3.  Understand how our view of the solar system has changed over time and how discoveries made have led to our changing our view of the solar system.  Learn planetary characteristics such as number of moons, size, composition, type of atmosphere, gravity, temperature and surface features.  Understand the movement of planetary bodies.  Understand which planetary characteristics are more important than others when it relates to our understanding of other worlds.  Understand how proximity to the sun influences planets.  Understand the methods and tools scientists use to learn about other planets and moons in our solar system.  Understand the conditions needed for a habitable world and determine if there are habitable worlds in our solar system or outside the solar system.  Understand how we look for and study solar systems other than our own. 1.Complex Knowledge: demonstrations of learning that go aboveand above and beyond what was explicitly taught. 2.Knowledge: meeting the learning goals and expectations. 3.Foundational knowledge: simpler procedures, isolated details, vocabulary. 4.Limited knowledge: know very little details but working toward a higher level.

5.  Question for today  What can planetary characteristics (such as number of moons, size, composition, type of atmosphere, gravity, temperature and surface features) tell us about a planet?  Glue this into your science journal on the left hand side  We will fill this in line by line over the next few weeks

6.  Create a t-table, fill in as you read what is a planet  Next to your table, list the 4 other types of objects in our solar system as you read solar system objects Group 1 Names 1: 2: Group 2 Names 1: 2: Planets 1. 2. 3. 4. Planets 1. 2. 3. 4. Other Objects in Solar System with 1 characteristic each: 1. i. 2. i. 3. i. 4. i.

8. PLAYDOUGH  Please don’t mix colors  Please make sure it all gets back into the container STRING  Please unwind, don’t just pull it off the cardboard  No Tight Knots  Please get beads back into the cups  Please rewind the string on cardboard

9. *complete the activity to make a scale model of the solar system for size.

10.  What is the most striking difference that you see between the 2 groups of planets? (the 2 you read about earlier)  Of the groups you just made a table about, what are two characteristics that describe the group Earth belongs to? Two characteristics that describe the group Earth doesn’t belong to?  Which group does Pluto seem to belong in?
