My youngest students were learning about rocks last week. One of the first thing they learned in this unit was igneous rocks. So...it was time to take off to the volcano in SL and bathe in magma. The volcano was almost realistic. It had burning magma, gas and it erupted every hour. (My students screamed when the eruption started) However, there we no notecards we could learn from at all. So while my students were busy jumping into the magma I was busy lecturing them in the local chat. :(
