To demonstrate chemical energy.
What are some examples of chemical changes?
Chemical energy is a form of potential energy stored in matter when atoms join together to form chemical compounds. It can be released when matter undergoes a chemical change. The food that you eat provides your body with chemical potential energy and helps your body function. What else can chemical energy do?
- 1 liter bottle
- Plastic spoon
- 4 spoonfuls of vinegar
- 1 level spoonful of baking soda
- After putting on your goggles, carefully pour the vinegar into the bottle.
- Using the funnel, carefully pour the baking soda into the balloon.
- Without spilling any of the baking soda into the bottle, put the balloon neck around the bottle neck.
- Once the balloon is in place, lift the balloon up and shake the baking soda into the vinegar. Observe what happens. What kind of energy was released?
Now that you know how baking soda and vinegar react, make a Ziplock Bag Explosion!
