Chemistry 1 – We first developed a “rule” for using a ruler (or any other measuring device). All three classes came up with a version of “ESTIMATE ONE PLACE FURTHUR THAN WHAT THE RULER TELLS YOU FOR SURE.”
We then started using a variety of metric measuring devices, divided into various increments (m, dm, cm, mm). We are working on measuring different objects around the room in these scientifically standard units (metric).
Physics 1 – We continued to work on graphing in LoggerPro. I demonstrated how to “linearize” a set of data that isn’t linear, and then write and equation of the line (EOL) for the linear fit line. Students started practicing graphing sets of data on their own and are working on writing the correct EOLs.
Chemistry 2 – Groups were finally able to share their lab data that determined the Volume one Mole of gas would take up at STP. Most groups had 3 trial averages near the accepted value of 22.4 L/mol. From here we calculated the Ideal Gas Constant and will be using that in the Ideal Gas Law model.
