Step 2: Clean the plastic bottle and fill it one-fourth with vinegar.
Step 3: Place the funnel in the mouth of the balloon and add one tbsp baking soda. Twist the neck of the balloon to secure the baking soda inside.
Step 4: Carefully slip the mouth of the balloon into the bottle top and untwist the balloon.
As the baking soda slips into the bottle, it reacts with vinegar kicking off a chemical reaction and realising bouts of carbon dioxide gas.
This gas rises up and inflates the balloon, bringing your jack-o-lantern to life.
23. DIY Sundial
Sundial is a great math-cum-engineering activity to do with kids. With some basic supplies and a bright sunny day, you are all set for this hands-on STEM activity.
What you will need:
- Craft paper
- Clay/ Dough
How to Make a Sundial:
Step 1: Draw a big circle on the craft paper and cut it out using scissors. This will be your dial.
Step 2: Paste the dial on the cardboard to make a firm base.
Step 3: Poke a pencil at the center of the dial and secure it using clay or dough. Make sure the pencil is upright.
Step 4: Now place this arrangement in a sunny spot where you expect the Sun to be all day long.
Step 5: Using pen and scale, mark the shadow of the pencil on the dial. Write the hour corresponding to the shadow.
Step 6: Once this is done, you have to mark the shadow corresponding to every hour on the clock. We used a timer to help us keep the track.
By the end of the day, you should have at least six markings ready. These markings can then be used to trace the other half of your sundial.
That’s it! Your Sundial is ready! Notice the gaps between the markings. Each gap signifies an hour on the Sundial.
Put your sundial at the same spot in the sun, you can make out the time by looking at the shadow of the pencil.
24. Sink or Float
Experiment with buoyancy with this simple, easy to do science activity. This sink or float science experiment for kids is a wonderful way to demonstrate how air helps in making the objects float.
What you will need:
- 2 Oranges
- Tall Glass Vessel
How to do it:
Step 1: Fill the glass vessel three-fourth with water.
Step 2: Peel an orange and drop it into the vessel. This will sink to the bottom of the flask.
Step 3: Next, put an unpeeled orange in the water flask. This orange will float.
By common logic, unpeeled orange should float, as it is lighter! But in this case, it is the lighter object that sinks! Why?
Well! There is a cool science at play here. An orange peel is porous and packs in many air pockets, which give it the necessary up-thrust to make it float.
When the orange is peeled, these air pockets are removed thus sinking a peeled orange. So cool!!
25. Leaf Chromatography
This is a simple plant science activity to do with children to pique their interest in plants.
Chromatography is a scientific technique used by chemists to separate two or more substances present in a liquid.
This science experiment for kids is an easy demonstration of colour pigments present in leaves and requires material easily available at home.
You will need:
- Kitchen Paper towel
How to do it:
Step 1: Take a leaf and grind it to make paste.
Step 2: Make a 1:1 solution of water and alcohol in a cup. Mix the leaf paste in the solution.
If you don’t have rubbing alcohol, you can use nail paint remover with increased concentration in the solution.
Step 3: Cut a long strip of kitchen paper towel with scissors.
Step 4: Roll the paper towel around the middle of the pencil so that one end of the kitchen paper towel hangs loose.
Step 5: Place the pencil across the cup so that the loose end dips into the solution. Make sure not to dip more than 3-4cms of the paper towel.
Now, let the paper towel sit still. After a few hours, you will notice different colour pigments on the paper towel strip. This happens due to alcohol and capillary action.
Rubbing alcohol breaks the colour from the leaves and dissolves it in the solution. Capillary action on the other hand is responsible for the liquid climbing up the paper towel.
You will also notice that your leaf will be almost bleached after some time because of the rubbing alcohol.
All in all, a simple yet very enlightening experiment to do with kids at home.
Engaging in such activities help children to ask questions, think beyond the obvious and observe. Exactly what learning should be like!
26. Magical Coin
This is one of the most fun and easy science experiment for kids of all ages. Take a coin and place it on a table. Put a clear plastic glass over the coin. Look at the coin from the side of the glass.
Can you see it?
Of course yes! Now fill water in the glass and try to spot the coin again from the same side. Is it still there? Ta-da!! The coin has disappeared.
27. Density Tower
This is a magical science experiment for kids where children get to stack liquids. Yes! You read it right…Liquids! The trick is using liquids of varying density.
What you will need:
- A tall glass/flask
- Dish soap
How to do it:
Step 1: Add honey to the glass till it is one-third full. Since honey is the densest among dish soap and oil, it will form the bottom layer.
Step 2: Using a syringe/pipette, carefully add dish soap above the honey. The trick is to add the liquid along the side of the glass so it gently slides down without disturbing the bottom layer.
Step 3: Finally, add oil through pipette to the liquid tower.
Owing to their different densities, these three liquids will layer above each other forming a density tower.
To add more science fun to this science experiment, we dropped a small ball into our density tower.
To children’s amazement, the ball sank below the top layer and floated above the middle layer.
28. Plant X-Ray
Turn your kids into little biologists as they investigate the plant vascular system with this plant X-Ray science experiment.
The vascular system of plants consists of conducting tissues and supporting fibers, which transport nutrients and minerals to different Parts of the Plant.
With this cool science experiment, your kids (and you!) will be able to see the vascular system in all its beauty and that too with naked eye, without any microscope.
How to do it:
What you need is cabbage leaves. That’s all! We choose red cabbage owing to its season, availability and the lovely colour.
Take the outer leaf of the cabbage and boil it in water for roughly 5-6minutes till you see the colour draining out of it.
Take the leaf out and let it cool off. Once cooled, hold it in between your fingers towards light to see the amazing vascular system of plants.
