This two day activity is a fun, eye-opening, and mathematically accurate way to teach students about the scale sizes and orbits of the plants around the sun while adhering to the Next Generation Science Standards! My students are always shocked to see just how different in size and distance each planet is to one another! Ideally, it could be used within an astronomy unit after students have an understanding of the differences between the planets but can be taught at any point in the unit even as the hook. It provides students with data on the sizes of the planets as well as their distances from the sun using units that are measurable on earth.
It is aligned with the following NGSS Next Generation Science Standard Performance Expectation: MS-ESS1-3. Analyze and interpret data to determine scale properties of objects in the solar system
