The user can draw a compound or choose from a selection of compounds from three databases. Once a compound has been selected the user can click the 2D to 3D button to convert the molecule into a 3D model which is then displayed in the viewer, located on the right side of the screen. In addition to the 3D viewer you can also use the app to distinguish between atomic, molecular, and ionic solids by clicking on the crystallography model tab. What I love about this function of the app is that it helps users identify that each type of solid has different structures and patterns.

Great short video to explain the jump from the Bohr model to the QM model

"Students will build a lung model to learn how their lungs and diaphragm work to make them breathe. The lesson features a demonstration on how incomplete combustion of fossil fuels releases particles into the air that can negatively affect human health, and how we can protect ourselves from these effects."

"Follow these instructions to build your own International Space Station model."

Interactive "game-mode" animation for DNA Model - great for introducing and reinforcing DNA anatomy 

"See three-dimensional planet models along the way as you shuttle from Pluto at the furthest reaches of the Solar System to the Sun, which is represented by the 37-metre Anglo-Australian Telescope dome at Siding Spring Observatory.  The planets are displayed on huge billboards with the size of the planets and the distance between each billboard scaled relative to the dome - the Sun - along the five main roads that lead to Coonabarabran in regional NSW."

"A junior science class demonstrates a lesson about multicelular organisms using glove puppets with a constructivist approach to problem solving and a blended learning model. This activity has even been adapted by the teacher Roland Gesthuizen to help explore complex topics including technology issues such as cyberbullying, privacy, programming, copyright, freedom and ethical behaviour whilst improving their literacy and social skills. This is a very engaging way to quickly assess student understanding using some simple technology and computer skills without the need for sophisticated digital equipment."

Learning science and math is normally thought of as committing to memory facts and procedures. Because of this we tend to perceive the best way to teach is through rote memorization of ideas, theories, and models. As a consequence, students experience little opportunity to develop a real understanding of what they are expected learn. Our challenge is to craft strategies which allow student interactivity within lessons. Student involvement beyond memorization is an essential building block for learning science and math.

Spring starts on the first day of September, right? Not if Dr Tim Entwisle, director of the Royal Botanic Gardens in Melbourne and the author of 'Sprinter and Sprummer', has anything to do with it. Here he argues we should scrap the European approach and adopt a five season model.

"Poplocks are a very clever system for making movable papercraft fastenings with die-cutting and folding. The Paper Pose-Ables site has a bunch of downloadable papercraft toys you can print out and make, as well as pre-cut/scored kits you can buy, for making fabulous poseable robots and other cool figures. .. the Poplocks system really makes for a great, semi-rigid joint for the toys."
