Learning benefits
- 💡 This activity fosters gross motor skills as children stretch and bend to mount the tubes at different heights. It introduces core STEM concepts such as gravity, slope, velocity, and momentum through trial-and-error experimentation. Working in teams enhances verbal communication, shared goal-setting, and collaborative problem-solving.
Safety notes
- ⚠️ Adult supervision is required as marbles present a choking hazard for younger siblings under 3 years old. Ensure children use blunt-nosed safety scissors and instruct them not to lean their full body weight against the drywall or glass during construction.
Cleanup
- 🧹 Peel the blue painter's tape gently off the wall at a 45-degree angle to prevent paint damage. Store the reusable cardboard tubes in a recycling bin or large box for future play, and collect all marbles in a secure container.
