Is There A Fungus Among Us?
Students experiment with fungi and yeast in order to determine their role in nature. Students study terms associated with fungi and yeast through this series of lessons.

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...

What's the Matter with My Orange?
Students use oranges to informally explore decomposition, dehydration, fermentation, the water cycle, bacteria, yeast, food webs, the needs of living things, and physical vs. chemical change over a period of three or more months.

The Effects of Heat and Acid on the Enzyme Catalase
How quickly do enzymatic reactions occur? Assist the class as they examine heat and pH change to determine the rate of chemical reactions using catalase as an enzyme. Watch them "glow" with excitement!

Forest Decomposition
Learners explore decomposition. Students define and describe components of the decomposition process. Learners make a composter in a terrarium. Students record observations and changes weekly, drawing conclusions about the results of...

Down the Drain
High schoolers 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...

Fungi
Learners examine the characteristics of fungi. In this biology lesson, students investigate the factors needed for fungi growth. They collect data and observations and write a report about them.

H2O2 Decomposition Lab I
Students conduct an experiment to determine how much hydrogen peroxide (H2O2) is actually in a store-bought solution of H2O2.
