Mississippi Science E.2.10

E.2.10 is a cluster heading. These are the individual standards under it.

• E.2.10.1

  Use informational text, other media, and first-hand observations to investigate, analyze, and compare the properties of Earth materials (including rocks, soils,...

• E.2.10.2

  Conduct an investigation to identify and classify everyday objects that are resources from the Earth (e.g., drinking water, granite countertops, clay dishes, wo...

• E.2.10.3

  Use informational text and other media to summarize and communicate how Earth materials are used (e.g., soil and water to grow plants; rocks to make roads, wall...

• E.2.10.4

  Use informational text, other media, and first-hand observations to investigate and communicate the process and consequences of soil erosion.

• E.2.10.5

  With teacher guidance, investigate possible solutions to prevent or repair soil erosion.

01

What Students Need to Do

Students compare rocks, soil, sand, and water by observing their properties. They identify the Earth materials in everyday objects and sort those materials as renewable or nonrenewable. They observe how water moves soil and test a way to keep it in place.

02

What Mastery Looks Like

A student can explain that sand is used to make glass and that soil and water help plants grow. They identify wood as renewable when trees are regrown and granite as nonrenewable. They can show how water carries soil off bare ground and how a cover can slow it.

03

Common Misconceptions

Students may think glass does not come from Earth because it is made in a factory. They may call rock renewable because more rocks exist. They may think eroded soil disappears rather than moving somewhere else.

04

How to Assess It

Show pictures of a wooden chair, a granite counter, and muddy water running off bare soil. Ask students to name the chair’s and counter’s source materials, label each renewable or nonrenewable, and sketch one way to keep the soil in place.

1. 01

   Shape two soil slopes in foil pans, cover one with grass clippings, pour equal amounts of water over both, and compare the runoff.

2. 02

   Show a glass cup and wooden spoon; ask students to write their source materials and explain which can be replaced by growing more.

3. 03

   Sort picture cards of wooden chairs, granite counters, drinking water, and clay bowls; name each source and label it renewable or nonrenewable.

4. 04

   Walk the school grounds with a checklist for stone paths, wooden benches, and garden soil; note what each material is used for.

• ENV.4

  Students will demonstrate an understanding of the interdependence of human sustainability and the environment.

• E.5.10

  Students will demonstrate an understanding of the effects of human interaction with Earth and how Earth’s natural resources can be protected and conserved.

• E.K.10

  The Kindergarten version of this standard.

• ESS.4

  Students will develop an understanding of Earth’s resources and the impact of human activities.
