CONES - A conifer tree has needles as its leaves. Conifers are usually evergreen, which means the needles stay on the tree all year long.
- These trees are known for the cones they make. Not all conifers are Pine trees, as some may think. So, not all cones are Pine cones.
- Cones are made up of scales attached to a center stalk. The scales help us identify what species of tree we are looking at. Pine cone scales are woody and have a rigid feel. Spruce cones have thinner scales than pine cones, which gives them a more flexible feel.
- The seeds are found In between the overlapping scales.
- Cones come in all sizes and different shapes.
ACTIVITY
Collect at least 4 species of cone on the grounds. Look under Hemlock, Norway Spruce, Eastern White Pine, Larch, Douglas Fir or other conifer trees. Remember not to pull the cones from the branches-- instead find them on the ground at the base of the cone bearing trees.
Sort them by size, smallest to largest, draw a picture
of each cone in order and label each sketch with the tree name.Set your paper up as shown below. Have fun!
On this tree walk you can find FOUR DIFFERENT SPECIES of OAK tree, scientific name for Oak: Quercus. Can you find a Northern Red Oak (rubra)- #3, #20, & #51, Scarlet Oak (coccinea) - #5 & #25, Cork Oak (suber) - #13 and Willow Oak (phellos)-# 42.
How can you tell the difference between the Oak trees? If you take a close look at the leaf shape, the acorns that fall from the tree, the tree shape, and the bark texture, you can figure out what species of oak you are trying to identify.
Northern Red Oaks and Scarlet Oaks seem similar, but their leaf shapes are different.
ACTIVITY Find a leaf from each tree and draw or trace it.Write a description of the leaves. What do the leaves have in common? How are they different?
Now, do the same thing with the acorns from each tree. Draw the acorns and write how they are alike and different.
Can you find a Northern Red Oak and the Willow Oak tree? They are a bit easier to tell apart, because...why? Do all four Oak tree species have the same overall shape when you look at the way the branches jut out?
Finally, compare the bark of the Cork Oak tree to that of the Northern Red Oak. How would you be able to tell them apart if the trees had no tag to help you identify them? Write your description.
RING AROUND A TREE
It's easy to find the circumference of a tree if you have a tape measure! Without one, you could use your hand as a unit of measure if the tree is not very old. With the help of a few friends, you could also use your arms! Some of our older trees may require you to hold hands with your friends, stand close to the tree, make sure your arms touch the trunk, and circle the tree with your arms. How many people did it take to make an unbroken circle around the tree? Do you think you have measured the tree with the greatest circumference? Find a few more trees and measure them with your friends. Have you found the widest tree at Westfield Friends? What do YOU think is the tree with the greatest circumference on the Westfield Friends Tree Walk?
