Description

SciPacks are self-directed online learning experiences for teachers to enhance their understanding of a particular scientific concept and its related pedagogical implications for student learning. Unlimited expert content help via email and a final assessment both facilitate and document teacher learning.

The Gravity and Orbits SciPack explores concepts related to Earth’s universal gravitation and how gravity affects the universe around us. The focus is on Standards and Benchmarks related to universal gravitation including variables that influence the amount of gravitational force and how gravity governs the motion of the solar system.

	Enjoyable SciPack
	Rebecca F (Elizabeth, WV) on November 19, 2012
	Earth and Space sciences are my weakest content areas, so I really found this SciPack very enjoyable. If you have a good foundation in these areas, you might find it too basic, but it covers all the basic concepts quite well. It would be a good refresher as well.

	very challenging..
	Brian Butera (Fairfield, CT) on October 13, 2011
	This class was extemely challenging. I felt this leacture along with the sci pack was geared more towards high school level. Some of the mathematical equations were way out of my middle schoolers range. Also, The lecture didnt neccesarily correspond to the sci pack itself. When I took the final assessment, several topics were not covered in the lecture. I learned a lot. But if you are middle school teacher, best bet is to try another seminar..

	Challenging
	Nikki T on January 29, 2011
	This was a very challenging scipack for me. It made we work extrememly hard to obtain success with the final assessment!!!

	very challenging indeed...
	Michael Petrescu (Stamford, CT) on March 11, 2012
	....but I DID it ! And the feeling of nailing it down is sooo comforting ! My problem was, though, some questions from the final assessment couldn't be answered by watching / reading the materials presented in the pack only.

	Full of Information
	Joy Agard on September 13, 2012
	The Gravity and Orbits SciPack was a great way for me to review the college level Physics class that I took nearly 12 years ago. Although I teach grade 5, this SciPack provided me with content knowledge at all grade levels. This isv aluable because it helped me understand the scope and sequence of gravity and orbits standards which in effect gives me a better idea of what students are supposed to know by grade 5, what I can review, and where I need to guide them in their knowledge of the solar system. I like that I now know how to scaffold UP, and really challenge the really bright students in my class.

	F=G (m1m2/r2)... Whew!
	Lorrie Armfield (Laurel, MD) on December 26, 2011
	Very challenging. Although presented concisely with multiple opportunities for educators/viewers to check their understanding of the concepts presented, as a middle school science educator who teaches Astronomy only four weeks out of a school year, this resource was overwhelming. Ithe videos helped to convey the topics, and the graphics were very beneficial. This resource focused more on physics than I expected. Overall, it was very informative.

	Volume Levels for Gravity Everywhere
	James Johnson (Custer City, PA) on January 2, 2013
	I was listening to the audio portion of the Gravity and Orbits SciPack and when I clicked on Figure 5.6 Interactive Video of Gravity Everywhere Bringing it All Together, it about drove me out of my chair. The volume on the interactive exercise is off the scale loud compared to the normal audio volume. Just wanted to let you know ahead of time.

	Factual Errors in Gravity and Orbits
	James Johnson (Custer City, PA) on January 2, 2013
	Gravity and Orbits SciPack Earth's Tides > Summary Previous SectionNext Section00:5200:0000:53Summary In this Science Object, we learned that there is a lot of similarity between physics in a freely falling elevator and a shuttle in Earth's orbit. Even though all objects in both of these experience Earth's gravitational forces, objects float in both. In our everyday language, the objects are weightless. The falling of the elevator and the orbiting of the shuttle do not depend on their masses. Objects in both experience the effects of microgravity. We also learned that there is a required speed of an object to go into orbit with a particular radius. This orbital speed decreases with increasing radius. Likewise, the orbital period increases with increasing radius. In the audio portion of the last section of text the speaker intones "...This orbital speed Increases with increasing radius. Also, the orbital period increases with increasing radius. " I believe the text is correct. The orbital speed DECREASES with increasing radius. Not also, but, "However" the orbital period increases with increasing radius, I believe is correct, as evidenced by the planets characteristic lower orbital speed and increased orbital period around the sun, as the radius from the Sun's center of gravity increases in radius. I think I have this right. Make sense?.
