This three dimensional model allows students to study our solar system - looking at planets' relative sizes and colors. It demonstrates why the planets are sometimes visible in the night sky and sometimes they are not.
The model features a 5.9" sun in the center, and has eight planets situated on metal bars which can be manually moved around the sun to show relative positions at various times during the year. Planets include Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus and Neptune. The sturdy base features a chart labeling each month and the location in degrees. The model stands 13" in total height, and the outer most (dwarf) planet measures 10.75" from the sun. With the planets lined up straight, the model measures 18.25" wide.
Model includes a comprehensive experiment guide that includes three activities, various topics for further exploration, a grading rubric and a planet location table.
