sources of water

• Rainwater – During rainy season, rainwater seeps through the soil and is stored in the underground table. This water is used by digging wells.
• Surface water – This includes different water bodies like reservoirs, rivers, streams, ponds, and lakes.
• Groundwater – this includes water bodies like wells and springs.
• Manmade sources: Bore wells, dams, canals, an tans are manmade sources of water.

Water from rivers, dams, lakes, etc. is passed to the purification plants through closed pipelines. Water is filtered here. From the purification plants, water is distributed o the houses through the network of pipes. Once it reaches our house, we store it in tanks and containers, like bottles, pots, buckets, etc.

The Water Cycle

Earth has been recycling water for over 4 billion years.

Water from the various water bodies on Earth evaporates because of the Sun’s heat (Evaporation). The water in the form of vapour then cools down at certain height and condenses to form clouds (Condensation). When too much water gets collected, the clouds become heavy and the water falls from the sky in the form of rain, snow or hail (Precipitation). The water gets collected in oceans, lakes, or ponds (Collection).

This water again gets evaporated starting the whole water cycle again.

Experiment

You can easily carry out an experiment at home to demonstrate the water cycle. You need common household items such as a large bowl, a smaller bowl/cup, a plastic wrap, water, ice cubes, a lamp (or a sunny spot).

Steps: You first need to fill the large bowl with about 2 inches of water. Place the small cup in center of the large bowl. Stretch the plastic wrap over the large bowl (it should be tightly sealed around the edges). Place some ice cubes on top of the plastic wrap, directly above the smaller cup. Place the setup in a sunny spot or under a lamp (that is powerful enough to generate heat). Leave the setup for a few hours.

Observation: The heat from the lamp will cause the water in the large bowl to evaporate. The water vapor will rise and hit the plastic cling wrap, where it cools down (condenses) due to the ice cubes and forms droplets. The droplets will gather and precipitate (drip down like rain) into the smaller bowl or cup. The collection of the water happens in the smaller bowl.

You can also demonstrate this concept by using a kettle to heat water (an adult should do this experiment as kids should not be using a kettle).

Just hold a plate with ice cubes against the spout of kettle and place an empty bowl beneath this plate to collect the water droplets.

Cloud in a Jar

We see clouds forming in the sky due to the heat in the atmosphere. You can also make a fluffy cloud in a jar and learn the science behind it.

Materials: Glass jar with a lid, 1 cup hot boiling water, blue food color (optional), Aerosol hairspray, 3-5 cubes of ice.

Note: An adult need to demonstrate this experiment (due to use of boiling water).

Steps:

• Take 1 cup boiling water. Add food coloring to make the water blue. It will help distinguish the cloud from the water and make it look like the sky.
• Pour the cup of hot boiling water into a glass jar.
• Quickly spray hairspray into the jar.
• Immediately put the lid onto the jar.
• Place 3-5 pieces of ice on top of the lid of the jar.

Observation: In sometime, you will see a cloud beginning to form in the jar, collecting below the lid. As you open the lid, you can see the cloud move out of the jar and into the air.

The warm water in the jar causes some of the water to evaporate into the air. The water vapors then rise from the surface of the water to the top of the jar.

Once it reached the top of the jar, the warm, moist air began to cool down. This is because of the ice that was on the lid of the jar.

This cooling causes the water to condense onto the particles of hairspray, forming a cloud in the jar.

Density and Buoyancy Experiment

this experiment teaches concepts such as Density, buoyancy, Archimedes’ principle.

You need materials such as coins (or stones), water, various liquids (e.g., oil, syrup).

The experiment involves dropping coins into different liquids and observing whether they float or sink.

• Explanation: This illustrates how the density of an object relative to the liquid determines whether it will float or sink.

Surface Tension Experiment

This science experiment teaches concepts such as surface tension, cohesion.

You need materials such as coins, water, dropper.

• Procedure: Use a dropper to carefully place water droplets on the surface of a coin and count how many drops fit before the water spills over.
• Explanation: This demonstrates surface tension and the cohesive forces between water molecules.

Science Concepts

Bouncing balls and the physics behind it

Understand various physics concepts related to bouncing balls, why they bounce (or do not bounce as much).

