It's a great way to introduce your students to the nature of science: They'll reason from models; make predictions; gather evidence using online telescopes; and learn how to display, assess and interpret their own, authentic data. You'll find this project an excellent way to review and apply core ideas about gravity, orbits, systems, Earth's place in space, and other parts of physical science.

The Laboratory consists of five mini-labs (with two more to come), to be carried out in sequence. Each lab station has a key take-home message, highlighted in the Teacher's Guide. The Guide gives helpful suggestions for mentoring students as they work and answering their frequently-asked questions.
