Unit 04: Earth Materials

Recommended Timeline:

25 days

Unit Descriptor:

This unit bundles guidelines that allow students to investigate earth materials and explore how they are used in our everyday world. Students observe and discuss rocks, soil, and sand using tools (i.e. hand lenses, sieves, and balances). Outdoor experiences should be provided to the students to promote exploration while making comparisons of earth materials.

According to Research
Children come to school aware that Earth's surface is composed of rocks, soils, water, and living organisms, but a closer look will help them identify many additional properties of Earth materials. By carefully observing and describing the properties of many rocks, children will begin to see that some rocks are made of a single substance, but most are made of several substances.
