Sixth graders conduct a variety of experiments that enable them to investigate bacteria. They use microscopes, prepared slides, video, moldy bread and pond water to observe types of bacteria and how bacteria interacts with the...

Sixth graders produce yogurt in the classroom as an example of the use of microbes in food production, and record observations in science journals.

In this lesson students will consider the characteristics and nature of yeast and molds in order to help them understand how these microorganisms affect food production.

Students discuss decomposition, bacteria, fungi and other microscopic organisms. They participate in an experiment to grow fungus on bread. As the fungus colonies grow, students observe them under a microscope to identify and locate...
