Grade range: 1-5
Prep: Cut corks into quarters.
Setup: Set up glue guns and designate a firing area
- Demonstrate the project
- Show step-by-step how it's built
- Explain how the rubberband stores and utilizes energy
- Describe how aiming the shooter up or down will change the cork's trajectory
- Discuss safety
- Students will understand the importance of rigidity during the lecture.
- Students will improve their motor skills and will further comprehend how the cork shooter functions during construction.
- Students will experientially comprehend how the cork shooter works using the stored energy of the rubberband, as well as their spatial reasoning skills while using the cork shooter.
Step 1: Materials
6 craft sticks
3 craft cubes
Step 2: Frame and trigger
Two cubes are placed close together on one end to support the trigger. This will make more sense in the next step.
Finally, the trigger (clothespin) is glued on.
Step 3: Wrap a rubberband around the trigger
The two cubes under the clothespin prevent the frame from buckling under the tension of the wrapped rubberband.
