Reviewing Cells

Biology

Students reviewed by drawing and labeling animal and plant cells and making a graphic organizer in class today from a CANVAS page.  Essentially review notes from text.    The quiz didn't work for 4B so it needs to be edited.  I somehow mistakenly imported the wrong quiz from the commons in haste. I'm so thankful for understanding students and retakes will be next class.  Many videos and review information are available at the Cell Structure and Function FB 4 CANVAS page.

What are the most powerful ways to review>  Should you review in class?  I do. Who doesn't like a study guide before an exam?  I cover key vocabulary terms and a few practice questions and allow class time to do this.  We do this in an Interactive Booklet of  papers folded in half to make  a 24 page booklet.  Each day we do two pages of review.  Diagram or drawing on the even left hand side pages and notes and definitions on the right.  Students are even using their earlier Interactive Notebooks to find the information.


 But I also believe in depth before breadth and science practices teaching the processes and science as the way to teach - so teaching to the test by reviewing goes against my teaching pedagogy.  However, I have rooms of 42 students and limited lab space.  I teach virtual bio.  I like that to be fine, but the real experiments should be conducted by kids at least four, 1 per term.

What are the best ways to review the structure and function of cells?  Diagrams, coloring plates, graphic organizer, cornell notes, organelle disorder essays, dioramas, ... My favorite way was candy in vegetable oil (in college my favorite way but utterly impossible in the classroom).  Licorice ropes for ER, Nucleus Oreo, Ribosome Nerds, Green Jelly Beans Chloroplast, Red Jelly Beans Mitochondria, Baggie Cell Membrane, Oil Cytoplasm, pretty much anything else for any other organelle.

Ideas for next class:  Demo the candy thing- would work great around Halloween and Review at Easter.  Who can donate a piece of candy?  Put in baggie.  Fill up with vegetable oil.  (Always an oreo for the nucleus).  Label and describe the purpose of each candy as you add it to the baggie to represent the organelle.  Create a graphic organizer of structure as you add the candy organelles.  When finished add the oil for the cytoplasm.  gasp.  Now raffle off a prize of candy in a random way for a class prize.  Students then add to the graphic organizer with the functions by doing a jigsaw technology project.  Groups work together to research and create a slide to inform the function of the organelle.  The slide is added to a class slideshow.  Students use this to complete their own graphic organizers and submit.  THEN groups make a movie tutorial or interactive quiz about their organelle's function.  Students are then tasked to write an essay about a human disease caused by a cell organelle malfunction,  give each student an oreo and explain that their individual essay should include three parts like an oreo.  An introduction, a body, and a conclusion.  Use pre-writing strategies, rubrics, peer review, and rough draft submissions to support and differentiate instruction.




AP Biology

I'm excited to embark on our lab inquiry projects for "after" the AP test.  I could review the experiments around the room for the regular biology classes to keep observations on.  Each class can be in charge of 1 of the 5 main experiments.

Groups choose topic and change variable per member of group. 

5 total experiments with 3 trials.  

Me, 1A, 2A

Onion  Root  Mitosis
Mold  Meiosis
Bacteria Classification
Wisconsin Fast Plants Genetics
Brine Shrimp  Hatching and Life Cycle
Planaria


We will do these labs together as a whole class

Transpiration
Transformation

Develop your own experiment by April 14
Two Weeks of Data Collection
Graph Results
Analyze Results

Create a Mini Poster to document your learning
Assignment is due May 15

Group Points 100

Individual Points 100
