Forensic Entomology: What the Blowfly Saw
Students read a paragraph describing various insects and decomposition rates, then fill in the table indicating when the three insects arrived or left the body. They write paragraphs explaining when the person died, and how they know.
Curated OER
Down the Drain
Young scholars explore what problems might occur if oxygen decreases in a body of water. They model what happens in a situation where decomposition is occurring. Students obtain, organize, graph, and interpret information. They i...

Eyes on Dissolved Oxygen
Learn about the factors that affect the way oxygen dissolves in salt water with a chemistry lab. After studying the molecular structure of water, young scientists figure out how aeration, temperature, and organic waste affect dissolved...
Curated OER
Yeast Power!
Students examine how not all microorganisms are bad and that some can actually be beneficial. In this yeast lesson students complete an experiment with yeast and answer questions.
Curated OER
Down the Drain
Young scholars examine the following concepts: If water supplies contain materials which rot or decompose, oxygen is used. Decay and decomposition require vast supplies of oxygen. The use of oxygen for decay of wastes may be a life or...
