Create a blog entry entitled, "Arbor Day Tree Census."
Do the following activities outside today:
Since there are no leaves yet, we won't be able to identify the trees just yet.
Figure out partners by pulling sticks.
Watch the video below to learn how to measure trees for our census.
Do the following activities outside today:
- Take pictures of the tree you are working on and of you guys doing your work.
- Use string and a marker to measure your tree diameter (DBH).
- Record your information in your Notes Spiral and be ready to write about it in a blog entry.

On another date, identify our tree types:

Reflection:
- What was the circumference at brain height (CBH) of each tree that you measured?
- Convert each circumference to diameter, by dividing by 3.14 (pi). Here is why that works.
- Based on your diameter at brain height (DBH) data, do you think the tree you measured was old and well-established, or young and newly planted? Why do you think that?
- What is the distance of your tree to the nearest man-made structure? How could that impact the growth of the tree?
- What other observations did you make?
- What species of trees did you find at Westgate?
If you finish early, watch the following video (which is very tough to understand, but so cool!).
Read about the Emerald Ash Borer beetle that is causing Arlington Heights and Mount Prospect to cut down so many of its beautiful trees!
