This game allows students to review key Genetics unit vocabulary while promoting collaboration. Print, cut, and randomly shuffle the cards, then distribute among students. The student with the "Begin" card starts the game by reading the first question, and the student with the appropriate answer must respond. This continues until the "Stop" card is reached. I project Online Stopwatch and use it to time my students, so they can compete against their best time to finish. You can also allow classes to compete against one another's best time. I was amazed by how engaged my students became when competing for a best time!
