1. Cookie Rocks - This experiment is inspired by Kinderpond's "C is for Cookie." Have all students sit around a large table. Give each kid a cookie. Then, have them destroy it!
Weathering
First, have them experiment with a toothpick. Next, give them an ice cube to see the effects of ice on a cookie. They'll use the cube to chop at the cookie. Then, hand out an eyedropper to represent rain. Kids squirt water on the cookie. Note: You could even use a spray bottle.
Erosion
Once their finished demolishing their cookie, pass out straws. Have kids blow (wind) their cookie crumbles (rock fragments) toward the center of the table. Then, sweep their crumbs into a pile.
Deposition
Add a couple drops of water to their crumbs (if needed) and squish them all together.
2. Cookie Mining Economics - Check out the Museum of Science and Industry's Cookie Mining Project. Kids excavate chocolate chips from a cookie; but, first they have to purchase the materials they need and stay within their price range!
energy resources (renewable vs. non-renewable) - You can also use this activity to explore . Kids get a soft and hard chocolate chip cookie (which represent 2 landsites). Can they dig out coal without harming the landsite? Which site was easier to retrieve the coal? Visit Third Grade Thinkers for instructions!
