Students will be able to observe and analyze the process of diffusion through the cell membrane. First, students need to prepare a microscope wet mount slide of red onion cell in distilled water. Then they need to take another piece of red onion skin and made a second slide using saltwater.
Students need to use a good quality microscope to make observations. Observing the diffusion process in real cells is difficult because they are too small to be seen easily. To understand how osmosis(water diffusion)occurs students need to perform a variety of experiments.
Students will enjoy this activity because they will learn about microscopy, cells, and diffusion but also will be able to apply the content to real life situations.
