Gravity's Role in the Solar System

Gravity's Role in the Solar System is a one-page scaffolded science sheet that connects three things students usually meet separately — planets orbiting the Sun, the Moon orbiting Earth, and ocean tides — and shows that a single force explains all three. A complete answer key is included.

A five-word Word Bank supports fill-in-the-blank statements built in widening scale: the Sun's gravity holds the planets in their paths, Earth's gravity holds the Moon in its orbit, and the Moon's gravity reaches back across empty space to tug on Earth's oceans. Framing it this way makes the big idea land — gravity is not a local rule about falling objects but the force organizing the whole system.

The centerpiece is a two-panel labeling diagram. On the left, students identify the Sun, the orbit path, and a planet riding it. On the right, they identify the Moon, Earth, and the tidal bulge in Earth's oceans, seeing the pull drawn across the gap between the two bodies.

An exit question checks the counterfactual that reveals real understanding: without gravity, planets would drift away into space.

What's included: 1 student page (PDF) plus 1 answer key. Great for introducing orbits, review, or sub plans.
