Unit 4:

Space and Gravity

-To the Moon

As the captain of a Lunar mission, you are responsible for designing a flight plan for a one way trip to the moon.


Essential Question:

How do things move in space?


Student Take Aways:

Lunar phases, scale of solar system, and forces exist between objects even when they do not interact.

Big Ideas:

Mass and distance affect gravity.

Vocabulary Challenge

for students in a hurry


When stars explode, they scatter all of their chemical guts

throughout the galaxy.


For the next millions of years the chemical soup cools  down and particles collide 

(electrons + protons = atoms) 

and eventually form comets, asteroids, and even

large gravitational masses.

Who's going to clean up this mess?

The explosion could also turn into a black hole, sucking in objects faster than the speed of light because of how dense the mass is...but let's not go there yet. Too scary.


How fast those star guts (elements) cool and how they are rearranged create the

diversity of minerals

and matter on our planet and in the cosmos.
