Students define and identify planetary orbit, ellipse, parabola, and hyperbola, and simulate Kepler's Second Law. They explore interactive websites demonstrating orbital motion and complete modeling activities.

Students construct a solar system model. In this space science lesson, students calculate the eccentricity of a planet's orbit. They calculate the period of a planet's revolution using Kepler's formula.

Learners analyze the theories of the formation of the universe and solar system. Students analyze planetary motion and the physical laws that explain that motion: Rotation, Revolution, Apparent diurnal motions of the stars, sun, and...

Learners research the Earth's patterns of rotation and revolution, create a chart and graph of these patterns and use them to explain the causes of night and day and summer and winter.

Students construct their own pendulum. In this physics lesson, students design an experiment to find the factors affecting its period. They formulate a conclusion based on experimental data.
