1. *Buddy Reading: Cells--pg. 81/84 6L Directions: Please open your books to page 81 and read The sections an “Overview of Cells” and “First Observations of Cells.” Then do the same for page 84 “Development of the Cell Theory.” You will read in PAIRS  (A) with (D) and (B) with (C). (A) and (B) will be the first readers and (C) and (D) will be the first listeners. You will switch positions after each paragraph. Each time the reader finishes a paragraph, the LISTENER will ask the READER a question about what was just read. The reader will answer it. The listener will give the reader a if the reader got it right. If the reader got it wrong, the listener will give hints so that the reader can get it right. Both reader and listener will write the question and CORRECT answer down on page 6L. There should be 10 questions and answers total.

3. 6R6R 6L6L 08/22/11 OQC Standard 1a: All organisms are made out of cells that function in similar ways. Objective: Students will explain the cell theory. Title: Cell Theory *Do Now: 1. 2. 3. *Buddy Reading: Cells p. 81/ 84 1.1. 2. 3. 4. 5. 6. 7. 8. 9. 10. You Do: Cell Theory 1. 2a. 2b. 3. Helpful Vocabulary : Structure = what something is made out of and how its parts are put together Function= what something DOES; its JOB Microscope = a tool to see very small things Theory = a way of explaining something; it is supported by lots of evidence

4. *You Do: Cell Theory (page 84) Cells of Human Cheek 1.How did the microscope allow scientists to conclude that all living things are composed of cells? 6L Answer: It allowed them to look close up at different living things. They could SEE that all living things are made of the same tiny parts.

5. 2a.Why do scientists say that cells are the “building blocks” of life? Plant cells Brick Wall 2b. How do cells help organisms stay alive? Inside an Animal Cell Inside a Plant Cell Chloroplasts 2a Answer: All living things are made out of cells. They are the smallest living pieces that an organism is made out of. 2b Answer: get oxygen and food, grow, and get rid of wastes.

6. 3. Why would a cell divide in half? Answer: To make the organism grow bigger, to replace dead or injured cells, to grow a new body part for the organism. Onion cell White blood cell Bacteria Cell Sea Urchin Embryo

7. 7R7R 7L7L 08/22/11 OQC Standard 1a: All organisms are made out of cells that function in similar ways. Objective: Students compare and contrast the different organelles. Vocabulary: 1.Organism—page 4R 2.Cell—page 4R 3.Homeostasis--page 4R 4. Cell Theory—an explanation of the relationship between cells and organisms 5. Organelles = small parts inside a cell that work together to keep it alive Title: Organelles You Do: Organelle Chart p. 89-94

8. What is inside a cell??? PLANT CELL (compare to the diagram on page 90) ANIMAL CELL (compare to the diagram on page 91) What do you call the 12 small parts inside a cell? ORGANELLES!!!!!
