2. Study the behavior (response to a stimulus of some sort – temperature, light, food, etc.) of small, easily managed animals like aquarium fish, hermit crabs, isopods, or annelids.
3. Study the population ecology of those same small, easily managed animals placing different densities in habitats and observing their behavior, aspects of their health, etc.
4. Study the growth of plants to various environmental factors (light, soil pH, etc.)
5. Test the presence of heavy metals such as lead in water of various environmental sources (lake, link river, parking lot puddles, etc.)
6. Test the pH of soil in different environments (burned versus unburned; cultivated versus wild area, etc.)
