2 - ESS2 - Earth Systems - FINAL (CJT 1-6-14)

Module: Effects of Wind and Water

DCI: ESS2.A Earth Materials and Systems – Wind and water can change the shape of the land.

DCI: ETS1.C Optimizing the Design Solution – Because there is always more than one possible solution to a problem, it is useful to compare and test designs.

PE: 2-ESS2-1 Compare multiple solutions designed to slow or prevent wind or water from changing the shape of land.

[Clarification Statement: Examples of solutions could include different designs of dikes and windbreaks to hold back wind and water, and different designs for using shrubs, grass, and trees to hold back the land.]

The basic elements of content seem to be

- THAT wind can change the shape of land

- THAT water can change the shape of land

There is no statement that students should know HOW wind and water can change the shape of land, but perhaps this is implicit. Regardless, we would want to limit questions about this anyway since the other elements focus on design solutions.

When it comes to questions of design, we probably want to avoid questions that simply talk about a single method for stopping or slowing down the effects of wind and water, but should try to ask questions about design comparisons.

Possible Question Starters:

 Show the results of a windbreak and ask to predict about a reconfiguration

Ask about optimal design of a dike (how high?)

Ask about wind breaks of different heights

Ask about how to design an investigation of design
