After recording our class's song and doing activities about forests in Brazil and Oregon, we walked to Laurelhurst Park with meter sticks and 100 foot measuring tapes in hand. First, in groups of four (I was in Group 3 along with Abby, Janai, and Alex),we plotted one acre using the 100 foot measuring tape to get an idea of the size in our heads. We then used math (i.e. calculators) to figure out how much space in feet ______ amount of trees per acre would have between them if they were evenly spaced. Once we got the measurements, the four of us trees spaced ourselves out according to the numbers we got earlier. This gave me a chance to visualize how overpopulated many forests are.
We then picked a tree to find the height of with a four inch square piece of paper folded diagonally in half, creating a 45-45-90 degree triangle, a meter stick, and a 100 foot measuring tape. Above is a diagram of how we figured out the height of the tree. Once I recorded all the measurements, I plugged them into the tangent ratio to find the height of the tree.
Subsequent to finding the heights of trees, we walked back to Sunnyside in the rain, arriving just in time at 3:00pm.
