Like the black bars! More Force and Motion Fun -- Marble Races! Have I mentioned that I *LOVE* teaching science?! We discussed velocity and how objects move faster down an inclined plane set at a greater angle. We did a little experiment to prove this using our marble race track! Got the idea HERE.
FREE Science Videos~ Disney presents short, interesting science demonstrations by Bill Nye. Each clip is 1-2 minutes, loads right from the home page, and is kid-friendly! Great resource for students looking for science project ideas or for introducing new science concepts to a whole class. Sample demos include: raw egg floating in salt water, static electricity, how atmospheric pressure works, and making a periscope. Fun, fast, and free!
