An investigation into the properties of water and states of matter is intertwined with the fall term social studies unit about explorations by sea as well as the mini-term social studies unit about the Arctic and Antarctic. In this investigation, students explore how water behaves in demonstrations and experiments. They investigate water movement, density, flotation, and buoyancy using the words flow, cargo, capacity, sink, and float. Students learn how to make predictions, make observations, record data, and draw conclusions. The water cycle is explored throughout the term as students learn about states of matter and these terms: dissolve, absorb, cohesion, viscosity, and surface tension.
Below you can find pictures of our most recent experiment: boat building to test for cargo capacity. We used tinfoil, connecting cubes, and plasticine.
