Grade: 7 (6-8)


Summary

In this unit, students look at the components of cells and their functions and discover the controversy behind stem cell research. The first lesson focuses on the difference between prokaryotic and eukaryotic cells. In the second lesson, students learn about the basics of cellular respiration. They also learn about the application of cellular respiration to engineering and bioremediation. The third lesson continues the students' education on cells in the human body and how (and why) engineers are involved in the research of stem cell behavior.


Engineering Connection

Engineers design systems to remove harmful bacteria found in drinking water — clearly, they must know a lot about cell behavior in order to design beneficial systems. And, engineers use their knowledge of cells to make products that offer strong protection against harmful bacteria and also enhance the growth of beneficial bacteria (such as soap vs. compounds to break down harmful pollution). Through the process of bioremediation, engineers use their knowledge of cells to promote the growth of cells that break down toxic compounds into harmless byproducts which aids in the protection of our environment. From engineering tools for observation on the molecular level to chemical and bioengineering of natural fluorescent dyes to examine cell replication in an organism, engineering developments and design have helped advance research of all types of cells. Engineering influences science and medical research by facilitating the understanding of how cells are influenced in all directions by their environment and how they behave in our bodies.
