Enhanced Gizmos in astronomy

Five more Gizmos have been enhanced with expanded curriculum materials. These Gizmos feature the Moon (Moonrise, Moonset, and Phases), orbits (Orbital Motion - Kepler's Laws and Comparing Earth and Venus), gravity (Gravitational Force), and the stars (H-R Diagram). 

Each of these Gizmos now includes a Student Exploration sheet, Answer Key, Teacher Guide, and Vocabulary Sheet. We have now finished enhancing Earth Science Gizmos are are tackling Physical Science Gizmos next. Enjoy the new materials!
