Notes: Terrestrial (Inner) vs. Jovian (Outer) Planets

Grouped planets based on chemical and physical properties

Terrestrial: include Mercury, Venus, Earth & Mars ◦Small, dense, rocky

Jovian: include Jupiter, Saturn, Uranus and Neptune◦Large, low density, gaseous

Quick WriteUnderneath your table, take 2

min. to summarize the main differences between terrestrial and jovian planets

Based on this information, do we need to change our predictions from yesterday?

Quiz-N-TradeEach person will receive a fact

Take 2 min. to write down the answer to your question, using your notes

Take a notebook/whiteboard with you and quiz people around the room
