Description

Bridging research and practice, FOSS Third Edition Modules engage students and teachers in enduring experiences that lead to deeper understanding of science and engineering concepts, as well as the natural and designed world. The Water Module for Grade 3 provides students with experiences to explore the properties of water, changes in water, interactions between water and other earth materials, and how humans use water as a natural resource. Students will learn that water is the most important substance on Earth, dominating the surface of our planet, changing the face of the land, and defining life.

In the FOSS Third Edition Water Complete Kit with 4 hands-on investigation activities, students will: conduct surface-tension experiments; observe and explain the interaction between masses of water at different temperatures and masses of water in liquid and solid states; construct a thermometer to observe that water expands as it warms and contracts as it cools; investigate the effect of surface area and air temperature on evaporation, and the effect of temperature on condensation; investigate what happens when water is poured through two earth materials–soil and gravel; design and construct a waterwheel and use it to lift or pull objects; and use field techniques to compare how well several soils drain.
