All About You: Structure and Function of Cells

Teacher Education Course2016-2017

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

Humans are made up of animal cells

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?
