Kelper's Three Laws
A flipped classroom lesson introduces astrophysics fanatics to Kepler's three laws of planetary motion. After reading about the laws of ellipses, equal areas, and harmonies, and also learning how Newton's gravitation concepts come into...
McGraw Hill
Kepler's Third Law Interactive
Common sense says that the farther a planet is from the sun, the longer the orbit. Kepler turned common sense into his third law by quantifying this relationship. Classes explore Kepler's Third Law through an interactive tutorial. They...
McGraw Hill
Kepler's Second Law Interactive
Kepler decided to think outside the box and discovered that planets orbit in elliptical patterns. An engaging activity demonstrates the elliptical orbit pattern in relationship to the area of a planet to explain Kepler's Second Law....

Journey to Mars
Why are there launch windows when traveling to outer space? Scholars explore the trajectory of traveling from one planet to another. By adjusting the departure and destination planets, as well as the launch date, they observe the ideal...
McGraw Hill
Extra Solar Planets Interactive
Studying what you can't see can be challenging. Discover how scientists use indirect measurements to prove the existence of planets and estimate their sizes. The introduction explains the symbiotic movement of planets and stars during an...
McGraw Hill
Orbital Velocity Interactive
Why does it take Pluto 90,000 days to orbit the sun, but it only takes Mercury 88 days? An interactive lesson helps pupils find a connection between the speed of orbit and distance a planet is from the sun. The simulation allows for...

Orbital Motion
Why do planets orbit the sun in ellipses when moons orbit their planet in circles? Pupils control the semi-major axis, eccentricity of the orbit, and position angle. The resulting orbital appears with the related force vectors as...
