Spaced Out Sports Educator Guide -- Grades 5-8 Students learn the science of sports with the activities in this educator guide. The activities are applications of Newton's Laws of Motion. Among the guide's six activities students will do the following: -- Construct a CD hovercraft and apply Newton's Laws of Motion to make hovercraft work. -- Use gravity to locate the center of mass of irregular-shaped objects. -- Investigate the principle of conserving angular momentum. -- Create and play simulated microgravity sports with a balloon.

"We've put some of these projects into our Top 10 Construction Projects for Kids. Enjoy both the science and bragging rights in bringing these projects to life!"

"How to make your construction set: Get yourself a piece of sturdy cardboard. You'll want it to be stronger than a cereal box so it doesn't bend or rip easily. Now, simply cut your cardboard up into squares. Then along the edges or at the corners, cut some very narrow V-shaped slits."

"As winter approaches, it's easy to forget that parts of the planet rarely rise above the freezing mark. These icy outposts often hold vast deposits of oil, gas, and minerals. They also present challenges for cold-region engineers, such as the effect of low temperatures on construction materials or how to keep pipelines flowing. Your designers will warm up to cryogenics with this month's activity. See if any need mittens! "

"Students construct balloon-powered racing cars using a foam tray and drinking straws. They then test the cars along a measured track on the floor. At the conclusion of the activity, students submit a detailed report on their racer design and how it performed in the trials."

"Engineering and fun aren't always two things that kids naturally associate with one another, but there are hundreds of ways to make engineering, physics and design fun and challenging for kids. Here are 100 great experiments that will let kids construct, play, learn and grow, all while they study the fundamentals of engineering."

"Free Math Clipart for teachers! Over 9,960 images for algebra, geometry, trigonometry, probability, money, number sense, and more. This collection of illustrations for teachers and students consists of clipart for all levels of K-12 math classes. Included are coordinate and polar grids, graphs, number lines, clocks, patterns, flashcards, protractors, thermometers, fractions, geometric shapes & solids, angles & lines, bags of marbles, spinners, constructions, theorems & proofs, and dice. From the common place to the hard-to-find clipart, everything an educator needs for activities, assessments, and presentations can be found here."

"It is fairly simple to construct a working motor similar to Faraday's original motor that will amaze your students. Due to safety concerns, salt water is substituted for mercury."

Robotics program examines the expanding role of robotics in the exploration of space. Students will engage in activities before and after the videoconference, initially constructing simple machines, and then progressing to more complex devices. During the videoconference, participants learn about NASA's most advanced robotic systems.
