What's on Your Plate?
Students demonstrate the path of food in the body. In this biology activity, students conduct an experiment to determine how large the the digestive system is. They name the different organs involved in the digestive process.
Curated OER
Insect Classification
Students compare and contrast the visible structures of three insects based on photographs. They differentiate characteristics of crane flies, ants, and wasps then create a simple classification system.
Curated OER
To Smell or Not to Smell, That is the Ester
Students explain the basic concepts of polymerization. Students participate in a lab to create a crude preparation of carboxyl esterase and test its effectiveness in reducing the residual monomer in an emulsion such as paint.
Curated OER
Polymerization Experiments
Learners explain the process of polymerization. In this chemistry lesson, students produce carboxylesterase in the lab. They test its effectiveness in removing the by-product odor.
