• RED SLIDE:

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

Pili -Nice neat notes that are legible and use indentations when appropriate. -Example of indent.

-Skip a line between topics -Don’t skip pages -Make visuals clear and well drawn. Please label.

• 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.

• • Activity! Observing Sewer Lice

(Pediculus deficus)

• Larger Cousin of (Pediculus humanus)

• Sewer Lice – Discovered in 2003 by Dr. Katie Matthews in a sewer system of Cleveland, Ohio.

– Largest of the dark colored louse.

– Is a food source for many animals.

– Can be found in fecal samples in the sewer.

– Has a very fleshy mesocarp.

– Decreases in size when dries up.

• Do turtles spontaneously emerge from the sand as new life?

• Answer. No, turtles lay eggs in the sand that hatch into baby turtles.

• Spontaneous origin (abiogenesis): Life came from non-living materials.

• On Origins Optional PowerPoint in activities folder.

– This can also be run at the end of the unit.

• Life only comes from pre-existing life. Except of course for the first form of life. Science has disproven but also suggests abiogenesis.

• Cells Available Sheet for Classwork.

• Pasteur' s experiments (1860' s) showed that micro-organisms are even carried in the air.
