In this lesson about the origin of life, students will learn that under suitable conditions, life-like structures can form naturally from relatively simple materials. Students will mix a carbohydrate solution with a protein solution, adjust the pH, and view coacervates: amoeba-like objects, which change shape, flow, merge, divide, form vacuoles, release vacuole contents, and show other life-like properties. ...

This lesson plan is part of the DiscoverySchool.com lesson plan library for grades 6-8. Using research on environmental conditions of the prairie ecosystem (strong winds, hot and dry summers, cold winters, and plants and animals), students will design an imaginary animal, detailing how its physical and behavioral characteristics make it well adapted to the prairie. They will illustrate their animals ... Full description.

This activity has students inoculate an agar plate with yeast and expose it to sunlight to determine the effect of ultraviolet (UV) radiation on living organisms. Multiple plates are exposed to sunlight with individual groups assigned different exposure times. The plates are incubated, and then observed for differences in yeast growth. Class results are averaged and graphed to show percent survivors ... Full description.

This information will provide students with an opportunity to understand the ideas proposed by Jean Baptiste de Lamarck in 1809. Lamarck was an eighteenth century naturalist who came to the idea that organisms change over time. Among other things, he proposed a mechanism for cumulative change that was dependent on the needs of organisms and resulted from the use or disuse of particular body parts. ... Full description.

This site provides background information and a general description of Cyanobacteria, which are both aquatic and photosynthetic. That is, they live in the water and can manufacture their own food. The site explains the importance of these bacteria in the production of oil deposits. More important, however, is the fact that the oxygen atmosphere that we depend on was generated by numerous Cyanobacteria ... Full description.
