Learners will build a 2D model of the Magnetospheric Multiscale (MMS) Spacecraft model. 

Learn about volcanic ash and watch a visualization of the Calbuco volcano to see how ash travels around the world. 

Examine (daytime) surface temperature and solar radiation received at locations found near similar latitudes using NASA Data.
