This is one of a series of laboratory activities built on the 5-E approach. Each activity provides opportunities for students to ENGAGE ←→ EXPLORE ←→ EXPLAIN ←→ ELABORATE ←→ EVALUATE.
Students learn the basic life cycle of the fruit fly, Drosophila melanogaster, and review three types of genetic crosses. They participate in a Fantasy Lab where each step in a hands-on Drosophila lab is described and explained. After practicing Punnett squares for each possible genetic cross, students receive data collected in an actual college genetics class.
The vocabulary in this LITE version of the dry lab is less intense than in the full version. The data analysis is limited to monohybrid and dihybrid crosses. Data is provided for eleven student lab groups for both a monohybrid and dihybrid cross. Three genetic cross problems make up the EVALUATE task. This version can be used in any level class of biology, life science, or integrated science.
