What Causes Seasons? It’s All About the Slant! Video Instructions
In this video we use a typical classroom globe and a light bulb to show how Earth travels around the sun in its orbit and why it has seasons. We’ll look at four different cities and see how their length of day changes based on the position of Earth in its orbit and whether it’s tilted toward or away from the sun.In the Digging Deeper section we’ll look at how the shape and tilt of Earth change the concentration of the sun’s raysIn the Teacher to Teacher section I give a few tips and hints about

Moon Phases—Modeling and Understanding Lunar Geometry Video Instructions
Video instructions showing how Moon phases occur. Why can’t Earth’s shadow explain Moon phases? How does the geometry of the sun, Earth, and Moon cause lunar phases? During what phase can an eclipse occur? This simulation demonstrates how moon phases occur. Students use a white ball to represent the Moon and a lamp to represent the Sun. Holding the ball and turning to simulate the Moon’s orbit, students watch how the lit portion of the ball changes depending on its relative position. These are t

Video: How the Sun Moves Across our Sky, Southern Hemisphere Vantage Point
In this video we’ll travel to the equator and see how the sun’s path differs when viewed from here compared to the path it takes when viewed from the northern hemisphere. We’ll see how the sunrise and sunset locations are the same regardless of location, while the path the sun takes is different. Illustrations show how the length of a day on the equator remain fairly similar while the days at locations nearer the poles, vary with the seasons. This video builds upon the previous video, “How the S

Video: Stars and Constellations, A Celestial Calendar—the Zodiac
This video demonstrates an activity. By hanging pictures of the zodiac constellations around the room and placing a lamp in the center to signify the sun, you can easily show which constellations are visible at different times of the year. Earth's vantage point changes as it orbits the sun which makes the constellations seen in March quite different than those seen in September. Copies of the constellation pictures are included for use. If you prefer to have written instructions and student assi
