Observe and have your child sketch what a tree branch looks like. Then lie on your back under the tree looking straight up the trunk and sketch the pattern. This is a dendritic pattern and can be found all around us. Look for a washed out bank of a hill, parking lot drainage, pictures of rivers, kidneys, lungs, blood vessels, and the nervous system. As you travel around town or go for a walk around the neighbourhood, point out a few of the tree patterns you see and prompt your child to do the same.
Here are some examples of dendritic (tree) patterns :
Let me know how your pattern observation goes and what your child notices that has tree patterns in their environment. Can you incorporate a dendritic pattern in your garden this year?
