Corn that is intended for consumption by humans or animals must be tested for the presence of the dangerous Aspergillus mold, which produces a toxin. In this virtual lab, look at a sample of corn under black light to see if it glows. Then, grind up the corn, prepare a solution, and use a test strip to determine whether aflatoxin is present. You’ll practice using a pipette, adding solvent to extract toxins, diluting a solution, and maintaining consistent procedures.
In this lesson plan which is adaptable for grades 6-12, students are placed on food safety patrol.They must the use UV light in the online interactive to detect mold on corn, then test to see if it contains a toxin that could make people sick. This lesson plan is aligned to Common Core State Standards. See more »
