About the Indigenous Weather Knowledge website Ten Fun and Challenging Geography Games for Students of All Ages Over the years I've tried dozens of online geography games for students of all ages. Many have come and gone over the years but the following geography games are still going strong. WikiWhere is a neat map-based trivia game. The goal of the game is to identify cities based on their descriptions.

We found the first Australian evidence of a major shift in Earth's magnetic poles. It may help us predict the next About 41,000 years ago, something remarkable happened: Earth’s magnetic field flipped and, for a temporary period, magnetic north was south and magnetic south was north. Palaeomagnetists refer to this as a geomagnetic excursion. This event, which is different to a complete magnetic pole reversal, occurs irregularly through time and reflects the dynamics of Earth’s molten outer core. The strength of Earth’s magnetic field would have almost vanished during the event, called the Laschamp excursion, which lasted a few thousand years. Earth’s magnetic field acts as a shield against high-energy particles from the Sun and outside the solar system. Without it the planet would be bombarded by these charged particles.

About the Indigenous Weather Knowledge website Cities turn to desalination for water security, but at what cost? This is the first of two articles looking at the increasing reliance of Australian cities on desalination to supply drinking water, with less emphasis on alternatives such as recycling and demand management. So what is the best way forward to achieve urban water security? Removing salts and other impurities from water is really difficult. For thousands of years people, including Aristotle, tried to make fresh water from sea water. In the 21st century, advances in desalination technology mean water authorities in Australia and worldwide can supply bountiful fresh water at the flick of a switch. Achieving water security using desalination is now a priority for the majority of Australia’s capital cities, all but one of which are on the coast.

8 Options for Making Digital Maps In yesterday's post about English Heritage's Map of Myth, Legend, and Folklore I included a mention of using StoryMap JS to create interactive maps. That prompted a response from Cindy Rudy who suggested the idea of using Thinglink or Google Earth to make similar maps of myths, legends, and folklore. That was my inspiration for this run-down of eight options for making digital maps.

When water is scarce, we can't afford to neglect the alternatives to desalination This is the second of two articles looking at the increasing reliance of Australian cities on desalination plants to supply drinking water, with less emphasis on the alternatives of water recycling and demand management. So what is the best way forward to achieve urban water security? An important lesson from the Millennium Drought in Australia was the power of individuals to curb their own water use. This was achieved through public education campaigns and water restrictions.

Ten Great Tech Tools for Social Studies Lessons Over the last decade I've written about a lot of excellent resources for social studies lessons. Over time some of those tools have faded away and others have moved to the forefront of my top recommendations. Here's my current list of ten top tools for social studies lessons. Timeline JS Timeline projects as as old as history classes themselves.
