Curated OER
Digestive System
In this digestive system activity, students answer a list of true/ false questions. The students answer questions based on their knowledge of each process of the digestive system.
Curated OER
Protein Exploration
Twelfth graders examine protein shapes through a computer program that can be downloaded off the Internet. The program allows students to see how proteins look when viewed with X-ray crystallography.
