How Gravity Powers Roller Coasters for Grade 6
A 6th-grade worksheet that uses roller coasters to explain how gravity converts potential energy into kinetic energy, with real-world problem questions that build physics vocabulary and quantitative reasoning. It opens with key terms like gravity, potential energy, kinetic energy, and friction, then applies the PE = mgh formula to a coaster's first drop. It is designed for a single science or math block or as small-group practice.
Teacher Guide & Tips
- Use this as a 40 to 50 minute lesson, starting with the key terms box so students have the vocabulary before reading the coaster scenario.
- Discussion question: Why does a roller coaster car go fastest at the bottom of the first hill rather than at the top, and where does its energy go as it climbs back up?
- Scaffold for struggling readers: Have them label each energy type on a simple diagram of a coaster hill before attempting the PE = mgh calculations, and provide a worked example with plugged-in numbers.
- Extension for advanced students: Ask them to estimate how much height a coaster would need to reach a target speed while accounting for friction, then compare their estimate to a real ride's published specifications.
- Estimated time: about 45 minutes including discussion, or 20 to 25 minutes if used as independent practice.
