1. Cell Structure
ACOS #4.) Describe similarities and differences of cell organelles, using diagrams and tables ACOS #5 .) Identify cells, tissues, organs, organ systems, organisms, populations, communities, and ecosystems as levels of organization in the biosphere.

2. Take 10!
Today, we will be constructing a K-W-L chart on our topic, the cell and the microscope
K- What we already know W- What we WANT to know L- What we have learned

3. Something to Think About!

4. 7.1 Life is Cellular The Discovery of the Cell
Opening Questions
Why are microscopes important?
To observe living things
Can you see the same things with your naked eye as you can under the microscope?
NO, what’s different?
What makes up every living thing?
CELLS
What are cells?
Basic units of life

5. Early Microscopes
Robert Hooke- he used an early compound microscope to look at a thin slice of cork, a plant material. Under a microscope cork seemed to be made of thousands of empty “chambers”. So, Hooke called them cells because it reminded him of monastery's tiny rooms.
We now know that cells are NOT empty, but they contain what?
Living matter!

6. Early Microscopes
Anton van Leeuwenhoek- around the same time as Hooke he used a single-lens microscope to observe pond water. The microscope revealed tiny living organisms

7. The Cell Theory Who is responsible for this?
Schleiden (plants), Schwann(animals), and Virchow
The Cell Theory states:
All living things are composed of cells.
Cells are the basic units of structure and function in living things
New cells are produced from existing cells
If you want to know more on certain scientist responsible for this theory, then look at page at the timeline! 

8. Exploring the Cell
Electron Microscopes are capable of revealing details as much as 1000 times smaller than those visible in light microscopes
Two types are TEM(transmission) and SEM(scanning)
One difference in the two are that with scanning a scientist can study parts of a living organism and with transmission only a nonliving sample can be studied

9. Prokaryotes Definition?
Prokaryotic cells have genetic material that is not contained in a nucleus.
Want an easy way to remember this?
What does the pre-fix PRO mean?
Pro means “before” so think of before the nulceus

10. Eukaryotes Definition?
Eukaryotic cells contain a nucleus in which their genetic material is separated from the rest of the cell.
What does the pre-fix Eu mean?
It means true or good, so with this one think of it as having a true nucleus!

11. Activity- time limit is 15 minutes
There is an old saying that says “seeing is believing”, but is this statement correct…?
Put yourself back in a time before microscopes were invented. You’re an average town member with a love for scientific research. Your goal is to convince me, the mayor of this town to loan you money to research the cell by inventing a microscope.
Some ideas to keep in mind-
What will your microscope look like?
How advanced will it be?
What powers will your microscope have( be realistic)
Who can use this?

12. Activity: Time limit is 15 min
 I want you to create a proposal to me, Mayor Clayton, convincing me of loaning you the money needed. You may do a formal request, an informal request, a song, a poem, or anything else that will convince me, but you must inform me of the following things,
Why should I choose you? (what makes you better than your opponent)
What are your advancements?
What sort of parts will you use?
What will I be able to see with the help of your microscope?
What will your light source be? Keep in mind the time!
Compound microscopes are what you should be inventing, so keep in mind that you need two lenses

13. Exit Slip time limit is 5 minutes
For today’s exit slip we will complete the “L” part of the KWL chart that we started during the bell ringer at the beginning of class.
What have YOU learned during today’s lesson that you did not know before today?

14. How Cool is This??
The Cellscope

15. How Cool is This??
The Cellscope

16. So, don’t forget- microscopes are not what they use to be and will continue to change!!
