Needlefelting balls is a wonderful, tactile experience for the whole family. A unique way of learning geology is by felting layers in different colors to match the layers of the Earth. When the final layer is felted, you can cut it open with scissors and see the layers inside! Enjoy making these Earth spheres for your science lessons or as an Earth Day craft project!

Supplies
Wool roving, 5 colors
Needlefelting needle
Needlefelting mat
Hand carders
Scissors
Directions
1. Write the layers of the Earth on a piece of paper: inner core, outer core, inner mantle, outer mantle, crust. Assign a color for each layer.
2. Wool fiber felts easily if it is easy to draft (pull apart). If needed, use hand carders to open up the fibers.
3. Create the inner core by rolling this fiber into a ball in your hands. You can get your hands slightly wet to help the fiber felt into a little ball (sphere).
4. Add the outer core fiber over the ball. Roll in your hands. Needlefelt the ball until the entire inner core is covered with the outer core fiber color.
5. Continue in this fashion until all of the layers are felted.
Tips
Depending on the age of the children, you can make each layer match the thickness of the Earth’s actual layers to scale (e.g., the crust is very thin compared to the inner mantle). Refer to a book or online resource for a picture of the Earth’s layers.
Older children may want to select colors that represent the layers based on temperature and mineral/elemental content.
Children who are too young for using needles will love helping with the carding and rolling!
Think of an appropriate time to cut open the ball and reveal the layers. Crochet or knit a little bag for it. Make it special!
Proudly display your cut Earth ball on a nature or science table. Give as gifts for Earth Day!
