Summary:
Explanations and demonstrations on how to use mathematical equations for various laboratory purposes, including those specific to SEA-PHAGES (such as phage titer calculations) and those that are used universally in most scientific settings.

Description

After completing the modules in the Laboratory Math resource, students should be able to:

  1. Demonstrate proper use of scientific notation and metric conversion in basic laboratory math problems.
  2. Identify and use equations to calculate the amounts of materials needed to make solutions and dilutions.
  3. Use dilutions and equations to calculate phage titers/plaque-forming units (pfu) per mL.

 

How is the resource structured to promote student development as a scientist? 

Self-efficacy- This module will build student’s confidence in completing universal basic laboratory math calculations that can be applied to SEA-PHAGES and other science courses.

Science identity- Once students can understand and complete the required laboratory math, they are more likely to self-identify as being able to do the work of a scientist.

Scientific community values- Understanding the laboratory math modules will allow students to apply and appreciate the translational nature of math across scientific disciplines.

 

Intended Teaching Setting

Course level:  any level of undergraduate student who has completed a basic mathematics course

Instructional Setting:  in-person classroom or online

Implementation Time Frame:  estimated up to one hour per module (4 modules total)
