This is an interactive digital glacier lab that will help students understand what glaciers are, what some of the formations and deposits look like, and will have students explore how glaciers grow and shrink, and how scientists go about discovering glacial movement speeds over time as well as finding out how scientists come up with the numbers of how long glaciers will last at current rates. Students will actually be the scientists discovering the rate of speed as they build their own interactive glacier using PhET. You will need computers that can run Java. You can't test that out by going to PhET and seeing if you can run their Java-based simulations. https://phet.colorado.edu/en/simulation/glaciers or if the Java version doesn't work, try https://phet.colorado.edu/sims/cheerpj/glaciers/latest/glaciers.html. This assignment is accompanied by my website at http://EarthScience.xyz/Glaciers, which has images, a slide show presentation, and a link to a YouTube video called Chasing Ice.
