• Help your child cut the orange into wedges or slices using a kids’ knife.
• Coat an orange slice or wedge with baking soda using a spoon.
• Put some orange juice in a glass or bowl, and ask the child to put the baking soda-coated orange slice into the orange juice.
• Let the child enjoy watching the orange juice fizz and bubble.

Science: The fizzing and bubbling of the orange juice result from a chemical interaction between the baking soda (base) and citric acid in the orange juice (acid).

12. Mold test

• Touch one slice of bread with unwashed hands, another with hands washed using water alone, and the final one with hands sanitized using hand sanitizer.
• Place each bread slice in a separate zip-lock bag and seal them. Encourage your child to observe the bags daily and note any changes, particularly the growth of mold.
• Ask your child to label the ziplock bags to distinguish between the slices of bread touched by unwashed hands, washed hands, and sanitized hands.
• As mold begins to grow, discuss the observations with your child.

Science: Bread mold thrives in a moist environment and feeds on the starches and sugars present in the bread. By leaving the bread slices in sealed bags, we create a mini-ecosystem perfect for mold growth.

13. Ink man

• Draw a stick figure or any shape of your choice on a tray using a marker.
• Carefully help your child pour water into the tray until it covers the drawn figure.
• Observe as the ink character floats on the surface of the water, creating a visually captivating display your child will enjoy.

Science: When ink is introduced into water, it does not dissolve or break down due to its insoluble nature. Instead, it remains suspended within the water, giving rise to a buoyant effect where the ink appears to float within the water.

14. Leak-proof bag

Image: Midjourney

• Ask your child to fill a ziplock bag with water and ensure it is securely sealed.
• Help your child gently push a sharp pencil through the bag, noting how the water doesn’t leak.
• You may let the child insert a couple more sharp pencils into the bag and enjoy the magic.

Science: The plastic bag’s polymer chains stretch and seal around the pencils, demonstrating the properties of polymers and preventing water from leaking.

15. Floating colors

• Combine cold water with blue coloring in one cup and warm water with red coloring in another.
• Fill a container with room-temperature water.
• Pour the cups of colored water into opposite ends of the container with room-temperature water.
• Encourage your child to notice how the red coloring floats while the blue coloring sinks.

Science: This phenomenon is driven by the variation in density between warm and room-temperature water, as warm water is lighter and cold water is denser. As the colder water heats up, it rises, while the warmer water cools and sinks, a process referred to as convection.

16. Rainbow towel

Image: Shutterstock

• Place several small cups or containers in a row, and fill each cup halfway with water.
• Add a few drops of different food coloring to each cup, creating a variety of colors.
• Cut a paper towel into strips that are long enough to reach from one cup to the next.
• Place one end of a paper towel strip into a cup containing colored water, and the opposite end into the next cup. Continue this with all cups, connecting them with the paper towel strips.
• Observe as the colored water travels up the paper towel strips and meets in the middle, forming a rainbow effect.

Science: This experiment demonstrates capillary action, a process where water moves up through a porous material due to the forces of adhesion, cohesion, and surface tension.

17. Static comb

• Cut colored paper into small pieces and spread them out on a table.
• Make your child hold a plastic comb over the paper pieces. Make them note that there’s no movement.
• Now, instruct the child to rub the comb against their hair multiple times to charge it.
• Ask them to hold the comb over the paper pieces and observe how they move and stick to the comb.

Science: Friction from rubbing the comb against hair creates an electron transfer, resulting in a static charge that attracts the paper pieces to the comb.

18. Dancing rice

• Pour a cup of water into a clean, transparent container. Add a teaspoon of baking soda to the water and stir until it is fully dissolved.
• Ask your child to sprinkle rice into the solution and observe it sinking due to its density.
• Now, add a teaspoon of vinegar to the mixture.
• After a few minutes, the rice will begin to move and dance in the container.

Science: The carbon dioxide bubbles form as the vinegar reacts with the baking soda. These bubbles stick to the rice and lift it to the surface. When the bubbles pop, the rice sinks back down, creating a dancing effect.

19. Egg and toothpaste

Image: Shutterstock

• Put four clean, transparent glasses on the table. Pour black coffee into two glasses and soda into the other two.
• Ask your child to coat two eggs with toothpaste, ensuring that they are completely covered.
• Put one plain egg and one toothpaste-coated egg in two separate glasses containing coffee. Place the other plain and toothpaste-coated eggs in the other glasses of coffee and soda.
• After 24 hours, you will see that the plain eggs have stained, while the ones covered with toothpaste haven’t.

Science: Toothpaste contains fluoride, which forms a shield around teeth (in this case, eggs), preventing acid erosion and staining.

20. Dry tissue in water

• Instruct your child to place a tissue at the bottom of the cup. Ensure it stays in place.
• Now, fill a clear container with water. Ensure the water level is higher than the cup’s height.
• Flip the cup upside-down and gradually push it into the water.
• Pull the cup straight out of the water and ask your child to notice that the tissue is dry.

Science: When the cup is submerged in water, the air trapped inside it creates pressure that prevents water from entering the cup.

2. Now, hold the comb near a gentle stream of water flowing from a sink faucet.
3. You will see the water bend and move towards the comb.

50. Skin and sunscreen

You will need:

• Black construction paper
• Sunscreen

How to:

1. Fold the construction paper in half to make two equal sections.
2. Apply a small quantity of sunscreen to one side of the paper and rub it in thoroughly, ensuring that only one side is covered.
3. Leave the paper in direct sunlight for most of the day.
4. Ask your child to observe that the area without sunscreen has faded, highlighting the sunscreen’s ability to protect human skin.

51. Egg drop

You will need:

• Egg
• Tape
• Cardboard
• Straw
• Sponge
• Cotton ball
• Bubble wrap
• Rubber band
• A pair of scissors

How to:

1. Select protective materials from the list and combine them to create a shield for your egg.
2. Next, carefully wrap the materials around the egg, ensuring complete protection on all sides. Secure the materials using rubber bands and tape.
3. Once you are satisfied with the egg’s armor, trim any excess materials.
4. Find a suitable space, preferably outdoors, to perform the egg drop.
5. Now, hold the egg above the chosen spot and release it.
6. After the drop, evaluate whether the egg cracked, what worked effectively, and what improvements could be made for the next attempt.

Apart from the simple experiment mentioned above, you can also try another one suggested by the blogger from Sitges, Spain who writes on the blog ‘Field Notes from Fatherhood.’ He executed a few experiments with his students and his students enjoyed them a lot. He says, “I saved the best for last – making a hot air balloon. You’ll need a piece of cardboard (I used an empty cereal box), a toaster, and a plastic garbage bag. (The thin, lightweight ones they have here in Hungary are best – the only time I’ve ever been grateful for crappy bin liners.) Wrap the box around the toaster, secure it with some tape, place the bag over it, and fire up the appliance. After a few moments you’ll notice the bag start to expand, then it will shoot right up to the ceiling. The kids thought this was pure magic, and it’s a clear example of how heated air molecules behave. We did this one over and over until I thought the toaster would melt (i).”
