Time for another Forum Friday! As always, please leave comments about what you liked and what you would like to see more about. What did you think about our stories? Do you have a book or show you want reviewed? Have any resources you would like to see discussed? Have you made an interactive or other resource that you think might be beneficial to others? Let us know.

In the meantime, we have discussed different maps showing the world through geologic time (including some great apps) and ways of showing the tree of life.

On Facebook we celebrated National Fossil Day and Earth Science Week, looking at fossilized arthropod brains, new skulls of Homo erectus and what that means to our understanding of human evolution, how cartilage helped dinosaurs get so big, and learned about the origin of flowering plants. We learned a website letting you make your own geologic time chart. We found a great video discussing what phylogenetic trees are and how to interpret them.

Going along with Earth Science Week, we found special Earth Science Week resources and a STEM Student Research Handbook put out by the NSTA, as well as resources available at Scitable. We discussed the pros and cons of the NGSS and the benefits of preschool education.

We learned about unusual deep sea creatures off the East Coast, more ways to tell moths and butterflies apart, how Black Skimmer birds can skim, and how the arapaima’s armor protects them from piranha. We saw how color evolved and its role in mimicry, how hands came before bipedalism, and how epigenetics affects evolution (it’s not just about mutations).

It’s your turn. What do you want to talk about?
