Cool Antarctica, pictures of Antarctica, facts and travel guide What Is a Volcano? : Twig Volcanoes are our most explosive landforms. Able to eject molten rock, and clouds of thick ash, high into the atmosphere... With devastating consequences. Volcanoes mostly occur along destructive and constructive plate boundaries, where plates are pushed together or dragged apart. Destructive or constructive boundaries Cracks or weaknesses allow magma to rise up from below the Earth's crust. Pressure builds up, which then releases suddenly, causing the magma to explode – a volcanic eruption. Magma that reaches the Earth's surface is called lava. Lava This molten lava eventually cools to form new rock. After more eruptions over time, the mound of rock builds up, forming a cone-shaped volcano. Volcanoes all have the same key structure... A collection of magma underneath the volcano forms a hot, bubbling furnace, called the magma chamber. Magma Chamber The main vent allows this magma to escape. Main Vent And secondary vents... are smaller outlets the magma can travel through. Secondary Vents Crater
Learning to Go: Lesson Ideas for Teaching with Mobile Devices, Cell Phones, and BYOT Every day, people around the world communicate, connect, and learn digitally on the go. Our students spend hours with their devices and digital tools. Imagine if some of that time was spent learning your content. Imagine your students learning by creating, playing, translating, editing, curating, researching, and brainstorming digitally on cell phones, mobile devices, laptops, tablets, iPads, Chromebooks, and consoles.
Understanding penguin response to climate and ecosystem change Welcome to the Penguin Science Education Page! Here you will find fun and educational activities to help students learn about Adelie Penguin life, history and their relationship to climate change. Students can send questions to the researchers who study penguins, check the nests of penguins as they raise the chicks, and (from Oct-Jan) even receive a postcard from Antarctica! Adelie Penguin's existence in the far southern region of our planet. The average day in the life of a penguin is filled with adventure and drama, as they struggle to live and thrive in a challenging environment and changing climate of Antarctica.

Antarctica Tours & Travel | Intrepid Travel AU Top responsible travel tips for Antarctica 1. Don’t use aircraft, vessels, small boats, or other means of transport in ways that disturb wildlife, either at sea or on land. 2. 3. 4. 5. 6. 7. 8. How the SAMR model improves teaching with iPad | learnmakerblog There’s a very easy way to make better use of the iPad in class. Simply become more aware of what you’re using the iPad for when teaching. This is where the SAMR model comes in, something I believe all teachers should be familiar with. The SAMR model is a 4 stage framework, illustrated below by the fantastic Sylvia Duckworth, creator of many great sketch notes. By using SAMR, you give yourself an easy to use self evaluation of your use of the iPad (or any other technology that you use to teach with). Substitution: Tech acts as a direct tool substitute, with no functional change Augmentation: Tech acts as a direct tool substitute, with functional improvement Modification: Tech allows for significant task redesign Redefinition: Tech allows for creation of new tasks, previously inconceivable The first two are termed enhancement, because the task is essentially the same as before. Let’s look at a straight forward example to illustrate the various stages.
Visit Antarctica - Discovering Antarctica Why are more people able to visit Antarctica? We have already seen why people want to visit Antarctica for example its unique beauty and wildlife is appealing to people. But why are more people able to visit Antarctica? Study the transcript, data and graphs showing some of the different reasons why it is much easier to visit Antarctica than in the past. 1. “I visited Antarctica last year. 2. According to the Office of National Statistics Family Resources Survey for 2008-9 over half the households in the United Kingdom have an income of over £500 per week and almost 20% have an income of over £1000 per week after taxes etc have been paid. 3. In 1951 66% of manual workers had two weeks holiday. How have holiday entitlements changed?
