Further Yeast Investigations

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.

Changing the amount of sugar

We found adding more sugar didn’t make a difference but adding more yeast made a big difference.

Still expanding!

The balloons are still getting bigger and everyone in the class is excited to see how big the balloons grow over the weekend.
