The Season Cycler (Teacher-Developed, Classroom-Tested)
We can see the seasons change, but do we know or understand why? This original product allows you to illustrate solar intensity, rotation and revolution, and angles of radiation. The markable diagram features an Earth that is tiltable in relation to the sun. Students can use the step-by-step worksheets to mark, label and rotate the Earth as they learn about the effects caused by the Earth's tilt. At the end of each activity, simply wipe the Cycler clean with a damp cloth. Developed by Jesus Garcia. Grades 8-10. Includes: 15 Season Cyclers, 15 water-based pens, Season Cycler overhead transparency and teacher's guide complete with reproducible student activity worksheets.
