What you need:
- Baking Soda
- Measuring utensils
- Juice enough lemons to make at least one half of cup of lemon juice.
- Mix 4 table spoons of sugar with cold water. (Water should be the same amount of lemon juice.)
- Add 1 table spoon of baking soda.
- Stir the lemonade and baking soda
What is the science explanation?
DV: The amount of time the bubbles carbonate
Constants: Cup, amount of lemonade, type of baking soda, lemons, and measuring utensils.
Hypothesis: If I add more baking soda to the lemonade, then the amount of time the bubbles carbonate will increase.
Testable Question: How does changing the amount of baking soda added affect the bubble carbonation time?
