Baggie Chemistry
Objective: To observe various chemical reactions
Materials:
Ziploc Baggies
10 ml Graduated Cylinder
teaspoons
Bromothymol Blue indicator
Calcium chloride
Sodium Bicarbonate
Activity:
Explore what happens when the chemicals are mixed in baggies. You should
perform 3-5 experiments by mixing combinations of the Bromothymol Blue
indicator, Calcium Chloride, and Sodium Bicarbonate.
For example, you can mix a teaspoon of calcium chloride with 10ml of indicator.
What happens? How does this compare with the results of mixing a teaspoon of
calcium chloride with 10ml of indicator? What if a teaspoon of each solid and the
indicator are mixed? What will happen if you change the quantities?
Record what you mix (including quantities), the time involved to see a reaction,
and any other changes you may see, feel, or smell.
