Cell-ute the cell! Examine how surface-to-volume ratio relates to cell size through hands-on exploration, observe cell division under the microscope, and collect data on the stages of cell division in an onion root tip. Learners pull it all together in a laboratory report with a histogram generated in Excel.
- Before using the microscope, show a diagram of a root tip with the different zones
- Demonstrate what cells in interphase look like so learners can easily identify which cells are dividing and which cells are not
- Spark interest by reinforcing the concept that cancer (tumor formation) is simply uncontrolled cell growth
- Contains components for the classroom, laboratory, and computers, but it could be modified for use without computers
- Allows for self assessment through pre/post anticipation guide
- Provides two hands-on activities to connect knowledge
- Includes a rubric for lab reports with histograms
- Learners will need to recognize the stages of cell division and parts of an onion root tip, but the lesson does not provide this preparation
