Astronomy is science that will challenge your imagination. How many stars in a galaxy? How many galaxies in the known universe? How many strange worlds are out there on other planets, orbiting other stars, and what are they like? Is there life on planets besides Earth? The distances are mind-boggling; the numbers are immense.

Lesson Plan Grade: 6th-8th
This hands-on science lesson will help your students get a more accurate view of the solar system by making a scale model. They will do the calculations, make model planets, and find out where to place them so their model reflects reality. Seeing the relative size of the eight planets and their distance from the Sun displayed before them will allow your students to grasp the structure and vastness of the solar system. Read more
NGSS Performance Expectations:
  • MS-ESS1-3. Analyze and interpret data to determine scale properties of objects in the solar system.
Lesson Plan Grade: 6th-8th
Why can we feel gravity pull us down towards the Earth, but not sideways towards other big objects like buildings? Why do the planets in our solar system orbit the sun instead of flying off into space? In this lesson plan your students will develop a model for gravity and use it to explore answers to these questions. Read more
NGSS Performance Expectations:
  • MS-PS2-4. Construct and present arguments using evidence to support the claim that gravitational interactions are attractive and depend on the masses of interacting objects.
  • MS-ESS1-2. Develop and use a model to describe the role of gravity in the motions within galaxies and the solar system.
