The 8th Grade Science students expanded their understanding of meiosis by creating a model of the main stages of the process. Students had to use motion tweens to create the movement of the chromosomes and chromatids and shape tweens to simulate the deformation of the cell. They also created symbols to represent the chromosomes and chromatids, which they reused in different scenes of the animation. Students who finished early had the option of adding navigation buttons for extra credit. Four visits to the lab were necessary to complete the lesson.
