## Comparing Slopes

Control the slope of lines passing through the origin (0, 0). Keep track of what changes when the slope becomes positive or negative, and when slope is larger or smaller than 1.

## Conflict

Learn about a story's conflict, and then identify the character who is describing the conflict of "Cinderella."

## Congruent Shapes

Find shapes that are congruent. Verify that they are congruent by making rotations, slides, and reflections.

## Constant Area

Do figures with the same area have the same perimeter? Arrange and rearrange 12 square tiles on a grid, and then measure the perimeter of each shape you create.

Use a "linkage strip" to to build quadrilaterals with different sets of lengths. Once you build a quadrilateral, see if you can deform it into a different quadrilateral with the same side lengths.

## Constructing Triangles

Use a "linkage strip" to build triangles with different side lengths. When you build a triangle, see if you can deform it into a different triangle while keeping the side lengths the same.

## Continents Over Time

You have two minutes to correctly arrange five images showing the positions of the continents during different geologic periods. Can you do it?

## Control a Haber-Bosch Ammonia Plant

Learn about the economics of operating a chemical factory as you try to optimize the process of a simulated Haber-Bosch process ammonia fertilizer plant. Try to maximize profitability by using your knowledge of chemistry to fine-tune the reaction: adjusting temperature and pressure in the reaction chamber, switching the type of catalyst, and adjusting the rate that the product (ammonia) and impurities are removed.

## Control the U.S. Debt!

Neither the president nor Congress appears to be near a solution on how to control the U.S. debt. Use this exercise to show them how to do it.

## Convergent Boundaries - Colliding Plates

What are convergent boundaries? Examine how collisions of oceanic and continental plates can create volcanoes, island arcs and earthquakes.
