W.a.l.t to conduct, observe and record experiments
Hypothesis/Prediction: (What do you think will happen?)
I think it will start to fizz and explode aftar a few seconeds.
Zip lock bag
1. Put a table spoon of baking soda inside a paper towel and fold it up into a square. This is your ‘time release’ packet.
2. Pour into your plastic bag: 1/2 cup of vinegar and 1/4 cup of warm water.
3. Carefully put the time release packet into your zip lock bag without it dropping in the vinegar before you can close the bag.
4. Close the bag.
5. Give the bag a shake.
Results (What happened?)
First it started to fizz and gas started to apear. Then bubbles popped up and in a few seconceds boom it exploded.
(Was your prediction right or wrong? Why?
What did this experiment/your results tell you?)My prediction was right.This is a chemical change.
