Homologous Shoes
Students examine the concept of homology by observing their shoes and those of their classmates. They summarize the observations of everyone's shoes relating it to chromosomes in cells. They share their observations with the class.

What is the purpose of Karyotyping?
Young scholars explain how karyotyping is used to diagnose specific genetic disorders. They use karyotypes to make observations and analyze chromosomal errors. This activity can be completed online or without computer access.
