 There are still some people who have not turned in their 100 point project or 100 point research packet. You wont pass this 9 weeks without those!  If you skipped last Friday, you missed a quiz. If you need to make it up, it has to be before you leave for winter break, I will not let anybody make up work after we get back…especially if you missed it while skipping.

 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.

 Albedo (reflectivity)  Ice :.80 or 80% reflected  Earth:.40 or 47% reflected  Asphalt :.04 or 4% reflected  Atmosphere  Reflection, Absorption, Transmission  Greenhouse gases in the atmosphere  Distance  Inverse square law

 PHONES AWAY. We are not disciplined enough to not play on our phones.  I’m going to have to start taking points away if I see people abusing this priveledge.   If we don’t finish the video, it is on the website.  You need to finish it and turn it in first thing tomorrow.  I will not accept it when we get back from break.  If you aren’t here tomorrow – take a picture and it to me.

Intensity of radiation at planet = 1370W/m 2 X 1AU (distance: Sun to planet in AU) W/m 2 = solar constant (what we get on earth) Calculate intensity of radiation for: 1. Earth 2. Mars 3. Mercury 4. Neptune 5. Saturn 6. Pluto

 Imagine you meet someone who did not know Earth had an atmosphere or what “atmosphere” even means.  How would you explain to him or her what an atmosphere is and why it is important?

 Use the 4 articles: a planet’s temperature the importance of an atmosphere the greenhouse effect – venus, Earth and mars the inverse square law To help add to your understanding of a planet’s temperature.

We should be concerned about changes in the concentration of greenhouse gases in Earth’s atmosphere and the effects of such changes. We do not need to be concerned about changes in the concentration of greenhouse gases in Earth’s atmosphere and the effects of such changes.

 We SHOULD NOT be concerned about GHG on Earth.  Earth needs ghg to be habitable, they regulate/balance temperature  Important to other organisms (plants)  Most of our atmosphere is not ghg, and steps are being taken to reduce ghg emissions  The Earth normally goes through periods of hot and cold.  We SHOULD be concerned about GHG on Earth.  More ghg and higher temperatures than ever before  Our gh effect could spiral out of control and turn our planet into one like Venus  Temperature increases from ghg trapping energy are changing ecosystems (some catastrophically, some only a little)
