DMNS+Field+Trip+23

My favorite part of the field trip was going to the Planitorium it was almost like 3D. Something that I learned was that there is a force field around our earth that deflecs astroids and stuff like that exept for once it was the one that killed all of the dino`s. another thing that I learned that when a astroid hits earths atmasphere it burns in to fire going up to 40,000 miles pur hour.
