Being able to correctly set up Punnett squares and determine what outcomes are made as a result from crossing traits is a foundational skill in biology and the study of genetics. Use these simple crosses, dihybrid crosses and even a few trihybrid crosses! This activity offers plenty of practice for all skill levels.

Put your students Natural Selection skills to the test with this two day activity designed to show how Evolution by Natural Selection works in the real world. Students design organisms and then hide them in the classroom. Those that are not found survive! The second day builds on the experiences of the first to see if the rate of success changes over time for the organisms. Includes procedure, data table, and open response analysis questions for assessment.

A set of simple problems for students to practice conversions between different units of measurement. Featuring simple units and also open response type questions with conversions involved.

Tell the Tale of Evolution by Natural Selection. Students can create a story that shows how life changes over time with words and illustrations. Activity includes all the steps that need to occur for change to effect an organism, Selective Pressure, Variation, and Selective Advantage. Work through and see who survives and don't forget to give it a name!
