Episode 23 – “If there’s one glacial feature, everything is named after it”

This week Shannon summarizes her field trip and John talks about rock slides and his coming travel. We also talk about organized patterns of dripping syrup.

Fun Paper Friday

This week we learn about stick patterns formed by viscous fluids falling on a surface. It could be honey on toast or telecommunications cable on the ocean floor. Check out the video as well!

Episode 22 – “It was like two Volkswagens Battling” National Parks

Join us this week as we talk about our favorite national parks while Shannon is on the road. Then we’ll talk about kinetic energy of empty and full beer bottles as part of Fun Paper Friday!

Fun Paper Friday

Have you ever thought about how much force a beer bottle can exert when you strike something with it? Bollinger et al. have! Do you think full or empty bottles are more dangerous?

What causes chocolate to get that white growth? This week we find out that it’s very similar to geological growths and investigated with similar techniques!
