Yesterday in Science we went to the lab and did an experiment with water and an egg to see if it would float or sink.
Today we applied that experiment to a lesson called "Sink or Float" that discussed density of objects and why things float. It also talked about regular molecules versus water molecules and what happens when water freezes. Please complete this small experiment at home tonight:
1. Fill a plastic cup or waterbotttle (preferably see-through) half full with water.
2. Mark a line on the side of the cup to show where the top of the water is
3. Place the cup in the freezer until the water is frozen.
4. Where is the top of the frozen water now? Below the original line? Above the original line? The same as the original line?
