An extreme precipitation event in 2008 cost one town more than a million dollars in infrastructure repairs. Now, other municipalities can simulate how their homes, businesses, and facilities might fare if they experienced a similar event.

This resource was created as a virtual lab demonstration to help students understand the composition of rocks in the earth's crust. It practices using a dichotomous key. The presentation is set up as a storyboard to help students understand how rocks in the earth's crust consist of only a few types of minerals. Scientists use the physical and chemical properties of rocks to identify the mineral composition in the rock, thus identifying the rock type.  I use this interactive presentation to introduce rocks and minerals. Typically it is the precursor to a lesson on the rock cycle. It is highly interactive and gives the students immediate feedback. This is very useful in the e-learning classroom environment.
