This fun lab can be used in any science class to introduce the concept of experimental design. It will allow your students to work with something near and dear to themselves, their fingerprints! In a simple and fun experiment, they will learn a little bit about fingerprinting but a lot about hypothesis, variables, data collection, graphing and data analysis.
Not only that, but this lab has a part 2 in which the students get to design their own experiment! This really emphasizes the Scientific and Engineering practices from NGSS, bringing STEM into your classroom. Your students will really enjoy this lab and it is a nice change from the classic scientific methods labs we have all done.
