To end the year, third graders did a fun cross-curricular project about outer space. The project started with each student making a space vehicle out of a thin sheet of metal using tooling techniques. The second step was to create an outer space background using oil pastels. The students could draw on their knowledge from their recent study of space, or could make up their own planets. We attached the ships to the background with 3D-Os to make things look a bit 3D.
