Sixth graders had a
science experiment. We wanted to find out how yeast carries out the process of
nutrition. We used 3 empty bottles, some yeast, some warm water and some sugar.
The process we followed was:
- First, we
labeled the bottles (one with yeast and water, one with yeast and sugar and one
with yeast, water and sugar.
- Then we
filled in the three bottles.
- Next, we
put a balloon on top of each bottle.
After waiting some time….
What happened? Which balloon had inflated the most? Why? How does yeast carry
out the function of nutrition?
First we thought of a hypothesis
Then we tested our hypothesis
After waiting some hours... These are our results
