Simulate a cell by using dialysis tubing filled with starch solution. Lugol's solution placed in water outside the tubing will diffuse into the tubing, resulting in a colour change. Students infer the direction of particle movement. Have students make models of mitosis and meiosis from various materials, such as Plasticine, pipe cleaners, and string. Provide students with living examples from local environments to demonstrate types of asexual reproduction, such as fission, budding, and vegetative reproduction.
Students relate mitosis to processes of growth, repair, and replacement.
Students can use models and posters to illustrate the differences between sexual and asexual reproduction. Set up stations where students can examine various specimens, photographs, or models of plant and animal species. Ask them to identify and give reasons for reproductive processes used. As students study cells, they can demonstrate their knowledge by drawing diagrams and interpreting slides, pictures, or simulations. Skills, Processes, and Knowledge Have students construct models of a cell.
