Hands-on Activity

It's a Gas!

Fun Forces
In this activity, students will produce different chemical reactions with yeast. They will observe and measure how balloons inflate during this chemical reaction. They will then create a chart to track their observations and develop hypotheses to explain the reactions.
Topic: Chemical reactions between yeast and sugar
Real World Science Topics:
  • An exploration of simple chemical reactions.
  • An exploration of single-celled organisms.
Students will gain an understanding of the ways yeast, a single-celled organism, feeds on sugar and produces a chemical reaction.

Activity Difficulty Rating: 2 Each hands-on science activity has been ranked based on difficulty of set up and how difficult they are to perform. The rating scale is from 1 to 5, with 1 being the easiest and 5 being the most complicated.
