5 Fun, Kid-Friendly Science Experiments

Due to the coronavirus, your kids are probably home quite a bit. And they might be getting a little stir crazy—and who isn’t! But, instead of turning to trusty cartoons and tablets when they get bored, consider helping them do experiments that are not only fun, but will also teach them a little about science! The best part - all of these activities can be done with household supplies!



Oobleck


Oobleck-- a name coined by Dr. Seuss in his book, Bartholomew and the Oobleck-- is a fascinating mixture and your kids will have a blast with it. A word of warning— it can be messy, so you might want to have your kids play with it over the bowl or a tray!


What you need:

  • 2 cups cornstarch

  • 1 cup water

  • Mixing bowl

  • Food coloring (optional)

Instructions:

  1. Pour cornstarch into a mixing bowl.

  2. Slowly pour water into pour while mixing into the cornstarch. Once the mixture is thick, don’t add any more water. If the mixture is too runny, slowly add in more cornstarch.

  3. Mix in food coloring

  4. Enjoy and play!

The Science:


When your kids move their hands slowly through the mixture, it will flow through their fingers, acting like a liquid. But if they hit the mixture, it will feel hard and like a solid. A substance like this is called a non-Newtonian fluid-- similar to quicksand, its form (whether it is a liquid or a solid) depends on pressure.


Elephant Toothpaste

This fun demonstration results in an eruption of foam that bears resemblance of toothpaste large enough for elephants. Warning: hydrogen peroxide can irritate eyes, so be careful—consider wearing safety glasses.


What you need:

  • 2 tbsp. Dishwashing soap

  • Packet of yeast

  • ½ cup 3% hydrogen peroxide

  • Food coloring (optional)

  • 3 tbsp. warm water

  • Empty bottle

  • Tray or Tupperware

  • Small bowl

Instructions:

  1. Place the bottle in the middle of a tray or a large Tupperware (to avoid messes).

  2. Pour hydrogen peroxide, dishwashing soap, and food coloring into the bottle.
