Today we switched gears as we left the science fair behind for a few days and continued our work in diversity of life. Previously we had set guidelines for what makes something living or non-living. Some of these guidelines or characteristics featured movement, breathing, consuming energy, etc...
Students were asked to conduct a investigation involving secret materials (not that big of a secret). Students set up vials that contained these materials and a solution (either water, water+salt, or water+sugar). Then they made observations to help us decided whether the materials were living or non-living.
This will be a three day lab for us, we will continue observing for the next two days until we make our final conclusion.
