This lesson is an introduction to measurement and tools in science. It is easily adapted to include SI units, other equipment and estimated digits. The objectives and rubric are for the lesson as it is written but can be changed, depending on how you plan to use it. I have found that students don't understand how to measure or why science has specific tools and units. This lesson requires them to do some research, draw and explain the tools. and answer questions. I usually give them from 3-5 days to complete it at home and turn it in but with BYOD, you could give them time in class. I don't recommend using an entire class period but you could give them 15 minutes to start it so you can answer questions.
