Green Hour Challenge #11
After we choose our tree, my son and I went out to make observations and get samples. We did a rubbing of the bark, looked for acorns and leaves. The acorns were hard to find, but we did manage to find a few pieces. We noticed the moss on the oak to which my son warned me that the moss will make you itch. We measured the width of the trunk. We listened to the birds and did recognize a robin's song. We plan to go out later to make more observations and update our tree study book.
