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. Learning to Go is a collection of lesson plans, resources, handouts, and tips for teachers wishing to incorporate mobile devices, cell phones or BYOT (Bring Your Own Technology) into their teaching.
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. Explore the many activities below.
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.
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)
