Core A, Week 4

We have been learning about how scientists set up and conduct experiments.  In activity 4, we learned about controls, placebos, and how to look at and analyze data. In the Goldfish Respiration lab we used a control to compare the effects of cold on a fish's breathing. We also graphed our results using different sample sizes (our class and  all classes) to gather evidence to support or disprove our hypothesis. And, on Monday, we looked at  how insect repellents are tested and identified our Control, IV, and DV. The Goldfish lab was good example of a controlled experiment because we only tested one variable; Temperature.  The Insect Repellent experiment was not a good example, because some of the test subjects drank Mountain Dew and others did not, which gave us bad data for 2 of the repellents.

Key words
  • Independent Variable (IV) The variable that is changed or manipulated in an experiment.  The cause.
  • Dependant Variable (DV) The variable that responds to the change or manipulation in an experiment. The effect.
  • Control- a standard used for comparison that is not changed in the experiment.  
  • Controlled Experiment- An experiment that tests only one variable at a time. . 
Respond to both A and B by Tuesday 9/28 

A)  Use the link below to watch the Myth Busters video clip. Answer the following questions after watching the clip..  
  1. What was the hypothesis (if and Then)
  2. What was the control?
  3. What was the IV
  4. What was the DV
  5. Do you think this was a controlled experiment? Provide evidence to support your answer.

B) I would like for you to redesign the insect repellent lab so that it will be a Controlled Experiment. Describe how you would change it, so that we only test one variable at a time.

Core B, week 3

Last week we learned how Dr. Goldberger used observations, inferences, hypothesis, and the scientific method to solve the problem of Pellegra.  This week we conducted our own investigation to test a new headache medicine.  
We simulated a clinical trial using two kinds of pink medicine; one was the "new medicine" and the other was a placebo or "fake medicine". Half the class received the placebo or control and the other half received the new medicine being tested.  The results of this clinical trial revealed 3 possible outcomes; the headache is not cured, the headaches is cured, or the headache is cured, but you suffer side effects. Use your lab report and histograms to help answer the questions below.

Key words
  • Clinical Trial- a test performed on volunteers, typically to test medicines, before the products are made available to the public.
  • Control- a standard used for comparison that is not changed throughout the experiment.
  • Placebo- a control that simulates a medicine, but doesn't have the active ingredient.
  • Sample Size- the amount of people or things being tested. Larger sample sizes give more accurate data.
  • Trade-Off- something given up for something gained.
Respond to both A and B by Tuesday 9/14

A) I would like for you to reflect or summarize what we've learned from activity 3, Testing Medicines. Please include all 5 of the above key words into your comments. Your response should touch on the key themes highlighted above and should be at least a paragraph in length.

B)  Use this link to investigate types of clinical trials being conducted at the University of Cincinnati.  http://www.uc.edu/ucresearch/clinicaltrials.html  Go to General information and click on "types of trials". Summarize what happens at each of the 3 phases in your comments