Bouncing balls make kids jump around with joy as they love to bounce brightly-colored, bouncy balls off the floor or of the walls.

These bouncy balls help develop motor skills and eye and hand coordination in children.

Bouncing balls are also great for adults to release stress.

I have seen a lot of adults use these as stress balls, at home and in office. These provide a nice distraction from work and are great for relaxing the senses.

However, you can also use these balls to teach useful science concepts to kids!

Most balls are made of rubber (or plastic). Manufacturers may use different kinds of rubber in order to provide the balls with varied bounce.

So, you can even use these balls to teach kids about Physics.

Science Concepts: Bouncing Balls

There are different kinds of bouncing balls: Tennis ball, ping pong ball, solid rubber balls, bigger sized football, basketball and volleyball.

Not all of these have the same bounce!

The degree of bounce depends on the material of the ball and the surface (they may have different elastic properties), the amount of air in the ball and other factors.

With bouncing balls, you can explain your child various Physics related concepts such as:

• Elasticity is the ability of a material to return to its original shape and size after being deformed by an external force.
• Potential energy is the energy stored in an object due to its position relative to a starting position. Common types of potential energy include gravitational, elastic, magnetic, and electric.
• Kinetic energy is the energy possessed by a body due to its motion.

What happens when you bounce a ball off a surface?

The basic concept is that energy is stored in the ball upon impact and this energy is returned during the bounce.

When you drop a ball on a surface, the elastic properties of the ball (as well as the surface) makes the ball to bounce.

On collision with the surface, the ball compresses and stores potential energy in the form of elastic deformation. This potential energy gets converted into kinetic energy when ball rebounds off the surface.

In a perfectly elastic collision, the ball would keep on bouncing back to its initial position (an infinite number of times).

In a perfectly inelastic collision, the ball would collide with surface and its motion would come to an end, with no bounce.

However, what actually happens is that with every bounce some energy is lost due to factors such as air resistance, friction within the materials, gravitational force, and deformation of the ball and surface.

As a result, the each subsequent bounce becomes shorter and eventually the ball no longer bounces.

Bouncy balls

Bright colored bouncy balls can be used indoors as well as outdoors, for birthdays and even for family gatherings.

You can even get creative with these colorful balls; you can use these to decorate your fish tank and to decorate other things around the house.

You can even use these to teach little kids to recognize the various colors.

Some of these come with a string attached that can be tied to the wrist; just through the ball and it will recoil back at you, providing you with nice catching practice.

Bouncy balls are available in various sizes; some of these balls, especially the bigger sized ones, are inflatable.

While these bouncy balls are constructed from non-toxic and environmentally friendly material, some of these may emit some chemical odor in the beginning, which usually wears of over time. You can purchase bouncy balls that have no fragrance or chemical odor.

Periodic Table

The periodic table is an important tool used in chemistry that helps understand the relationships between different elements. The table is constantly evolving as new elements are discovered.

The Periodic Table is a table in which elements are arranged in increasing order of their atomic numbers (the number of protons in the nucleus of an atom).

Dmitri Mendeleev is often credited for creating the periodic table.

Pinhole Camera: Learn how light travels

A pinhole camera is a simple device that you can use to capture images without requiring a lens. You can use it to teach basic principles of light and optics to kids.

Principles of Light

Light travels in a straight line and this is known as rectilinear propagation of light. One can see application of rectilinear propagation of light in the following:

• Pin hole camera
• Formation of Shadows
• Eclipses

Pinhole camera is a simple application of the rectilinear propagation of light. A basic pinhole camera is made up of a container with a small hole on one side and a photosensitive surface on the opposite side.

The photosensitive surface can be tracing paper, wax paper, butter paper, film or photographic paper.

In this camera, light passing through the pinhole creates an inverted image of the luminous object (which is placed outside the camera) on the photosensitive surface.

The pinhole camera was invented in the eleventh century by an Arabic scientist to view the solar eclipse without directly looking towards the sun.

You can make a pinhole camera at home and make your kids understand the basic scientific principles of light.

How to Make a Pinhole Camera?

You can make a pinhole camera at home using a cardboard box (or something similar).

This box needs to be rectangular or cylindrical and will serve as the main body of the camera.

