Science Experiment

A few weeks ago we began an experiment for Science Week. The experiment shows the effects of germs and the importance of washing your hands. First we put an untouched piece of bread in a bag to act as our control. Next we passed a piece of bread around and had everyone touch it with their hands before they had been washed. After that, everyone washed their hands and we passed around another piece of bread for them to touch. We waited a few weeks to see what happened to the bread.

The control bread went stale and broke when the children touched it.

The clean-hand bread grew a little mold around the edges.

The dirty-hand bread grew a lot of mold and went mushy.

This is why we need to wash our hands before we eat!
