Is Yeast Alive? | Science Fair Projects | STEM Projects
Are the little brown grains of yeast alive? Let's find out by testing whether they can grow and use energy.

Hypothesis

The hypothesis is that yeast is a living organism.

Method & Materials

You will set up four test tubes in a test tube rack, add yeast, sugar, and water to two of the tubes, and observe the results.
You will need four test tubes, a test tube rack, warm tap water, dry yeast, and sugar.

Results

The results of the experiment suggest that yeast is a living organism, as it was able to metabolize sugar and produce a gas. The most interesting observation was that the test tubes with sugar and yeast produced a gas, while the test tubes without sugar did not.

Why do this project?

This science project is interesting because it allows us to explore the characteristics of living organisms and test whether yeast is alive.

Also Consider

Variations to consider include testing different types of sugar and testing different temperatures.
