When students are introduced to the unit on genetics they almost immediately ask about eye color. This interactive lesson demonstrates how more than one chromosome is involved and how the pigment melanin in the eye is determined by genetics. A fun and engaging way to provide an explanation about eye color with a bit of a twist. Students will pretend that alien eyes follow the same complexity as humans. The aliens are on a mission to study the genetics of the human eye to better understand their own kind. So with alien fun, students are really learning about the complexity and genetics of their own eyes.
