Jagged mountains the size of the Alps have been found in Antarctica’s ice, giving new clues about the vast ice sheet that will raise world sea levels if even a fraction of it melts.
Using radar and gravity sensors, the experts made the first detailed maps of the Gamburtsev subglacial mountains, originally detected by Russian scientists [...]

Growing and observing the growth of crystals is an upper-elementary or middle school student inquiry-based science project, in-which they use critical thinking skills to make observations and share findings. In this investigation, students make observations of symmetry in crystals and compare the effects of temperature on the growth of crystals.
Most minerals occur naturally as crystals, which [...]
