the mix creates the most gas.
Hypothesis: (What do I think will happen)
I think the 3 tsp baking soda, 1/2 cup vinegar well be the most balloon size.
Materials:
- baking soda
- Warm water
- Sugar
- Yeast
- Bottle
- Balloon
- Salt
- Soda water
- Funnel
- Vinegar
Steps:
- balloon 1, we tack 1 bottle out, and we put 2 tsp yeast and 1tsp sugar in the bottle and put some warm water in, and put a balloon on the top, wait for 20 minutes.
- balloon 2, we tack 1 bottle out and put 3 tsp baking soda and 1/2 cup vinegar in the bottle and put a balloon on the top, wait for 20 minutes.
- balloon 3, we tack 1 bottle out and 3 Tsp salt, 1/2 cup soda in the bottle and put a balloon on the top, wait for 20 minutes.

Hi Jeff.
ReplyDeleteThis is very interesting and it looks like you had a lot of fun in science.
I like that you told us how much bubbles there were.
Next time tell us how much of the equipment we need.
BYE!
Hi Jeff.
ReplyDeleteI like that you told us steps you need do and you also told us what Materials we need.
Maybe next time you could writ your findings.
when I read your science post I think you will have good time when you do science.
