Kindergarten classes continued their study of polar regions. I explained to my kindergarten scientists that an iceberg is a large piece of floating ice. I placed consecutively larger pieces of ice in a tank of water. Before I did, the children drew a picture to hypothesize what they thought the ice would look like in the water. Would it sink or float? Following this investigation, we looked at photos of real icebergs and observed that while ice floats, most of the ice is under water. Does that mean that solid ice is less dense than liquid water? As the ice melted, we watched the food coloring fall into the water.

Then we drew a path for a drop of water and placed the path in a page protector. Using friction, cohesion, and adhesion, scientists guided their drops through the path. (See previous posts for more details on this activity.)
