The second experiment we did to practice making a hypothesis, carrying out an experiment, and analyzing the results was "Growing Gummy Bears." We asked the question: "What liquid will make our gummy bears grow the most?" We tried out 4 different possibilities: plain water, sugar water, vinegar water, and lemon water. We weighed and measured each gummy bear before putting them in the cup of liquid. Again, their predictions were pretty split.
When we returned to school the next day we were surprised how much they grew overnight. To avoid them becoming too mushy we took the new measurements on day 2. We found that the plain water and vinegar water grew them exactly the same. The sugar water grew the gummy bear the least. We discussed what other types of liquid could be tried if they wanted to carry this out at home!
