A Day in Space 
Continuing with our solar system unit we will explore a website
that has charts and graphs that will teach us some differences between the
planets. Click here to
get to the site. Investigate the site
taking special notice of the following three graphs: The Mass of the Planets, Gravity on the
Planets, and A Day on Each of the Planets.
Answer the following questions using the graphs to find the answers:
