To start our lesson, today we focused on what it means for something to be living or non-living. The video above is of a substance called camphor. We placed this substance in a petri dish on an overhead projector to observe how reacts to water. As you can see from the video, the substance moved in a various patterns and directions. The question the students had to answer was "is this substance alive?" In addition we took sometime to categorize objects as either living, non-living, and undecided.
