Curated OER
Boy, Is That Buoyant!
Fourth graders see that salt increases the density of water and creates a condition wherein objects are more buoyant than would be expected under normal conditions. They describe the relationship between heat energy, evaporation and...
Curated OER
Evaporation
Students explain the process of evaporation using an activity that allows students to see the gradual disappearance of water.
