Parachutes And Parafoils
Pupils study deceleration devices like parachutes and parafoils.
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...
