We have been studying change. Well, reversible change to be specific. In our first science lab, the students independently used food color to dye water and then poured the water into ice cube trays. The trays were set outside, inside the house, in the refrigerator and in the freezer. Next class, they observed the ice cube trays and colored a sheet which helped them explain their conclusions. They had also put sea creatures into tubs of water and then next class, observed with amazement and delight that they changed- grew quite large. We took them out of the water to see if they would change again.
So that brings us to today. The children excitedly noted that the sea creatures did change - they got smaller, changing back to their original size. We re-discussed the ice cube trays and how water could change into a solid (ice) or back to water or even evaporate into the air (gas). During our movement time, we practiced being molecules. As a solid we huddled so close we couldn't move. As a liquid we held hands in a circle and moved a little bit together changing shape ever so slightly. Then we warmed up and broke apart and ran throughout the grass taking up lots of space like a gas molecule. We repeated this a few times since water has "reversible" change.
Then we lined up on one side of the yard and had a "race" across the yard. Children listened and followed directions such as forward, reverse, freeze until they all reached the other side.
During snack time, talking more about change and the concept of reverse one child mentioned we all used to be babies. I asked if we could "reverse and be a baby again?" They all laughed and one verbalized that we did not have reversible change. It was a great moment!
