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.

Learning Objectives

  • Accurately and precisely measure small volumes, in metric units of microliter, using a micropipette

Prior Knowledge

  • 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

All Babec labs are well organised and modelled effectively with clear, helpful procedural instructions, easily transposed to the classroom.

The online resources are SO well done! The best I have ever had. Very little modification to make them clear and easy to follow. I have done two BABEC lessons and they are so well made that they made teaching online fun again.

When doing the BABEC labs I consistently hear students say they feel like "real scientists."

Well organized and scaffolded; flexible structure and can be used partially or as a whole. This unit can be used as is...superbly written and thought out...incorporates many skills and allows student collaboration and student choice/voice.

Thank you for creating these curriculum materials. I am beyond grateful for the quality lessons, on-the-point figures/videos, and easy-to-navigate biotechnology curriculum.

The level of support really made the whole process easier and encouraged me to continue incorporating biotech into my curriculum. Thank you for the live assistance during the labs and for responding to inquiries so promptly and with such urgency.

Really well thought out curricula. Great to see "old" activities that have been re-imagined with lots of consideration to NGSS.
