SCIENCE EXPERIMENT

Today in Science we did an experiment with micro organisms. We used sugar, bottles, yeast, cold, warm and hot water.  First we mixed 1/4 of a cup of sugar and 1/2 tsp of yeast. We tipped the sugar and yeast into the bottles. We did this to 3 bottles. After this we poured cold, warm and hot water into the bottles. We put 1/2 cup of water in.  Then we put a balloon over the tops of the bottles.

Aim:  to find out what temperature yeast needs to be active and produce a gas.

I think warm water would be best for a gas.
