Today we were instructed to form a procedure and equations to figure out the amount of baking soda and vinegar needed to fill a random size plastic bag. When our class first heard the instructions, we were a bit confused and intimidated. But after some deliberation we all figured out how to make this happen. After all, everything worked out and we all passed the lab! Here are some links i used as research:

I was really worried about this lab. I did not know what was going on. But once I started working it was fairly easy.
ReplyDeleteI freaked out too! I thought it was going to be crazy and that nobody was going to pass, but it was a lot easier once we sat down and looked at the actual prompt.
