This 5 part math task uses science and math standards (Great for STEM!). The students first have to analyze a food chain and then find the area of a "forest" by tiling. After that, they use the food chain scenario to determine how many of each species would be in EACH square unit of the forest. They then get different scenarios (a farmer adds more bushes to each square unit, etc.) and are asked to do the math. Finally, the students are given a food chain photograph complete with arrows and are asked to explain how living organisms obtain energy in that particular forest.
