The number of new vocabulary words and science skills presented to students in our science classes can be overwhelming. Many students need and benefit from additional practice using the terms, definitions, and problems in a chapter or unit. This activity provides a fun way to review and reinforce using Punnett squares to solve genetic crosses. Best of all, students get immediate feedback when they type in an answer. The hidden picture will not be revealed when incorrect answers are entered.
