www.lerc.nasa.gov/Other_Groups/K-12/TRC/Rockets/rocket_principles.html This isn't exactly rocket science, but then again, this is where it all starts. Read all about Newton's first, second, and third laws of motion and forces and how they relate to rocketry. These basic laws rule all motion, not just rocketry. They explain why a basketball bounces, why a baseball goes so far when you hit it with a bat, and why you go over the handlebars if you run into a tree with your bike (you don't have to try the last one -- just take our word for it!). Scroll to the bottom of the page and click on rockets, where you'll find some cool experiments to help you understand the laws of motion. Our personal favorite is the balloon-powered pinwheel!
www.lerc.nasa.gov/Other_Groups/K-12/TRC/Rockets/rocket_principles.html If you've been trying to build a rocket out of stuff in the basement, forget about it. Even the youngest children can be rocket scientists at this page. Choose among several pictures and design your own spacecraft. If you have Java capability (ask your folks about this if you're not sure), you can blast your ship into the sky.
Thinking about blasting off into the wide world of model rocketry? At this site, you can learn about it, see some rockets, and explore this exciting hobby. There's basic information on small, large, and high-powered rockets and some great picture samples to give you a look at what you can do. Now that you're this far, you may want more, so plenty of links to other rocketry resources are listed. Just consider this your launch pad to model rocketry!
www.ninfinger.org/~sven/rockets/rmrfaq.toc.html Here are the answers to many questions you might have about model rocketry, including basic questions such as: How do you do it? Where do you do it? Is it dangerous? Is it legal? Or, you may be experienced in model rocketry, and your questions are more like these: Where can I find engines that are discontinued? How can I prevent body tube damage from the shock cord? Should I invest in a piston launcher? Come on in, too! This site has categorized questions and answers for every level of rocket enthusiast. Now, should we use a thermalite fuse…?
Why not try to design your own online race car? First pick your wheels. There's a no-tread variety, one with a deep tread, and one that seems to be made out of stone. Which will go faster? Now pick the rest of the car's parts and features, and see how well you do! There is a lot about the science of racing here, too, so start your engine and zoom on over. |
