Sitting on top of the outer core, we find the mantle. this layer is by far the thickest layer of earth, about 1,800 miles thick! it also makes up about 85% of earth's volume. like the core, the mantle contains mostly iron, but in the form of silicate rocks. you might be surprised to learn that this rock actually moves like a fluid, similar to how silly putty moves. if you poke silly putty hard, it acts like a solid, but if you slowly pull it apart, it acts like a liquid. we call this ability of rock to move without breaking plasticity.the mantle can also be divided into two portions, the upper mantle and the lower mantle. the lower mantle is completely solid because, like the solid inner core of earth, the pressure is just too great for it to melt and flow. the upper mantle is also known as the asthenosphere, which flows as convection currents. convection occurs in all fluids and is the rising of warm particles and sinking of cool particles. so, as the material in the upper mantle warms, it rises straight up, and as it rises, it cools and then sinks back down.

picture a world where computers are building made-to-order personalized robotic arms and synthetic organs, drones are circulating above mars! due to the rapid growth of technology, the future has never been more unpredictable, and it presents a huge challenge in education: we are teaching students how to work in a future that we have never been unsure of. it is widely predicted that in eight years’ time, there will be more jobs in the fields of science, mathematics, technology and engineering than in any other discipline. and, as the technology continues to develop, it will soon become clear that addressing social problems will involve more innovative thinking, and analytical and technical knowledge than ever before. undeniably, there are no subjects that encourage innovative and creative thinking, deep thought, problem solving and independence more than the stem subjects. while it is widely commented on that there is a need to reimagine the ways stem subjects are taught in schools by embracing a more interactive and innovative approach to appeal to more students, it should come as no surprise that some of the most reputable educational organizations in the world are already implementing changes to embrace stem. harvard, for example, announced in 2014 that they were increasing their computer science faculty by over 50% and has since introduced computer science as a core subject for all freshmen. the urgency of supporting stem subjects at a young age is becoming more relevant than ever, as adopting a keen interest in the curricula needs to happen early. however, beyond the age issue is one of gender.
