Oceans

We learned about oceans this week. We conducted an experiment to see if a raw egg would float in fresh or saltwater. We discovered that it will float in saltwater because the salt water is denser than the egg and will cause it to float. The egg sank in the freshwater because the egg was denser than the water. We told addition and subtraction stories on the beach using shell pasta. We watched The Magic School Bus Takes a Dive and learned about the food chain in the ocean and how the animals depend on each other. We learned about scuba divers and the technology they use in their jobs. We made shape octopi and wrote how many sides and vertices our shape has.
