Continuing with our study of pressure and volume, students learned about Boyle’s Law in Lesson 58. Class began with a Sci Guys video about Boyle’s Law:
After the video, students took down a few notes from the whiteboard (below) and then worked through the Lesson 58 Worksheet. For reference, students are also encouraged to review the Lesson 58 PowerPoint.
After wrapping up our work for now on the Chromosome Project, we transitioned to studying how cells divide. Mitosis, or somatic cell division, involves the division of one cell into two after all of the components of the original cell (including the DNA!) divide into two sets. We began by watching a Crash Course video about mitosis:
After the video, students were assigned to read pages 46-51 of chapter 4 (Cellular Reproduction: Multiplication By Division) of Inside the Cell. Students then answered the following questions in their lab notebooks:
- Explain the purpose of mitosis.
- Which cells undergo mitosis?
- Describe the phases of mitosis in detail (words and/or drawings).
- Explain what happens when cells divide uncontrollably. List the known causes of uncontrolled cell division.
This unit is focused specifically on NGSS Standard HS-LS1-4:
