One of my favorite presentations was the "Mega Minerals" one. In the presentation, they went over the properties of several minerals, such as nano-sized gold, tellurium, cadmium, aluminum, corundum, and graphene. They talked about the properties of all the minerals, what they are made out of, as well as how they can be used practically in industry. The last thing taught in the presentation was what industry needs in minerals for them to be usable, which were nano-size, high purity, customized surface properties, low weight, recyclability, and innocuous to human health.
Another good presentation was the "Desert Dinosaurs" one. This presentation talked about how many dinosaur fossils were found in deserts. The presentation also goes over different paleontologists that had discovered these dinosaurs, including Edward Drinker Cope and Othniel Charles Marsh. The last thing they talked about was the two types of dinosaurs that can be found, Ornithischia and Saurischia dinosaurs.
My last favorite presentation was the one about Fossils and Marine Fossils. In the presentation, the presenters discussed what fossils are, different types of marine fossils, and how they are identified. They also talked about where groundbreaking fossils were found and now stored, and how fossils are connected to modern animals and how that makes them important.
