1. Gallery Walk 2/25 & 2/26 You will be conducting a gallery walk to observe the energy projects You should be taking notes on you observations, as you will be mini presenting with others later If we hear ANY comments the make fun of, degrade, or otherwise criticize someone’s project, you will be removed from this activity. This should be a respectful way to learn from each other… Also, this is a ‘gallery walk’ as in ‘art gallery’ as in keep your voices down and comments should be on task and reflective!

2. After gallery walk..Which Energy option do you think is the LEAST beneficial? 1.Solar 2.Nuclear 3.Wind 4.Ocean / tidal 5.Coal 6.Oil 7.Hybrid Cars 8.Natural Gas 9.Geothermal 10.Biomass or ethanol

3. Which Energy option do you think is the MOST beneficial? 1.Solar 2.Nuclear 3.Wind 4.Ocean / tidal 5.Coal 6.Oil 7.Hybrid Cars 8.Natural Gas 9.Geothermal 10.Biomass or ethanol

4. Grouping Meet with other people who support your energy topic. You will be compiling a mini presentation for the class to discuss pros, cons, and why this energy source is something the US should pursue. Short presentation to frame your most important thoughts!

5. After presentations… Which Energy option do you think is the MOST beneficial? 1.Solar 2.Nuclear 3.Wind 4.Ocean / tidal 5.Coal 6.Oil 7.Hybrid Cars 8.Natural Gas 9.Geothermal 10.Biomass or ethanol

6. Get your phones out for an open ended poll.. http://www.polleverywhere.com/free_text_p olls/MzY0MTc1MjUx http://www.polleverywhere.com/free_text_p olls/MzY0MTc1MjUx

7. Action: Earth pulls moon. - What is the reaction? - What is stronger – action, reaction, or same? - What Law defends your answer?

8. Action: Earth pulls moon. What is stronger – action, reaction, or same? 1.Action(Earth pulls moon) 2.Reaction (moon pulls Earth) 3.Same!

9. What law defends your answer? 1.1 st Law 2.2 nd Law 3.3 rd Law

10. Google… PHET Gravity and orbits Click the first link Run the simulation and complete the Lab Activity Sheet. This is due by the start of next class for a HW grade (10 points)

11. Choose the picture you think shows the gravity forces on the Earth and the Sun. A. B. C. D. E.

12. How would these gravity forces change if the Sun got more massive? A.Increase B.Decrease C.Stay the same

13. How would these gravity forces change if the Earth was much closer to the Sun? A.Increase B.Decrease C.Stay the same

14. How would these gravity forces change if the Earth got much less massive? A.Increase B.Decrease C.Stay the same

15. How would these gravity forces change if the Earth and Sun were moved farther apart? A.Increase B.Decrease C.Stay the same

16. Choose the picture of how the Earth would move if you “turned off” the gravity forces. A. B. C. D. E.
