Dear Ms. Johanson,
Today, we tried to get our cork rocket to launch. First, we put baking soda in the bottom of the plastic bottle. Then we poured lemon juice into the bottle and corked it immediately. We waited and waited and waited, but nothing happened except for a little fizzing.I'm not sure what we did wrong.
We know that lemon juice is an acid and that baking soda is a base. They should have reacted and made the cork pop the way it did during the simulation on the Kitchen Chemistry game from PBS Kids (http://pbskids.org/zoom/games/kitchenchemistry/virtual-start.html). Any advice?
Sincerely,
Carlos and Andrea

ReplyDeleteYour thought process was there. Lemon juice is an acid and baking soda is a base. The little fizzing gives you data that the two of you could use...Question...what would give a bigger fizz that would pop your cork? Think... more lemon juice? less baking soda? Have you tried vinegar and baking soda?
I might go back to the virtual simulation and see if there are measured amounts of the lemon juice and baking soda. How much of each did you use?
Vinegar is a good idea, but they should look up its pH first to see if it is a stronger acid.
