Step 1: Materials
8 Craft sticks
Tape and hot glue
Craft cubes (for modifications)
Plastic cups (for stackable crash targets)
Step 2: The basic frame
Step 3: Adding wheels
You may need to give some hands-on help to students who are having trouble fitting a plastic wheel into a skewer. If it is being particularly stubborn, I will use my wood cutters to whittle the end of the skewer a little so that the wheel will fit easily.
Step 4: The paperclip hook
Children in grades 1-3 sometimes have difficulty bending the paperclips. You may want to bend these as part of your prep work.
The hook should be near the front of the car, though not necessarily in the exact position that's shown. If your students add some extensive modifications that interfere with the launching, you may need to relocate the hook.
