A "hands-on" kit designed to enable students to virtually reach in and manipulate genes, chromosomes, and fruit fly parts under your direction. Over 25 lessons can be demonstrated, including Drosophila life cycle, mitosis and meiosis, mutants, phenotypes, and sex determination. Each kit contains a 30 × 40" jumbo-sized demonstration board, over 400 Plastick pieces that stick without glue or magnets, a 64-page teacher's guide with detailed lesson plans, reproducible student worksheets plus answers, and 2 storage boxes.
