Modeling a Sneeze: Kinematics in Pictures
Social distancing recommendations specify we keep at least 2 meters away from each other. Why? To answer this question, we’ll simulate and model the trajectory of particles in a sneeze. Using pictures and graphs, instead of blindly plugging numbers into equations, we’ll solve what is essentially a projectile problem. We’ll also learn about distributions while determining the average force and energy exerted during a sneeze.

Waves…Dynamic? Delicious? or Dangerous?
Rising ocean levels, record high water levels in the Great Lakes – both have unleashed great destruction where waves impact shorelines. However, waves are more than just agents of destruction. They serve as the basis for energy transfer throughout the world around us. We’ll take a look at wave behavior through a series of hands-on and digital experiences to bring the subject to life. In the end, we’ll leave you with a tasty model you can construct to perform your own investigations on wave properties.

Ten Ways the Earth is Dangerous To Humans
We are currently in the midst of one of the worst pandemics of this generation, but it is important to remember that there are also many non-biological catastrophes that nature can throw at us and that a large reason that our global population has grown so large so fast (now approaching 8 billion) is that Earth has been relatively quiet for the past two centuries. In this presentation, Professor Wysession will take us through a Top-10 list of Earth and planetary events such as supervolcanoes, asteroid impacts, magnetic field reversals, massive underwater avalanches, and enormous solar flares that have significantly impacted life in the past and could do so again in the future.