Make a small hole near the canter of one of the faces of the box. Remove the opposite face of the box and attach a tracing paper or wax paper in its place. You may use a rubber band to secure it in place.

Your pinhole camera is now ready!

Check out digital cameras for kids.

If you place a lighted candle in front of the pin hole, an inverted picture of the candle can be seen on the tracing paper.

An inverted image is created because light from each end of the candle travels in a straight line creating an inverted image on the tracing paper.

Magnet Facts For Kids

Without magnets there would be no electric motors, computers or loudspeakers.

Magnetism is an invisible force to do with atoms – tiny particles that makeup everything. Atoms are made of even smaller particles, including electrons. Magnetism is linked to the Way that this line-up and move.

Most magnetic substances contain iron. As iron makes up a big part of the metallic substance steel, steel is also magnetic.

A magnet is a lump of iron or steel which has all its electrons and atoms lined Up. This means that their magnetic forces all add up.

• An electromagnet attracts the body of a car, which is made of iron-based steel.
• The field around a magnet affects objects which contain Iron.

The force surrounds the magnet, in a region called the magnetic field. This is strongest at the two parts of the magnet called the poles. In a bar or horseshoe magnet, the poles are at the ends.

How Planes Fly: Science Concepts

Kids love to throw toy planes in the air and watch them soar in the sky.

There are thousands of parts in an airplane. The main parts are:

• FUSELAGE – The fuselage holds the airplane structure together and houses passengers or cargo. Modern aircraft fuselage may accommodate up to 800 passengers and over 112,700 kilograms of cargo.
• COCKPIT – The cockpit holds the command and control section for controlling the airplane on the ground as well as when flying.
• ENGINES – Engines generate power and provide hydraulic and electricity. Modern aircraft use different types of engines, although jet engines are favored by most commercial airliners.
• UNDERCARRIAGE – The undercarriage, also known as landing gear, provides a platform for the aircraft to stand, also plays an important role in landing and take-off.

Here are some fundamental science concepts related to how planes fly and move through air.

Four forces of flight

The following forces affect the flight of a plane and making adjustments to these has an impact on the performance of the plane:

• Thrust: Force is something that pushes or pulls something. Thrust is the push you give to the plane (by throwing in the case of paper planes, and through the engines in a real plane)
• Lift: When the plane starts flying, air moves over and under the wings. As per Bernoulli’s principle, air over an airplane’s wing moves faster compared to the air below the wings, creating a pressure difference that provides a force called lift to the plane.
• Drag: As the plane moves through the air, the plane faces resistance from air that pushes against it trying to slow it down. This force is called drag.
• Weight: This is the force of gravity that is acting on the plane.

By having an understanding of these concepts, kids will have a better understanding of the principles that govern the movement of toy and paper planes.

So does a paper plane with larger wings will have greater horizontal displacement (will it go further)?

Well, larger surface area of the wings will help but only till a certain point.

A larger wing surface area helps generate greater lift as more air passes over the wing, and keeps the paper plane airborne longer. However, larger wings also face more drag which slows down the plane.

The ideal wing size is one where the lift and drag forces are balanced for better flight performance.

Concepts of Matter

Matter is a fundamental concept in science and forms the basis for Understanding other topics in disciplines such as chemistry and physics.

Children encounter matter such as solids, liquids, and gases in their daily lives.

Matter can also change state.

Here is an example that all kids are likely to be familiar with.

Ice (solid) changes to water (liquid) by melting. Water (liquid) changes into water vapour (gas) through vaporization.

This process is also reversible.

Water vapour (gas) changes into water (liquid) through condensation. Water (liquid) changes into ice (solid) by freezing.

Whether a substance is a solid, liquid or gas depends on: the space between the molecules, the movement of the molecules, and the forces of attraction between the molecules.

A deeper understanding of mater will help them gain a deeper understanding of the natural world.

Here are some toys that will improve your child’s understanding of matter.

There is also a fourth state of matter known as Plasma. This state is found at a very high temperature when gas occurs in the form of positive ions and free electrons.

Measurement

Measuring things such as distance, length, weight, height, temperature is a part of our daily lives.

