Grade 6-College. Diffusion, which results from the random movement of molecules and other small particles, is essential to the life of a cell. In this kit's activities, students use agar cell models to observe the results of diffusion over a period of 10 min. Students then reinforce the results by using calculations to explore the relationship between diffusion rates and cell size and the importance of the ratio of a cell's surface area to its volume. For a class of 32.

Grade 6-College. For a class of 32. Diffusion, which results from the random movement of molecules and other small particles, is essential to the life of a cell. Many nutrients enter a cell by diffusion, and the same process discharges waste products. Diffusion occurs rapidly over short distances but more slowly over longer distances.

In this kit's activities, students use agar cell models to observe the results of diffusion over a period of 10 min. Students then reinforce the results by using calculations to explore the relationship between diffusion rates and cell size and the importance of the ratio of a cell's surface area to its volume.
 
 
 
 
Rated 5 out of 5 by from Powerful visualization for students The kit has high quality materials and is easy to implement right out of the box. My students love this lab and I enjoy it because students learn cell size and diffusion concepts so quickly with this lab. The mix of both qualitative and quantitative data is useful for student learning.

Rated 5 out of 5 by from Excellent I have used this kit for years. While the students may need help with the mathematical concepts involved, they readily understand the limiting relationship diffusion has on cell size
