Time lapse pictures of a cell undergoing mitosis. During mitosis, the chromosomes shorten and thicken to move around. Each chromosome is made up of two chromatids that line up along the equator of the cell before pulling apart. The cytoplasm then divides to form two identical cells.
Ask students to produce a mural depicting the main stages of mitosis. The more able students could create the explanation which would accompany each stage of the mural.
