Curated OER
Macromolecule Lab
During a macromolecule lab, young chemists perform multiple tests, including iodine starch tests, to determine if eight mystery foods contain lipids, sugars, or starches.

The Point is to Make ATP
Storing and transferring energy is explained here with reference to the fight or flight response, along with the need for activity in times of lowered nutrition. This is a great summary of ATP applications, and after the multiple stages...

Where Do All the Toxins Go?
Students demonstrate how chemicals accumulate in fish fat. They study path ways of toxins in the fish's body and ways to prepare fish to avoid consuming the toxins. They examine U.S. and Canada regulations to protect the environment.

Cell 5 Diffusion and Osmosis
Students distinguish between active and passive transport. Students identify key words associated with active and passive transport. They draw and explain the structure f the cellular membrane. They are able to define phospholipid...
Curated OER
Molecular Modeling
Students recognize that the fundamental building block of all organic and inorganic matter is the atom. They construct models of a sugar, fatty acid, amino acid and nucleic acid and describe their roles.
Curated OER
Levels of Organization
Students brainstorm a list of all the functions organisms carry out and how they carry them out. In groups, they are given the smallest and highest level of organization in organisms and are to fill in the missing spaces. To end the...
