We finished the documentary on asteroids, and discussed the implications of space rocks slamming into Earth. Even if humans are not directly struck by an asteroid impact, one complication would be the enormous dust cloud that would engulf the Earth for possibly years after. This would seriously alter the climate, and have drastic consequences for farming, for example. The closest we've experienced was the Krakatoa eruption in 1883, when the year after the event, the global temperature fell by over 1 degree Celsius. It took almost a decade for the planet to recover. We then started summarizing this course, and went back to first principles, i.e. the scientific method. To conduct scientific experiments, the scientific method must be fully understood, otherwise the results and conclusions are meaningless. In addition, other methodologies, such as following up on references, are needed to ensure a solid, scientific foundation. Jared is very strong on the scientific method, and he remembers it from a 5th grade science fair experiment. It is very pleasing to see how he has retained that knowledge, and I have no doubt that in a real-world situation he would know how to apply it.
