Can you feel the weight of the world? After viewing this PowerPoint, your physics class will. They learn that because of the gravitational pull of the sun, Earth does not go flying off into space. They also learn how to use the universal law of gravitation to calculate Earth's mass and the inverse-square law to relate intensity and distance. This is a descriptive demonstration of these physics concepts for your high schoolers.
Fifth graders record at least four hypotheses concerning what happens when they drop an egg from a high spot. They record at least five observations or supporting ideas about the egg drop. Students test gravity by dropping an egg from a ladder and record their results with 100% accuracy. They complete the experiment and create a KWL chart and write an entry in their journal.
Through a series of experiments and demonstrations, fifth graders will learn about gravity. They will make predictions, drop various objects, write down their observations, and try to understand gravity through balance. This lesson seems as though it is intended for a summer or after school program. However, the experiments are sound and would compliment any lesson on gravity.
Eighth graders participate in several game like activities. The first, Planetary Orbit Race," involves two students holding a 12 meter rope. One member remains in their spot while the other races around in a circle. The rope represents gravity, the runner is a planet. The second activity, "Comet Time Trials," simulates a comets' orbit about the sun, and the third, "Weightless Ball," they simulate anti-gravity by keeping a beach ball aloft.
Students work with boxes and weights to find the center of gravity. In this simple center of gravity experiment, students find success in using weights to move the center of gravity. Students will be assessed at the end of the lesson as to how the center of gravity changes.
