Real-World Math Problems? Try Google Earth!
One of the most common questions math teachers hear from their students is, “why does this matter?” They are constantly trying to convince students that math is useful and could help them in their everyday lives. But it can be a tough sell.
Pulley Calculator. RPM, Belt Length, Speed, Animated Diagrams
Pulley Calculator - Centers - RPM - Belt Length and Speed Enter any 3 known values to calculate the 4th If you know any 3 values (Pulley sizes or RPM) and need to calculate the 4th, enter the 3 known values and hit Calculate to find the missing value. For example, if your small pulley is 80mm diameter, and spins at 1000 RPM, and you need to find the second pulley size to spin it at 400 RPM, Enter Pulley1 80, Pulley 1 RPM 1000, Pulley 2 RPM 400, and hit Calculate to find the second pulley diameter.
CamScanner- A Great App for Scannig, Editing and Sharing Docs

Using your phone or tablet camera, you can take a photo and CamScanner will automatically enhance the scanned results so you can easily email, print, fax or share them in PDF or PNG format.
HyperPhysics Concepts
About HyperPhysics Rationale for Development HyperPhysics is an exploration environment for concepts in physics which employs concept maps and other linking strategies to facilitate smooth navigation. For the most part, it is laid out in small segments or "cards", true to its original development in HyperCard. The entire environment is interconnected with thousands of links, reminiscent of a neural network. The bottom bar of each card contains links to major concept maps for divisions of physics, plus a "go back" feature to allow you to retrace the path of an exploration.
Bending Light - Index of Refraction, Light, Snell's Law - PhET
Topics Snell's Law Refraction Reflection Optics Prisms Lenses Light Description Explore bending of light between two media with different indices of refraction. See how changing from air to water to glass changes the bending angle. Play with prisms of different shapes and make rainbows.
