COVID-19 News

My younger daughter sent me the following link to a Washington Post article entitled "Why outbreaks like coronavirus spread exponentially, and how to 'flatten the curve'" which I feel is worth passing along to Science-1A students. I'm hoping that it can be viewed without any cost.

Virus Simulation

I'm sure you appreciate the connection between rabbit reproduction, our hydrogen-oxygen explosion, Walt Disney's ping-pong ball and mousetrap demonstration, nuclear bombs, and the current Coronavirus pandemic. When you understand one, it is much easier to understand the others. This is for your enlightenment. You will not be tested on it.

The following links have useful general information:
