Kirk gets to start us out this week and he's all ears. Ears are weird but all those shapes actually mean something. Learn how the shape of an animal's ears can tell us about their habitat and behavior.

Rachel is up next and she goes on on the ice to tackle the question of why does ice on lakes crack in the winter? It turns out it relates to some of the very strange properties of frozen water.

Victoria introduces us to The Hot Chocolate Effect. Did you know that hot water sounds different than cold water when it is poured, stirred or moved through pipes? It all comes down to bubbles.

Rachel rounds out the episode with a creature feature on Kangaroo Rats/Kangaroo Mice.

On this week's show, Victoria kicks things off with a discussion of Chirality and how the study of the "handedness" of molecules could actually lead to the creation of completely new forms of life. It's a bizarre thought experiment with very real and dangerous consequences.

Rachel brings us a creature feature, the fish-scaled gecko. This strange creature has an amazing defense mechanism that is both fascinating and gross.

Kirk ends things with a salute to Groundhog Day and he dives into the possible science behind why we think these giant ground squirrels can predict the weather.
