Easy at-home Science Experiments for Kids

Bring out the hidden scientist in you and transform your home into a science lab with these simple fun science experiments for kids! They come with easy-to-follow instructions and materials you can find around the house. So what are you waiting for – hours of scientific fun and games are waiting for you. Get started now!

  1. 1.       The Penny and Vinegar Cleaning Project

Clean all dull pennies with this quick science experiment for kids!

You will need:

  • Dull old pennies or coins
  • White vinegar
  • 1 teaspoon salt
  • Bowl made of any non-metallic substance



  • Pour vinegar into the bowl and stir in some salt.
  • Place 2-4 pennies inside the bowl and wait for a couple of minutes.
  • Take them out and rinse. Aren’t they as good as new!


Vinegar is an acid that reacts with the salt and removes the copper oxide that is making your pennies dull.

  1. 2.       The Mystery of the Exploding Lunch Bag

Add some zing to a dull afternoon with this explosive science experiment for kids!

You will need:

  • Zip-lock bag
  • Vinegar
  • Baking soda
  • Warm water
  • Measuring cup
  • Tissues


  • Place the bag in the kitchen sink and pour 1/4th cup warm water into it.
  • Add half a cup of vinegar to it.
  • Spread the tissue on a flat surface, put 3 teaspoons of baking soda on it and wrap it up securely.
    • Zip the bag partially and quickly put the wrapped tissue inside and close the zip completely.
    • Leave the bag in the sink and move away.
    • Watch as the bag grows bigger and finally explodes!


The vinegar and the baking soda combine to create carbon dioxide – a gas that needs a lot of space. Wrapping the baking soda in the tissue will delay but not prevent the explosion that will occur when the bag becomes too small to contain the carbon dioxide.

  1. 3.       Talk like a duck

This fun science experiment is good for a lot of laughs!

You will need:

  • A plastic straw
  • A pair of scissors


  • Press and flatten completely one end of the straw.
  • Cut the flattened end into a sharp point like the nib of a pencil.
  • Flatten the pointed end again.
  • Take a deep breath, put the flattened end into your mouth and blow hard.
  • If you’ve done your job well, you’ll be able to make silly duck noises!


Sounds are produced from vibrations. The two points of the flattened end of the straw are forced to vibrate against each other when you blow through the straw. These vibrations create the duck-like noises you are able to produce.

These cool science experiments for kids will ensure there’s never a dull moment when you’re home!
