1. Wake-up (5 minutes)
Explain the difference between responding to a stimulus and adaptation.
A friend argues that a rock is a living thing. What are two characteristics of life that you would use to convince them otherwise.

2. Wake-up Explain what the term denature means?

4. Robert Hooke
Hooke is said to be one of the greatest experimental scientists of the 17th century.

5. Developed “1st” compound microscope

11. Hooke was responsible for giving the cell its name
. . I could exceedingly plainly perceive it to be all perforated and porous, much like a Honey-comb, but that the pores of it were not regular these pores, or cells, were indeed the first microscopical pores I ever saw, and perhaps, that were ever seen, for I had not met with any Writer or Person, that had made any mention of them before this. . .
Hooke was responsible for giving the cell its name

13. Made some of the most important discoveries in Biology
Anton van Leeuwenhoek
Inspired by Hooke
Made some of the most important discoveries in Biology

14. Made over 500 microscopes. Showed much more details than previous microscopes.

16. 1st to look at Bacteria in our mouth
" In the mouth of one of the old men, Leeuwenhoek found "an unbelievably great company of living animalcules, a-swimming more nimbly than any I had ever seen up to this time. The biggest sort. . . bent their body into curves in going forwards. . . Moreover, the other animalcules were in such enormous numbers, that all the water. . . seemed to be alive."

17. 1st to look at blood; found Red Blood Cells

18. 1st to examine their drinking water under the microscope; found TONS of small swimming organisms (protists)

19. Studied law; his hobby was Botany (study of plants)
Matthias Schleiden
Studied law; his hobby was Botany (study of plants)
Prior to Schleiden, everyone studied plants based off of physical characteristics; he use a microscope.

20. 1st to recognize cells in plants; he determined that plants are made up of cells

21. Theodor Schwann -Studied animals
-Discovered that animal tissue is made up of cells

24. Rudolf Virchow
Doctor
All cells come from pre-existing cells

26. Wacky History of the Cell Theory
Listen for the three components of the Cell Theory.

29. Proper Microscope Techniques
1. Make sure that stage is at the lowest position.

30. Proper Microscope Techniques
2. Make sure that lowest objective is set

31. Proper Microscope Techniques
3. Place slide securely on the stage

32. Proper Microscope Techniques
4. While viewing through eyepiece, move stage up

33. Proper Microscope Techniques
5. Once you see something, use fine focus

34. Proper Microscope Techniques
6. Never move stage again; just objectives and fine focus.
