Backyard Critters
Young scholars explore the characteristics of invertebrates in their backyards. They observe, describe, and classify specimens. They conclude with a "snail race."

Your Body: A Bacteria Incubator!
Pupils use string, a petri dish, water, wipes, and other materials to collect bacteria from their body. In this bacteria lesson plan, students use ingredients to collect bacteria, observe it, predict what will happen over time, and graph...

Investigating the Uses of Backyard Bacteria
Pupils discover that the answers to some of society's waste and clean-up problems may be no further than the soil beneath their feet. They perform a Gram stain on the colonies to determine some of their characteristics.

Detecting Magnetic Materials in "Martian" Soil
Students simulate some of the Pathfinder experiments by devising methods of collecting and measuring magnetic substances in pseudo-Martian soil. The efficiency of each of the methods used to collect materials is evaluated in this lesson.
