Today we did an experiment, where we put different levels of yeast and sugar in bottles to see what combinations would release the most carbon dioxide and make the balloons the biggest.
We found adding more sugar didn’t make a difference but adding more yeast made a big difference. One of the balloons popped and the wet yeast sugar went all over the window and window sill.
The balloons are still getting bigger and everyone in the class is excited to see how big the balloons grow over the weekend.
