Lactose Tolerance: Human Evolution Kit

WARD470004-136 WARD470199-690
Students research why one-third of Americans are lactose intolerant, but most other cultures have a much higher intolerance rate.

  • For grades 9–12
  • Complete instructions included
  • Teacher-designed lab
  • Students research where and why lactose intolerance is high
  • Purpose for students: to learn how to make inferences based on research
In this lab designed by teacher Therese Passerini, students test milk with a glucose strip and introduce the enzyme lactase. After retesting, students notice that lactose in milk breaks down into galactose and glucose.

Students then research a world map to observe trends in lactose tolerance and make inferences on the inheritance and possible adaptive advantage of lactose tolerance in some populations. This kit is for grades nine-12.

Ordering information: This kit includes lactase, glucose test strips, map of the world, transparencies of the world map (color-coded), transparencies of pedigrees, and complete instructions. Milk is not included.
