"NASA's Spacecraft 3D is an augmented reality (AR) application that lets you learn about and interact with a variety of spacecraft that are used to explore our solar system, study Earth, and observe the universe. Using a printed AR Target and the camera on your mobile device, you can get up close with these robotic explorers, see how they move, and learn about the engineering feats used to expand our knowledge and understanding of space. Spacecraft 3D will be updated over time to include more of the amazing spacecraft that act as our robotic eyes on the earth, the solar system and beyond! "

"Visualize in real-time the frequencies that you can hear around you and even those you cannot. The SpectrumView analyser provides a high quality real-time spectrogram and spectrum analyser display with configurable sample rate and frequency resolution for the iPhone and iPad.  You can use this application to measure the highest tones you can sing, to find the source of an annoying sound, for calibrating musical instruments or generally for all sorts of acoustic analysis.

This article will take you through the golden rules of drawing graphs, applicable to all exam boards, all situations, all the time. They are even up on my classroom wall as my 'Tips for the Top'

"The Progressive Achievement Tests in Science (PATScience) is a thoroughly researched and nationally normed test to assess student achievement in scientific understanding from Years 3 to 10. The test questions are designed to assess science knowledge, scientific literacy and understanding of scientific principles, as well as their application."

"Engage your students with open-ended science investigations and technology projects through the CREST program."

From our mobile phones to our televisions, silicon chips are a part of much of our daily lives. Where does silicon come from? Much of it comes from sand. The following video from the Chemical Heritage Foundation explains the concept of how silicon chips are created.

Great video that explains how collimating properties help in the radiator of a car.
