How Do Salamander's Hear With No Ears?

In science we are currently talking about freshwater rivers, lakes and ponds. We have been talking about the wildlife that grows and lives around these areas. This week we talked about how some animals (specifically salamanders) do not have external ears to hear with. Of course the girls had no idea how it was that they would be able to hear an approaching predator. So, our science experiment had us take a tin tray (which was our ground) and turn it upside down, pour some salt on top and then demonstrate what would happen when the tray were hit with a spoon (which acted as our predator). The girls immediately recognized the vibrations as the salt particles jumped and moved. Of course, the experiment wasn't complete without having a Littlest Pet Shop join us!
