Here’s what is on the table when AP Chemistry students in Susan Fourness-Ewell’s class are working in the library–laptops, notebooks, textbooks, paper, pens, pencils, and of course, a Titleist hat. They were researching how the properties of atoms change with the atomic number. Need to know more? An example–the radius of an atom changes as the atomic number increases. After the research, students plotted the changes using a spreadsheet and graph to look for patterns.
