  • 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.

  5. When the vinegar solution and baking soda mix, they create an acid-base reaction, producing carbon dioxide that fills the balloon.

47. Soap boats

You will need:

  • Dish soap
  • Milk carton
  • A pair of scissors
  • Dropper

How to:

  1. Cut out little boats from the milk carton using scissors.
  2. Make a small notch in the back of the boat, right in the middle of the rear edge.
  3. Put the boat close to the edge of a sink or a container that’s filled with water.
  4. Next, use a dropper to carefully place some dish soap into the groove.
  5. As soon as the detergent comes in contact with the water, the boat will start moving forward.

48. Bouncy balls

You will need:

  • 2 tbsp. white glue
  • 1 tbsp. Cornstarch
  • Borax
  • Food coloring
  • Warm water

How to:

  1. Combine one tablespoon of borax with half a cup of water to create a solution. Stir the mixture properly until the borax fully dissolves.
  2. Next, combine the glue and cornstarch to make the bouncy ball mixture. Use a one-fourth cup to fill halfway with glue before adding one tablespoon of cornstarch.
  3. Add a few drops of food coloring to the glue/cornstarch mixture and stir lightly.
  4. Pour the glue mixture into the borax water and let it sit for 10 to 15 seconds.
  5. Remove the hardened glue mixture from the borax water with a fork and squish the gooey blob between your hands until it’s no longer sticky.
  6. Form the blob into a ball. Your bouncy ball is now ready to bounce!

49. Bending water

You will need:

  • Faucet with running water
  • Plastic comb

How to:

  1. Ask your child to brush their hair with the help of the plastic comb several times.
  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.

Frequently Asked Questions

1. What are the most important science laboratory safety rules?

Prior knowledge about the laboratory equipment is important while performing experiments. Wearing safety gear such as goggles, lab coats, gloves, and the right kind of shoes is also essential. In addition, be very careful while handling the chemicals and other liquids in the lab. Ensure children are always under adult supervision when conducting these experiments.

2. What household items can I use for science experiments?

You can use various household items for science experiments depending on the experiment you’re conducting, for example, vinegar or lemon juice work well for demonstrating acidity. If you’re exploring chemical reactions, baking soda could be ideal. And for experiments related to color theory or how liquids mix, food coloring could be an excellent choice.

3. How do science experiments help students learn?

While performing experiments, students can come up with a hypothesis, choose different variables for their experiment and come up with data. They can put their theoretical knowledge to practice, thereby enhancing their skills. Science experiments can also enhance students’ critical thinking and problem-solving abilities.

4. Why are science lessons important in early childhood?

Young children are naturally curious about the world around them and want to know how things work. To satiate their curiosity, you can encourage them to explore science facts for kids. Additionally, you can check some science shows for kids to make their learning engaging and fun. Help your child understand the essential concepts and the abilities necessary for inquiry-based learning from a young age. It will go a long way in building their cognitive skillsiThe ability of the brain that enables one to think, remember, learn, reason, read, and pay attention (1).

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).”

Science experiments for kids can keep them occupied on holiday and enhance their interest in learning science. Sink or float, sprout a bean, floating egg, ice cool, and color play are some preschoolers’ experiments. Older children can try homemade volcanoes, rock candy, edible bubbles with apples, can the plant find light, and cloud in a bottle. You may explain the science behind the experiment for a deeper understanding. Always ensure their safety and supervise while doing experiments with chemicals or tools. You may suggest age-appropriate experiments for kids to have fun while learning science.
