When teaching the proper use of lab equipment, you must also give adequate instruction in how to make precise and accurate scientific measurements. I find that many students will need a short re-fresher on the metric system. As for accuracy and precision in making measurements, it is the nature of the teenagers I teach to rush, rush, rush to get through with the experiments, giving little thought as to whether or not their data seems reasonable or logical. If and when time allows, I often require my students to run multiple trials during an experiment to verify their results. Unfortunately, due to the nature of a school setting, students have learned that science occurs in a 45 minute period of time, and that the first set of data is perfect and acceptable. We, as teachers, do what we can do with the schedule forced upon us by our schools, but you must try to give opportunities that require students to repeat and verify lab data.
Here are some of the materials that I have developed to help with the instruction and reinforcement of these basic science skills:
Free Lab: Use of Lab Equipment
Lab: Making Metric Measurements (Length, Mass, Volume, and Temperature
Measurement Madness
Significant Figure Lab
