Earth’s Systems: Processes that shape the Earth

K-2 Engineering Design

(1)	S.2.ESS.1.1	Students who demonstrate understanding can use information from several sources to provide evidence that Earth events can occur quickly or slowly.
(1)	S.2.ESS.2.1	Students who demonstrate understanding can compare multiple solutions designed to slow or prevent wind or water from changing the shape of the land.
(1)	S.2.ESS.2.2	Students who demonstrate understanding can develop a model to represent the shapes and kinds of land and bodies of water in an area.
(1)	S.2.ESS.2.3	Students who demonstrate understanding can obtain information to identify where water is found on Earth and that it can be solid or liquid.
(1)	S.K-2.ETS.1.1	Students who demonstrate understanding can ask questions, make observations, and gather information about a situation people want to change to define a simple problem that can be solved through the development of a new or improved object or tool.
(1)	S.K-2.ETS.1.2	Students who demonstrate understanding can develop a simple sketch, drawing, or physical model to illustrate how the shape of an object helps it function as needed to solve a given problem.
(1)	S.K-2.ETS.1.3	Students who demonstrate understanding can analyze data from tests of two objects designed to solve the same problem to compare the strengths and weaknesses of how each performs.

What kind of changes to the Earth’s surface happen quickly?

What kind of changes to the Earth’s surface happen slowly?

What Earth materials and systems can change the shape of the land?

How can land change over time?

How can wind or water change the land around you?

What can help to reduce or stop water and / or wind erosion from changing the shape of the land?

What are the different bodies of water and land on Earth and can you locate them on a map?

In this module students explore how the surface of the Earth is always changing. They are introduced to different kinds of maps and explore how these maps convey different kinds of information about the world we live in, including where water is found on Earth. Students investigate the different forces that shape the surface of the Earth and design solutions to limit the impact of erosion on a fictional community.
