Earth, Moon and Sun Scale Models Mini Unit Resources
Students calculate the diameter of a basketball to determine if it would qualify for the NBA! Then, they use this information to calculate the diameter of the sun, Earth’s moon and the other planets in our solar system. Finally, students build a scale model to answer the question, “If Earth was the size of a basketball and the moon was the size of a tennis ball, how big would the sun and other plants be?” Students also have a chance to compare the mass and volume of Earth with other planets in our solar system.
