Micropipetting: Measuring and moving small volumes
In this lesson, students will engage in activities to teach them the proper way to use a micropipette and familiarize themselves with commonly used metric units and measurements. Students will use X-Y coordinates and colored liquids to generate ‘pipette art’ and test their precision by pipetting specified volumes. Additional lab activities to reinforce these concepts include a card sort, writing activities and a “Roy, Gee, and Biv’s Challenge”. These can be found under ‘Supplemental Materials’.
In the online version of this lesson, students learn about micropipetting by engaging with a series of videos and simulations and practice reading the volume settings on different sized micropipettes.
- Accurately and precisely measure small volumes, in metric units of microliter, using a micropipette
- Familiarity with the following concepts may be helpful for students prior to using the lesson resources.
- Metric scale for volumetric units (liter, milliliter, and microliter)
- Usefulness of working with small volumes in a forensics or basic research setting
