My 3rd grader made this at school last week. All you need is: 1 black piece of construction paper, Q-tips, bottle of any craft glue, scissors, and a small piece of white paper for the face.
1. Make your face and glue it down to the black paper.
2. Cut your Q-tips to the right size for the various parts of the body.
3. Glue the Q-tips down to form the body of your skeleton.
4. Allow it all to dry for a couple of hours.
You can use this project to help learn the names of the bones.
