Structure and Function of CellsYou loose about 8 pounds of this every year of your adult life. What is it?
For reference, a gallon of water weighs about 8 pounds

Structure and Function of Cells
SKIN!

Structure and Function of Cells
What questions does this phenomenon
of shedding skingenerate?

Structure and Function of Cells
Humans shed their entire outer layer of
skin every 2-4 weeks.?

Structure and Function of CellsEstimates
of skin cell sheddingare between
1 and tens of millions of cells per day.
What new questions does this generate?

BioVisions Project“We embarked on a project … that would give students … a mental image of the cell as a large, bustling, hugely complicated city that’s occupied by micromachines. These micromachines really are at the heart of life.”
David Bolinsky, medical illustrator

Next Generation Science Standards Science and Engineering Practices
• Asking questions• Developing and using models• Planning and carrying out investigations• Analyzing and interpreting data• Constructing explanations• Obtaining and communicating information
Disciplinary Core Ideas• LS1 From molecules to organisms: Structures and processes• LS3 Heredity: Inheritance and variation of traits
Crosscutting concepts• Cause and effect• Scale, proportion, and quantity• Systems and systems models• Structure and function• Stability and change

Next Generation Science StandardsThe intent of the NGSS:
"Grade-appropriate elements of the science and engineering practice(s),
disciplinary core idea(s), and crosscutting concept(s),
work together to support students in three-dimensional learning to
make sense of phenomena and/or
to design solutions to problems.“

Today’s agenda Microscopy
• How can we use a compound light microscope to see our cells? Don’t Burst My Bubble
• What are the characteristics of a cell membrane? The Great Divide
• What are the cellular mechanisms that occur when cells divide?
Other Lesson on Cells Cells as Stores
• What are the functions of the major animal cell organelles? Teeny, Tiny Cells (and Cellular Transport)
• Why do cells have to be so small?• How does cellular transport affect cell function?
