Foldable

The cookie represents a rock.

Blow on the cookie with your straw for 1 minute.

The air you are blowing through the straw represents the wind weathering the rock.

Fill in the 1st box on your observation log.

Weathering from Plants and Animals

Use the toothpick to break up the cookie for 1 minute.

The toothpick is like plants and animals weathering the rock.

Fill in the 2nd box on your observation log.

Erosion by Wind

Use your straw to blow the cookie crumbs into a pile.

The movement of the weathered, broken pieces from wind is EROSION.

Weathering from Water

Now, use your syringe to slowly drop water onto the cookie for 1 minute.

The water represents the rain weathering the rock.

Fill in the 3rd box on your observation log.

Erosion by Water

Continue adding water until some of the crumbs move. The movement of weathered, broken pieces from water is also EROSION.
