Academic standards correlations on Teachers' Domain use the Achievement Standards Network (ASN) database of state and national standards, provided to NSDL projects courtesy of JES & Co.
We assign reference terms to each statement within a standards document and to each media resource, and correlations are based upon matches of these terms for a given grade band. If a particular standards document of interest to you is not displayed yet, it most likely has not yet been processed by ASN or by Teachers' Domain. We will be adding social studies and arts correlations over the coming year, and also will be increasing the specificity of alignment.
In this activity, students learn why cell growth is limited and requires cell division. They explore the different phases of mitosis in a Web activity. They learn about uncontrolled cell division -- cancer, the oncogenes that cause it, and possible treatments. Finally, as an optional exercise, they consider different points of view concerning the cloning of humans.
1. Blow up a balloon and tie it off. Tell students that the balloon represents a cell. Then blow up a second balloon larger than the first and tie it off. Ask students:
Now explain how this changing ratio is related to cell division. Ask:
2. Show the Mitosis video with the sound off.
3. Show the Mitosis video again, this time with the sound on. Have students explore the How Cells Divide: Mitosis vs. Meiosis Web activity, and then ask them to draw and briefly describe each phase of mitosis.
4. Ask students:
5. Show the video How Cancer Cells Grow and Divide. Discuss the following:
6. Have students explore the Web activity How Cancer Grows to learn more about cancer growth and treatments for cancer. Discuss the following:
8. Then have students explore the different points of view in the On Human Cloning article. Discuss the following:
