Students will be able to: envision roots growing in the soil and taking in nutrients, are aware of some ways that ecologists study plant communities and help people manage land, can use visible differences in sites to predict differences in soil, know how to look for patterns in their data in order to make generalizations, can explain how soil could affect plant communities, and how living and dead plants can affect soil, are familiar with a variety of factors that together determine what plants grow where.
Day 4: Exploring Plant and Soil Connection
Students prepare for and do an outdoor investigation of soil in areas where plants and other landscape feature differ, then use their findings to think about plant and soil connections.