• Buying shoe or trouser for your child? You need a measuring tape to know the length.
• Why is the school bag so heavy today? Measure its weight using a weighing scale.
• Is your child growing fast? Measure the height with a measuring tape.
• Is your child running a temperature? check it with a thermometer.

In our daily lives, we measure usually the following basic physical quantities: Length, Mass, Time and Temperature

What is Standard International (S.I.) unit?

S.I. units are a universally accepted set of unit for measuring basic physical quantities such as Length, Mass, Time and Temperature.

Measurement of length

Length is the distance between two points.

S.I. unit of Length is meter (m).

However, multiples and sub-multiples of the meter is also used for measuring length.

For example: kilometer, centimeter, millimeter.

Measurement of Mass

Mass is the quantity of matter contained in a body. Its basically the weight.

S.I. unit of Mass is kilogram (kg).

However, multiples and sub-multiples of the kilogram is also used for measuring mass.

For example: quintal, gram, milligram.

Measurement of Time

The interval between two instances is called time.

S.I. unit of Time is second (s).

However, multiples and sub-multiples of the second is also used for measuring time.

For example: minutes, hour, day, year.

Measurement of Temperature

Temperature is the measure of hotness or coldness of an object.

S.I. unit of Temperature is Kelvin (K).

Besides Kelvin, the other two more commonly used units to measure temperature are: Degree Celsius (°C) and Degree Fahrenheit (°F) .

Waste Management

Waste management is an important topic today and kids are taught in school how we all can contribute towards reducing waste.

Waste generated by humans is causing damage to Earth and deteriorating the quality of air, water and soil.

Each day massive amount of garbage is produced all over the world but unfortunately most of it is left untreated, which leads to pollution and health hazards.

That is why it is important to practice the 3Rs of Waste management – Reduce, reuse, Recycle.

• Reduce: Use only what is needed an waste less of everything.
• Reuse: Look for ways to reuse things so that waste is reduced
• Recycle: Convert waste and discarded products into new and useful products.

Types of Waste

The types of waste we generate can be categorized as biodegradable and non-biodegradable waste.

• Wastes like fruit peel, paper, wood are biodegradable as they decompose easily and mix with the soil. These cause n harm to the environment and instead make the soil fertile.
• Wastes like plastic, glass, rubber, electronic components are non-biodegradable as they do not decompose and are bad for the environment. So they need to be discarded properly.

So the next time you rush to throw any item in the trash can, think if it can be reused and put to good use.

RC Cars

There are very few things that can match the thrill of driving a radio-controlled car. You just need to put the battery properly in the car, charge the battery and you are good to go. Once the battery is fully charged, you just have to learn how to use the remote to control the car.

Someone gifted a radio controlled car to your child and it no longer works? Take it apart to understand more about its general architecture of the car. 

This knowledge should help you build your own RC car in the future. You can even reuse some parts, such as the body of the car or the radio equipment.

Safety Precautions for Science Experiments with Kids

Setting Up Your Experiment Lab

If you are planning a science experiment party for your kid and his/her friends, you’ll need items/ingredients for the experiments. Here are some common items required for Science Experiment Parties:

• Lab coats
• Safety eye goggles
• Instruction manual for each experiment
• Experiment ingredients (water/ flasks/ jars/ beakers/ test tubes etc
• Clipboards/ instruction boards
• Ingredient boards

 

 

Safety Precautions for Science Experiments with Kids

Science experiments can be a lot of fun provided they are safe and doesn’t cause any harm. Be it at a lab or at home, if you are planning on a science experiment, one of the first things you should ensure is that the experiment is not a dangerous one.

• Always supervise every experiment done by every child so that if they are doing something wrong, you can always assist them.
• Make sure that the ingredients used in the experiment are not harmful, for e.g. If you are using a food item, check if any child has any food allergies, use natural food products as far as possible which don’t harm the skin of the child, check for any sharp objects such as knives, cut glass etc that could harm a child.
• Ensure that in case of any chemicals used, the children wear proper protective gear etc. Also ensure that kids don’t put any harmful objects in their mouth.
• All experiments should be conducted in a clutter free environment so that the kids have enough space to move around and there are no breakages while doing the experiment.
• Ideally, if you intend to keep a science experiment party, try out all the experiments yourself to ensure that they are completely safe and use your discretion to decide if these experiments are child friendly.
