2 - ESS2 Effects of Wind and Water FINAL

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.]

It's probably safe to assume that when we talk about water, we can talk about rainfall, runoff, and flowing waters in rivers.

In order to compare multiple solutions, students would have to run some sort of an investigation and then compare the results.  This is almost impossible on a multiple choice test.

We will have to stick to theoretical investigations and results.  Or, we can ask generalized questions about the design solutions. This is a second grade assessment, so language and graphics will be key. 

Possible Question Starters: 

We can have one (or possibly two) questions about the basics in the first DCI
"Which of the following is an example of a way that wind can shape the land?"

correct answer = sand dunes move from place to place in the desert

The rest of the questions should focus on design solutions.
"Students want to compare how different windbreaks can stop soil from blowing away. They use sand, a fan to make wind and bricks to make a windbreak. What else must be part of their plan?

correct answer = change the bricks and measure the sand 
wrong answers = try different kinds (amounts?) of sand, etc.
