Science Methods II - Week 14
1. What did you do in lab today? a. In lab today we began by discussing our interviews with elders in our small groups. The next thing we did was look at amounts of CO2 in the atmosphere from the 1950s to today. We then looked at jars with one different colored bead per 1 million beads. This helped us get a context for what parts-per-million looked like. We talked about, and watched a video on why CO2 changes seasonally, but how there is still a clear rise globally. We then looked at a simulation of how different greenhouse gasses affect infrared and visible light particles. We also watched a video explaining how greenhouse gasses absorb the infrared light emitted by the earth and as more gasses remain, more light is trapped in the atmosphere, warming the earth. We then talked about how the surface temperature is increasing globally, and how the hottest 10 years in history have been in the last decade. ...
