Topographic maps are invented and used as a means for representing landforms. They set up experiments to discover which variables influence the transfer of energy from the sun to air, water, and earth materials.
Students conduct experiments to discover the best passive solar water heater design.
Comparing Communicating Observing Students examine rocks in detail, discovering that they are made of combinations of minerals. Students examine the properties of water in its three common states solid, liquid, and gas. They discover what happens to water as it is heated, cooled, frozen, evaporated, and allowed to interact with other materials. Comparing Communicating Observing Students study the properties of rocks and soil. They group and seriate rocks on the basis of single, observable properties, learning simple ways by which earth materials can be organized.
