Presentation transcript:

What is the magnification on high power? Station 1: During the Microscope Lab, we reviewed the steps of focusing a microscope. Get a microscope from the table and review the following steps: Turn it on. Make sure stage is all the way down and scanning lens is in place. (SCANNING IS THE SMALLEST!!!) Use coarse adjustment to bring object into general focus. Use fine adjustment to see more detail. Switch lens to low power. (THE MEDIUM ONE!!!) Use ONLY fine adjustment to refocus. Switch lens to high power. (THE BIG ONE!!!) Why should you NEVER touch the coarse knob after you have moved from scanning power? (2 reasons) What is the magnification on high power?

3. Which colors travelled farthest up the paper? Station 2: During the Crime Scene Lab, we dissolved different pen samples in water to create chromatograms. There is a sample chromatogram below. 3. Which colors travelled farthest up the paper? 4. How did you use these chromatograms in lab?

5. Which slide is a plant cell? Which slide is an animal cell? Station 3: During the Cell Observation Lab, we looked at different types of cells and their functions. Obtain Slide A and B from your teacher’s desk. These slides show plant and animal cells. Focus each microscope and observe. 5. Which slide is a plant cell? Which slide is an animal cell? 6. How do you know? Write 3 structures plant cells have that animal cells do not.

7. Draw a picture of what the hair looks like Station 4: During the Movement of Substances Lab, we reviewed the steps of making a wet-mount slide. Obtain a clean microscope slide & cover slip. Place the specimen in the center of the slide. Add one drop of water to the specimen if it is not already in water. Holding the cover slip at a 450 angle, slowly lower the cover slip onto the specimen. If properly done, there should be no air bubbles trapped under the cover slip. Using a hair from your head, make a wet mount slide. (all supplies are at lab table one) 7. Draw a picture of what the hair looks like under LOW power.

8. Answer the question asked by the graph. Station 5: During several labs this semester, we used graphs to represent our data visually. Observe the graph below. 8. Answer the question asked by the graph.

Observe the images below. Station 6: During the Mitosis Lab, we used a computer activity to observe the phases of mitosis. Observe the images below. 9. Label each phase of mitosis. 10. In which phase do cells spend most of their time? A. B. C. D. E.

Station 7: During the Having A Baby Lab & Blood Typing Lab, we learned that genes make up chromosomes and determine who we are as individuals. A person is Gg for eye color. a. Is this their genotype or phenotype? b. Are they heterozygous or homozygous? c. If G = green and g = blue, what color eyes does the person have? A mother has Type O blood and a father has Type AB blood. Show, using a punnett square, the possible blood types of their children.

15. List one thing you learned from the Skull Lab. Station 8: During the Amino Acid Lab, Natural Selection Lab, and Skull Lab, we looked at different evidence in support of evolution. 13. What evidence did we gain from the Amino Acid Sequence Lab? (we did this during class) 14. What process did the activity with the colored dots and cloth model? 15. List one thing you learned from the Skull Lab.
