Make a scale model of the Solar System and learn the REAL definition of "space." Enter how big you want to the sun to be in your model (in inches). Press calculate to see how to scale. Here is an example:If you build your solar system on a roll of toilet paper, you can make the Sun about .4 inches (10 mm) across and still fit the entire solar system on the roll. A standard roll of toilet paper has about 450 sheets that are about 4.375 inches long, hence the roll is about 164 feet long. You should check your toilet paper for length. Some are longer.

It's a Wild Ride is an extended interdisciplinary project that studies roller coaster design in science, mathematics, and language arts classrooms. Students learn and apply laws of motion, linear equations, and technical reporting. As the eight week project unfolds they move from learning content-specific knowledge and skills to applying what they learn in a group design task. Ultimately students must convince the theme park to accept their group's design through persuasive presentations. Look at interactive activities under the heading "Internet Activties to Expand Roller Coaster Knowledge"

Dan Meyer, a math teacher from Santa Cruz, CA. Dan used a videos of himself doing various things to teach graphing to his algebra students.
