Here is a list of all of the labs we did this semester… it might be smart to put all of them together. Crime Scene Lab Microscope Lab Cell Observation Lab Movement of Substances Lab Respiration Lab Mitosis Lab Enzyme Lab Having A Baby Lab Blood Typing Lab Analyzing Amino Acid Sequences The Chips Are Down! Skulls Lab
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. Use coarse adjustment to bring object into general focus. Use fine adjustment to see more detail. Switch lens to low power. Use ONLY fine adjustment to refocus. Switch lens to high power. Use ONLY fine adjustment to refocus. 1.Why should you NEVER touch the coarse knob after you have moved from scanning power? (2 reasons) 2.What is the magnification on high power?
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?
Station 3: During the Cell Observation Lab, we looked at different types of cells and their functions. Obtain Slide A and B from your teachers 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?
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 45 0 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 scanning power.
Station 5: During the Enzyme and Respiration Labs, we used graphs to represent our data visually. Observe the graph below. 8. Answer the question asked by the graph.
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.
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. 11.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? 12.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.
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 Lab? 14. What process did the activity with the colored dots and cloth model? 15. List one thing you learned from the Skull Lab.
