This paper lab uses an organizer to help students understand the differences between polar bonds, polar molecules, and nonpolar molecules. To achieve this, students draw various models of several carefully chosen compounds. My class is fortunate enough to have MolyMods, so that is included in the lab as well. If you don't have them, you can substitute with another model type, gumdrops and toothpicks, or you can omit that section.
My labs are straightforward. Some of them are paper labs, but the ones that involve significant laboratory setup or calculations to be made on the part of the teacher are written about in a Teacher Notes section at the end of those particular labs. I use relatively safe and inexpensive chemicals. Of course, safety precautions are always noted at the beginning of the lab.