Guide: Using the SAMR Model to Guide Learning | That #EdTech Guy's Blog Technology is an immense tool that can transform the way students learn. One of my favourite quotes which demonstrates this comes from Steve Jobs: “What a computer is to me is it’s the most remarkable tool that we’ve ever come up with, and it’s the equivalent of a bicycle for our minds To me, this quote best illustrates the potential impact technology can have on learning. (Image Credit: Jonathan Brubaker (@mrjbrubaker)) Background The SAMR Model (above) was developed by Dr. – Enhancement (Substitution and Augmentation) – technology is used just to enhance a task– Transformation (Modification and Redefinition) – tasks are designed in a way which would not be possible without the use of technology How does it work? – Substitution – at this stage, technology is simply used as an alternative tool for completing the original task with no real change in the tasks function. Example: instead of writing by hand, learners use an app like Pages to type up a report. (Image Credit: Ruben Puentedura)
Antarctic animals adapting to the cold Antarctic animals are exposed to some of the coldest environments on earth. Animals survive in these harsh conditions by reducing the percentage of body heat that is lost to the environment. This can be by physical means (generally evolved over many generations) or patterns of behaviour. Physical adaptations Thick, windproof or waterproof coats Many Antarctic animals have either a windproof or waterproof coat. Thick fat (or blubber) layers Whales, seals and some penguins have thick fat layers. Blubber layers can also be used as an energy reserve, for example male elephant seals can live off their fat reserves during summer. Small ‘extremities’ The term extremities is used to mean any body part that is removed from the main body. Specialised adaptations by emperor penguins Emperor penguins are highly adapted to cold environments – and as the only animal that breeds during the Antarctic winter, they need to be. Behavioural adaptations
Shackleton's Voyage of Endurance | Timeline 1914-1916 When he left South Georgia Island on December 5, 1914 in his bid to be the first to cross the Antarctic continent, Ernest Shackleton had no idea that the next bit of land he touched (save for remote Elephant Island) would be that very same South Georgia - a year and a half later and after having not so much as set foot on the Antarctic continent. The story of what happened in between, outlined below, constitutes one of the most stupendous polar survival sagas of all time. For more specifics on the expedition and its 28 members, see the dispatches and Meet Shackleton's team, respectively. August 1Endurance departs London the same day Germany declares war on Russia August 4 Shackleton offers his ship and crew to British government for war effort August 8 After Shackleton receives one-word telegram from Admiralty ("Proceed"), Endurance departs Plymouth October 26 With final crew on board, Endurance leaves Buenos Aires, Argentina for South Georgia December 7 Enters the Antarctic pack ice
People in Antarctica Is it very different living in Antarctica? In some obvious ways it is different from Australia, such as living among snow and ice and having very long periods of darkness in winter and light in summer. And of course it is very cold and often windy, like the top of a mountain. In other ways Antarctic life is quite like ‘home’ – people at the stations have fully insulated living and working quarters with their own rooms and bath/toilet facilities. Human impacts in Antarctica Antarctica is often thought of as a pristine land untouched by human disturbance. Unfortunately this is no longer the case. For a little more than 100 years people have been travelling to Antarctica and in that short time most parts have been visited and we have left more than just footprints. Human impacts include: harvesting some Antarctic species to the verge of extinction for economic benefit, killing and disturbing other species, contaminating the soils, and discharging sewage to the sea and leaving rubbish, cairns and tracks in even the most remote parts. Changing attitudes More recently attitudes have changed as we begin to realise that there are few unvisited places left on Earth and that they are of enormous value to humanity. Scales of environmental impacts in Antarctica Environmental impacts in Antarctica occur at a range of spatial scales. Global impacts of the industrial world show in Antarctica Finally, the Antarctic region is a sensitive indicator of global change. Sealing
Antarctic Summer Glacial dreaming The Mertz Glacier, named for Swiss explorer Xavier Mertz who died during an Australian expedition with Douglas Mawson in 1913 and whose body most likely remains in the glacier today, is an inhospitable, remote part of Antarctica between Cape de la Motte and Cape Hurley. The glacier was renowned for an exposed ice tongue poking 40 kilometres out from the Antarctic continent but in early 2010 a 97-kilometre long iceberg smashed into Mertz, resulting in the calving of a massive chunk of the ice tongue. In January 2011, a team of nearly 40 Australian and international scientists braved the Southern Ocean to deploy underwater cameras, moorings and sensors to study the glacier and its surrounding waters, with the mission of uncovering new information about the Earth's changing climate.
