Science Experiments

Today we began two science experiments.

In one we are discovering what effect alcohol has on the growth of bacteria. We have one petri dish that has a penny, thumbtack and a paper clip that have been soaked in alcohol, and one where the items have not been soaked in alcohol. We will check on them in a week.


In the other one we are looking at why things decompose faster in some soils than in others. We put a piece of paper in each cup, and then filled each with a different kind of damp soil: humus, potting soil, dirt, and sand. We will check on them in three days, five days and a week.