This is such an amazing science activity to see a vascular system that is otherwise hidden from the naked eyes.
You can also draw similarities between the plant’s vascular system and animal circulatory system. The web of vessels is somewhat similar.
29. Finger Piano
This cool musical science experiment for kids is just what you need to explore the science of sound while encouraging the hidden composer in your child.
You will need:
- Container Lids – Metal & Plastic
- Jenga Blocks
- Bob Pins
How to do it:
Step 1: Pull each bob pin apart so as to get a gap of 3-4” between their two ends.
Step 2: Take a plastic lid and stick the linear end of the bob pins with the sticky tape.
Step 3: Repeat step 2 with a metal lid.
Step 4: Take 3-4 jenga blocks and join them using sticky tape. Finally add bob pins to the block to make a wooden finger piano.
Strum the loose ends of the pins for musical sound.
You can adjust the distance between the respective pins to see how it influences the sound that the finger piano makes.
Also try to differentiate between the sound that emanates from metal, plastic and wooden finger piano.

30. Moon Craters
Got a space geek at home? Then this easy to do space science experiment for kids is what you need to further her curiosity and help her learn about space.
This science activity will let your child make her very own craters on the surface of the moon.
What you will need:
- A box
- All purpose flour
How to do it:
Step 1: Fill the box three-fourth with flour.
Step 2: Gently pat the box so as to level the flour.
Step 3: Drop marbles on the flour from a distance of 5-6 inches.
Lastly, gently lift the marbles to see wonderful and almost perfectly shaped craters.
31. Balancing Egg Activity
This is a fun science experiment for kids that will ensure lots of laughs and wonder. Invite your child to balance an egg on a flat surface.
Even when the surface is perfectly smooth, it is impossible to balance the egg until you bring in the magic ingredient – Salt.
Yes! That’s the magic ingredient to this trick of balancing an egg. Put some salt (a tiny heap) on the surface and try to balance the egg on the salt.
With a few trials, your egg would be standing up straight! Now, gently blow away the excess salt.
The science behind this experiment is the salt structure. Salt crystals are almost perfect cubes, thus providing the much needed support to the wobbly egg.
Have you ever wondered why your potato chip bag is almost half-filled with air? It’s really not a trick to fool you into believing that you are buying more chips.
There is actually a science behind it!
33. Magically Floating Seeds
Magically floating seeds is a great science experiment for kids and a hands-on lesson in buoyancy and how air helps things float.
With one simple ingredient from your pantry, you are all set for this cool science experiment for kids.
Take a glass of water and ask your child to add a spoonful of cumin seeds to it. The seeds will sink. Now, the challenge is to magically float the seeds.
Let the arrangement sit undisturbed for a few hours or overnight, if your child’s patience permits.
You will observe the seeds start to float and rise up in the glass. Why?
Take a closer look and you will see numerous small bubbles sticking to the seeds.
These bubbles (or air pockets) provide the seeds the upthrust to rise up. Break these air pockets by stirring the water with a spoon and the seeds will be back to the bottom.
34. Ice Fishing
Another great chemistry science experiment is ice fishing! This science activity dwells on the interaction of salt with ice and helps children practice some fun ice-fishing at the comfort of your home, all round the year!
This is no-prep, easy to set-up science experiment for kids. You just need a few things that are readily available at home:
- Flat Dish/ Plate
How to do it:
Step 1: Spread out ice on the plate and add little water.
Step 2: Lay the twine on the ice cube you want to fish out.
Step 3: Sprinkle a pinch of salt on the ice cube where it is touching the twine.
Step 4: Wait for a minute and then gently pull the twine to fish out the ice!
Salt lowers down the melting point of ice thus making ice melt around the area where it is added.
However, owing to the surrounding temperature, the water from the melted ice refreezes quickly. But this time, binding the twine within it!
Popsicle stick catapult is a no fail science activity to indulge in! Quick and easy to make, it assures lots of fun and gives children a change to observe physics in action!
36. Paper in the Bottle
This is another easy science experiment for kids that is endless fun and is great to do with friends.
Take a small piece of paper (~2”X2”) and crumble it into a ball.
Now put this crumbled paper ball on the mouth of a plastic bottle, while holding the bottle parallel to the ground.
Ask your friends to blow the paper into the bottle, without touching their mouths on the bottle. Can they do it? The paper ball will fly out instead of going inside the bottle.
37. Bending Water
Amaze your child by asking if they can bend water from a tap?
Take a balloon and inflate it. Rub the balloon on a blanket vigorously.
Now bring this balloon near the stream of water flowing through the tap (Make sure not to touch the balloon with water).
The water will bend towards the balloon. A simple but exciting Science activity for kids, indeed!
What could be more exciting than combining ordinary ingredients to make your very own slime? While we all enjoy playing with slime, making it is just as much fun!
A great lesson in chemistry and material science, this one is a must try for all kids!
Safety Rules for Science Experiments for Kids
There are a few basic safety rules that must be adhered to while performing these scientific explorations.
1. Dressing up like a chemist ensures that most of your child’s body is covered. Thus, preventing unwanted contact with materials that may cause skin irritation.
2. Always Wear Safety Glasses. This will protect your little scientist’s eyes and also make them believe they are real scientists. Thus, building up their enthusiasm to experiment and learn.
3. Always Wash yourHands. It is essential to wash hands after completing any experiment.
4. When experimenting, eating and drinking should be avoided.
5. Long hair should be properly tied away from the face.
6. It is best not to have any music playing when your little ones are experimenting, as it will hinder their ability to hear what’s happening properly.
7. Your science area (or home lab) should always be well lit and clean.
Once your child is well versed with the above safety rules, it is time to begin the science explorations.
