In Part 1 of the guide, students learn about and model natural systems that function to filter rainwater, provide habitat, reduce carbon dioxide in the atmosphere, improve soil, and produce food. In Part 2, students map a natural area and create a virtual garden that performs and models the ecological functions they have learned about.

The easiest way to calculate the PR for triangular patterns is to treat them as parallelograms, using four sprinklers instead of three. When examining the pattern as a parallelogram, you can see that two of the sprinklers are contributing less of an arc (and therefore a smaller part of their flow to the area) than the other two.
There are many varieties of soil but they are all derived from some combination of sand, silt, and clay; the relative percentages of these minerals determine the soil texture. The soil texture diagram will show you some standard combinations.

Soil texture, determined by the proportions of sand, silt, and clay, plays a crucial role in plant growth. The soil texture triangle helps categorize soil into 12 types based on these proportions. Understanding soil texture can guide optimal plant selection for different soil types. Created by Khan Academy. Questions.
