gravity orbit sciguide
Some of the things that I liked about this sciguide are the sites that deal with forces and Newton’s Laws. I got clarification on Newton’s 2nd Law F=ma through a cool and engaging NFL video about kicking. I got a lot of information about Newton’s 3rd Law through another NFL video, this one about kinematics, position, velocity, and acceleration. These real life (and something I’m interested in) examples got me to really understand those principles. The sciguide drove home to me the importance of Newton’s Laws as they relate to understanding gravity. Another site I liked was Park World Plot, a cool interactive site from England that makes learning about forces and friction fun. I learned about the effects of velocity and angle when it comes to orbits through a site called planet impact. I liked trying all the different settings to find out what would happen. I did not know that the comet could be broken apart by the gravity of the planet.
Right away, I am planning a lesson on weight, w=mg, and how it changes on other planets. I liked some of the interactives and simulations and want to try to incorporate them into my lesson planning. One thing that I really like about sciguides in general is the access to such a large amount of internet resources. The NFL videos are great and would make perfect additions to a discussion of Newton’s Laws, and the kids would probably never watch a football game the same way again. As we transition to common core standards I look forward to using the sciguide to try to find resources and ideas to help me meet those standards. And, as we continue to move off of the Earth, to the space station for instance, I can see a variety of topical lessons dealing with escape velocity, weightlessness, and orbit. The sciguide can help me to enhance my lessons and further my students’ understanding and curiosity.
