Students explore mass and volume. In this mass and volume activity, students pretend to be on a hike and have lost their way. Students must cross a river get back on track. Students must use mass, volume, surface area, density, property...

Students are introduced to the concept of surface tension, its dependence on material composition, and how it can produce uniquely shaped surfaces.

Students investigate how friction affects the movement of a block across surface areas. They test five different kinds of surfaces—smooth surface, wax paper, a paper towel, course, and fine sandpaper. They predict and record the results...

Students explore the components of a watershed and the factors that affect it. They read a topographical map and use geometry to determine the area of a watershed. Students estimate the volume of a body of water and perform runoff...

Students randomly select a planet, including Earth. They research key features of the planet including mass, volume, density, gravity, temperature, weather, geology, atmosphere, surface features, location from sun, Earth and other...

Fourth graders examine surface terrain and how plants and animals are affected by the temperatures and precipitation that elevation and terrain creates. Then students predict what type of environment plants and animals live in.
