AP Biology Lab Review
A seventy-two slide PowerPoint that reviews several lab explorations done in an AP Biology course. For each lab there is a description, concepts, and conclusions. Many pictures and graphics make this visually appealing, but it would not...
Curated OER
Polymerization Experiments
Students explain the process of polymerization. For this chemistry lesson, students produce carboxylesterase in the lab. They test its effectiveness in removing the by-product odor.
Curated OER
Enzymes
Students explore enzymes and what can inhibit and act as a catalyst for them. In this enzymes lesson students complete experiments on enzyme properties.
Curated OER
Carnivorous Plants
Students examine how carnivorous plants get their nutrients from animals. In this food web activity students examine how the plants attract their prey and are given many onilne sources to research.
Curated OER
Enzymes
Tenth graders test their saliva for enzyme activity. In this enzyme lesson, 10th graders conduct an experiment to test the enzymatic activity of their saliva. They relate the lack of certain digestive enzymes with alcoholism.
