10-13-17 Types of Investigations Review Cambridge Science

Do Now: Complete in your Science Notebook Think about scientists whom you’ve read about, seen on TV, or maybe even know personally. Draw a picture (or describe in words) what a scientist looks like and what a scientist does.

HW Review: What type of Investigation? Observational, because she is simply making observations about the tissue of the celery and not comparing it to anything else. Comparative, because he is comparing the number of stomata on a hibiscus leaf versus an ivy leaf. Experimental, because he is changing the temperature of the potatoes and measuring the effects on enzyme activity. He also has a control group Experimental, because she is changing the pH levels and measuring if there is an effect on bean growth. She also has a control group. Comparative, because she is comparing how the worm moves under different conditions. (Yes, this is different from what I told you previously. I apologize for my mistake!) Observational, because he is simply making observations about the traits of each food sample, in this case, whether it had starch.

HW Review: Determine the Type of Investigation Based on a Scientific Research Question How frequently does it rain in the month of August? What are the similarities and differences among prokaryotes and eukaryotes Observational What is the difference in temperatures at locations A and B at 12:00 noon? What is the effect of sugar on yeast? Comparative What is the gestation period (amount of time for a fetus to develop) for a manatee? How does running affect heart rate? Experimental What is the difference in the pH of the water in a clean aquarium versus a dirty aquarium? How many insects are there in a given area? How does temperature affect the growth of mold?

Group Work: Meet the Scientist Lesson Objective: Students will be able to give examples of how scientists can gain scientific knowledge without experimentation Groups will be assigned a scientist to read about. After you read about the different scientists, answer questions about them in the “Meet a Scientist” worksheet. Then each group will share with the class a summary of their scientist's work and the methods they use in solving problems. You can do this by creating a drawing or acting it out.
