RED SLIDE: These are notes that are very important and should be recorded in your science journal.

BLACK SLIDE: Pay attention, follow directions, complete projects as described and answer required questions neatly.

Keep an eye out for “The-Owl” and raise your hand as soon as you see him.He will be hiding somewhere in the slideshow

“Hoot, Hoot”

“Good Luck!”

Why do we age?

“Arrgh”

Young

Answer : It has a lot to do with our next area of focus.

“That question better get answered by the end of the unit.”Slide32

Research Opportunity! There are many theories about why and how we age. Who would like to tackle this question and report back to the class tomorrow? Slide33

Video (Optional)! Time Lapse of aging. One picture everyday for six years.A neat video for the end of class. (6 min)

New Area of Focus: Cellular Division

Mitosis: Cellular Division-

When one cell divides into two

Humans shed thousands and thousands of skin cells every hour. Some estimates put it around 600,000 skin cells an hour.

These cells need to be replaced…Mitosis.

We are not one celled creatures… Slide41

We are not one celled creatures… We are multicellular creatures made of trillions of cells. We needed mitosis to create and maintain our complexity.Slide42

Already millions of cellsSlide43

Video! Time lapse photography showing embryonic development of a fish. (Mitosis)

Important Note - Although mitosis will be discussed as different stages, the process is generally continuous.

Before we begin, we must learn about chromosomes.

Humans have 46 chromosomes in their cells.

Not sex cells which will be discussed later during meiosis.

“

Oh No!” “We’re doing it again.”Slide69

“I told you we’re doing it again.”Slide79

“

Oh No!”Slide87

“He’s dead!” “Just leave him.”Slide88

Chromosome: An organized structure of DNA and protein that is found in cells.

DNA wrapping and chromosome formation.Over 1.8 meters (6 feet) of DNA can be found in most cells.Slide93

Video! DNA wrapping and chromosome formation.Over 1.8 meters (6 feet) of DNA can be found in most cells.Slide95

Video Again! (Optional) DNA wrapping. Shows how 1.8 meters of DNA can be found in a single cell.
