Performance Assessment:
Students will choose either mitosis or meiosis, and create a two-dimensional model of the process. The model can be constructed on a poster board or cardboard base. Students are not to draw the processes, but instead use other materials such as string, popsicle sticks, and pipe cleaners to create the models. The phases and cell structures need to be labeled. Along with the model, have students write a fictional children’s story for the different phases of the process with character names and a plot. The story should be typed if possible, double-spaced, creative, and include one paragraph per phase.
