GLOBE Observer Land Cover is a citizen science app that verifies and contributes to satellite imagery. GLOBE Observer Land Cover helps scientists improve the different kinds of maps they make with satellite imagery. On the most detailed satellite-based maps, each pixel is about 330 feet by 330 feet. This means small areas such as city…

Learning about Plate Tectonics
This week is all about plate tectonics, the foundation of both modern geology and the surface of our planet! The idea of plate tectonics was a long time coming but in the late twentieth century it became clear that every part of geology and our world’s ecology was tied, at least partly, to the…
Learning about Sound
BOOM! BONG! KNOCK! RING! Sounds are everywhere. Some sounds are loud, some are quiet, some are pleasant, and some are irritating or even dangerous. This week students will learn how to measure sound using a smart phone app, how different materials affect those measurements, how music produces pleasant sounds by creating perfect intervals, and how…
Learning about the Moon
You might look outside most nights and see the Moon—that round, astronomical body that orbits the Earth. But do you know what processes make the Moon look the way it does or what it would be like to be on the Moon? For this week’s STEM @ Home, we explore the Moon! Online Videos: Use…
Learning about Modeling
Scientists use models to understand how systems, processes, and events might play out in the real world. Scientists might develop models to simplify real-life situations and gain greater control over selected variables. Other times, scientists may develop models to add complexity and simulate how systems change if variables change. Either way, models are handy tools…
