Using Experiments to Investigate Medical Mysteries
Using Experiments to Investigate Medical Mysteries
When doctors, researchers, and scientists gather evidence to solve medical mysteries, they often find the need to run tests or design experiments to gain information. For example, they may want to investigate whether or not a medication works to treat a certain disease; they may want to explore whether the choices we make, such as what we eat or how much we exercise, impact the way our bodies function. Experiments help scientists investigate these relationships and make conclusions.
Experiments need to be completed in a clear, logical, well-planned way to make sure that other scientists can repeat the work and that any conclusions they draw from the data are valid. To do this, scientists use a step-by-step process of experimental design to help set up and run their tests.
Later in this unit, you’ll have the opportunity to design your own experiments, but in this activity, you can explore how to set up investigations to answer questions you have about things you observe or evidence you collect.

Setting Up the Gummy Bear Experiment
Setting Up the Gummy Bear Experiment
- Label each glass for a different kind of liquid (tap water, salt water, sugar water, milk, vinegar, etc.)
- Add a half cup of water to the tap water glass.
- Add a half cup of water and 1 tablespoon of salt to the saltwater glass. Stir the salt until it is dissolved.
- Add a half cup of water and 1 tablespoon of sugar to the sugar water glass. Stir until the sugar is dissolved.
- Add a half cup of water and 1 tablespoon of baking soda to the baking soda water glass. Stir until the baking soda is dissolved.

In addition to your plan for your experiment, it is a good idea to get feedback from your participants about their perspective on your experiment. Write up a short questionnaire (2-4 questions) that you plan to ask each participant of your experiment in order to get feedback from them and their perspective on:

Write up a short questionnaire (2-4 questions) that you plan to ask each participant of your experiment in order to get feedback from them and their perspective on:
- Your process
- Their feelings on the experiment
- How they felt before/during/after the experiment
- Any other questions that might help you understand your results a little better

Is your hypothesis supported? Why do you think you got the results you did? Do you think anything affected your results that you didn't intend to happen? If you could do it again, what would you do differently and why? What did you learn from the experiment?

Your first priority today will be to conduct your experiment. You may utilize your classmates if necessary. If you do not have time, you can conduct/finish your tests during the next class period.

For your submission, you and a partner will submit one complete lab report. This may be typed or written and in whichever form you choose, i.e. poster, lab report, presentation, etc.

The work should be shown as the categories of the Scientific Method listed above. Each person should document their work in a separate color so I can easily see who did what work. You must both agree on ALL the content but can contribute separately if you wish. Both partners must each write their own conclusion.

Sections that must be CLEARLY included in your design report:
- Research Question
- Hypothesis
- Variables, both independent and dependent
- Materials Needed
- Control
- Procedure
- Data Collection - a table/chart
- Data Analysis - Create a graph and identify any outstanding information or patterns. Tell us what this graph tells us about the data.
- Conclusion
A lot of the research questions and hypothesis I have seen are very similar. The research question should be broader, such as does yoga change a person's pulse?

The hypothesis should be a prediction about HOW you think a person's pulse will change. For example, I think yoga will increase a person's pulse.

Each partner must write their own parts of the lab report in their own color. However, each person must complete their own written conclusion section.
