Leaf Science

When I think about fall and fall science activities, I think about the beautiful colors of the leaves on the trees. It’s wonderful to go for a walk and observe the changes that autumn brings.

Collecting Leaves: a Preschool Learning Experience

Have an adventure collecting leaves and other nature objects.  Examine textures, listen, observe, and explore!

Bring your leaf collection home and practice sorting leaves and seeds. Sorting is an important math and science skill and a precursor to classification.

Practice using a ruler with our leaf measurement activity. Observe the differences between the leaves and sort them by size. This is a lovely addition to a fall nature table.

Examine your leaves and create pictures with them. As you build your own Leaf Man, discuss the difference between the leaves – the colors, the shapes, etc.
