It is really interesting to learn about science!

Technicraft
Brainstorm
  • What we did
  • Things we got
Materials for science investigation:
  • 40 mls beaker
  • 30 mls beaker
  • Acetic acid(vinegar)
  • Sodium bicarbonate(baking soda)
  • Ziplock bag
Steps:
  1. Get a beaker filled with 40 mls of sodium bicarbonate, another beaker filled with 30 mls acetic acid (vinegar) and a ziplock bag. Getting another person is recommended in this experiment.


  1. Get a ziplock bag and pour in the sodium bicarbonate and make sure your partner is holding the ziplock bag and then get the acetic acid and pour in and then make sure your partner has closed the bag.


  1. Carefully shake it, inside the ziplock bag, a chemical reaction will take place.


Observations:
When the baking soda (Sodium bicarbonate) and the vinegar (acetic acid)  mixed up together it caused a chemical reaction. The reason for this was because when the sodium bicarbonate mixed up with the acetic acid it created a foam and the ziplock was filled up with carbon dioxide (CO2).


Safety:
Be careful if you try this, you should have an adult with you.

Danger!!!
