Some Flipping Success!!

Students continue to impress me!

Because of the modified flipped structure of my lessons, I was able to spend a considerable amount of time coaching students in their understanding of the inner workings of the cell.

Students watched vodcasts on organelle structure and function, explored cell membranes, and investigated transport of materials across membranes.

The performance task given to students at the beginning of the unit was:

Science 10IB Cell Transport Assignment

Create a story that outlines the “life” of a newly created protein and its journey out of the cell.  You can use artistic license when showing the relationship the protein has with the cell components, however the story must clearly articulate the following scientific processes.

·         Graphic Novel 
·         Ransom Letter / Police Correspondence
·         Explanation without using the letter “e’
·         Song / Poem / Rap
·         Scientific Explanation with supporting electron micrographs.
·         Format of your choice

  1. DNA produces RNA which communicates with ribosomes. (2)
  2. Ribosomes on the rough ER create the protein. (1)
  3. Protein travels through the smooth ER, where lipids (fats) on the protein are synthesized.  (2)
  4. Protein moves to the Golgi Apparatus. (1)
  5. Golgi Apparatus modifies protein by adding some carbohydrates. (1)
  6. Protein leaves the Golgi in vesicles. (1)
  7. During the journey, oxygen diffuses through the semi-permeable plasma membrane into the cytoplasm. (2)
  8. Glucose enters the cell through facilitated diffusion. (1)
  9. Glucose and O2 combine in the mitochondrion to produce CO2 and water.        CO2 gas diffuses out of the membrane and water leaves by osmosis.(3)
  10. The protein encounters some evil ‘ions’ that have entered through active transport. (1)
  11. The evil ions force the protein to become evil. (1)
  12. Lysosomes bind with the vesicle containing the protein and digest it. (2)
  13. The lysosome binds with the plasma membrane and removes the now evil protein through the process of exocytosis. (2)

Marks:             /20

Take a look at some of the results.  You will be just as amazed as I am!
