Science at Bangor & in the News
We are wrapping up our unit on moving particles in chemistry. We used a PhET simulation to show us how changing temperature, volume, and number of particles affects pressure. We used the Gas Properties simulation to capture quantitative data that we could graph using Excel. A benefit to doing this lab as a simulation was that we could actually see how the gas particles behaved under the changing conditions. We used our data to figure out three different gas laws and used our particle model and kinetic molecular theory to explain why the gas laws work the way they do. We'll be wrapping the unit up by calculating what happens to temperature, volume, pressure, or number of particles when you change one (or more) of the other variables.
Science 9 spent this week working on our graphing skills. The beginning of the week was dedicated to making scatter plots, drawing lines of best fit, and calculating the slope. While there were definitely some overwhelming moments, the scientists in class pulled together & worked through the challenges. Thursday & Friday were spent learning about, & then making, bar graphs & pie charts. Pie charts presented another challenge, but I think once the first few sections were calculated and drawn that the process started to make a bit more sense. Next week they will put their skills to the test by taking answers to a survey question & making graphs to display the data.
