1. Warm Up, October 9 th, 2015

2. The Water Cycle* The water cycle is the nonstop flow of water through the Earth’s hydrosphere. The water cycle is divided into four phases: evaporation, condensation, precipitation, and runoff.

3. The Water Cycle* The water cycle is the nonstop flow of water through the Earth’s hydrosphere. The water cycle is divided into four phases: evaporation, condensation, precipitation, and runoff!

4. Open System* Have no layers preventing exchange of mass or energy, anything can go in and out. Closed System* Have layers preventing the exchange of mass or energy, everything stays within it.

5. WE LEARNED EARLIER THIS YEAR THAT METEOR/ASTEROID BOMBARDMENT HELPED CREATE OUR ROCKY PLANETS CLOSEST TO THE SUN.

6. We saw how these space rocks contain ingredients necessary for life (contained water)

7. What’s the molecular formula for water?

8. NASA scientists have been able to visit our rocky neighbor Mars. This is how the first couple of rovers landed on the red rocky planet: http://www.youtube.com/watch?v=KyktvC7w7 Js http://www.youtube.com/watch?v=KyktvC7w7 Js

9. NASA scientists have been able to visit our rocky neighbor Mars. Here’s a recent shot taken by a satellite orbiting Mars. You can see the Curiosity rover landing on the planet!

11. Anyways, these rovers have taken all sorts of photos on Mars.

14. We thought we saw water on Mars here, but these are just some bluish rocks.

15. Water stays on Earth because we pretty much have a “closed” system here. Earth: “closed” systemMars: “open” system

16. Water stays on Earth because we pretty much have a “closed” system here. Earth: “closed” systemMars: “open” system Earth’s thin, layered atmosphere traps most matter here...including H 2 O.

17. Water stays on Earth because we pretty much have a “closed” system here. Earth: “closed” systemMars: “open” system Earth’s thin, layered atmosphere traps most matter here...including H 2 O. Mars’ atmosphere is skimpy and can’t hold water there.

18. Recent News! (2014) Scoop up some soil on Mars, heat it up, cool down the steam and... slurp, slurp! You've got water! (2014) Mars might appear dry as a desert, but astronauts may someday be able to tap its soil to quench their thirst. Research recently published suggests that the soil from the Martian surface contains about 2% water by weight. (2014) This is one of several insights emerging from data that the Mars rover Curiosity has been collecting. Five studies in the journal Science were published last week based on data from the rover's first 100 days on the Red Planet. (2015) Mars is confirmed to have the presence of liquid water.

19. Water Cycle – 3 Panel Comic Required: 1 Character 3 Steps of Water Cycle (minus runoff) It’s a Comic, try to have a little comedy Must be Colored on Computer Paper (looseleaf is not accepted)
