Recently my class did this super cool science experiment comparison lesson. We compared the chemical reaction of mixing diet coke and mentos with the chemical reaction of mixing baking soda and vinegar. Before we did each experiment I showed them the ingredients and the supplies needed for each experiment and they predicted what would happen for each experiment. After our predictions we did both science experiments, one after the other, stopping to take notes on our comparison sheets. (The comparison sheet can be found below). The class loved predicting what would happen and they loved the excitement of the reaction or “explosion” involved with both experiments even more.
Experiment #1: Diet Coke and Mentos
What you need:
1 bottle of Diet Coke
1 package of mentos
1 jar and 1 large bowl (for the diet coke spill into).
Directions:1. Put the empty jar into the bowl.
2. Fill the jar with diet coke.
3 Add mentos into the jar and watch and see what happens!
Experiment #2: Baking Soda and Vinegar
What you need:1. 1 tbsp of baking soda
3. a piece of paper towel
4. 1 jar and 1 large bowl (for the vinegar/baking soda to spill into).
Directions:1. Place one tablespoon of baking soda into a piece of paper towel and fold up the paper towel.
2. Place the jar into the bowl.
3. Fill the jar with vinegar.
4. Place the baking soda in the paper towel into the vinegar and watch what happens.
