Students will create models of the different bio-molecules using gumdrops and toothpicks. They are to pick a different gumdrop color for each of their elements and then provide a key.
Dehydration Synthesis and Hydrolysis can be demonstrated by have two groups connect their molecule models and then take them back apart again.
Find pictures of the molecules on any website with the elements listed for students to use for their models.
(The preview picture has an error in the project, but it was the only one I had a picture of!)
