Testing Common Myths Using the Scientific Method

Explore how we can scientifically test common myths in everyday life, such as whether eating chocolate causes zits, shaving makes hair grow back thicker, or if reading in dim light truly damages eyesight. Utilizing the scientific method, we will outline the steps involved: identifying a problem, forming a hypothesis, conducting experiments with control and experimental groups, and analyzing data to reach conclusions. This approach not only debunks myths but also reinforces the importance of evidence in understanding the world around us.

  1. How can we test these? • Eating chocolate causes zits. • Shaving make hair grow back more. • Drinking coffee will stunt your growth. • The full moon makes people restless. • Reading in dim light damages a person’s eyes.

  2. Scientific Method • Process used by scientists (everyone/anyone) to determine a solution. • “Method” means there is a consistent way of doing something • To determine a solution you must have a problem.

  3. Steps of the Scientific Method • Hypothesis • Data 1. State the problem 2. Gather information about the problem 3. Form a hypothesis Suggested solution to the problem 4. Design/conduct an experiment 5. Gather/analyze data information from an experiment 6. Form conclusion based on data and determine whether hypothesis was correct or incorrect with support data

  4. Experimental Process: Terms of recognition What is an experiment? • An experiment is a test between two or more “groups” • Series of ordered (numbered) steps to test a hypothesis • Terms: 1. Experimental Group • group used to test the hypothesis (changes) 2. Control Group • group which is given “normal” conditions (no change) 3. Variable • the thing that is different between the experimental and control groups – independent and dependent

  5. Which plant is the control group and which plant is the experimental group? Experimental Control

  6. What are the variables for the experimental group? • Independent Variable – changes • sunlight • Dependent Variable – result of the change and what is being measured • Height of the plant • Color of the plant • Etc.

  7. *A THEORY IS A WELL TESTED HYPOTHESIS THAT IS BELIEVED AND ACCEPTED BY SCIENTISTS

  8. Problem A suggested solution to the problem Gathering

  9. How can we test these? Eating chocolate causes zits. Shaving make hair grow back more. Drinking coffee will stunt your growth. The full moon makes people restless. Reading in dim light damages a person’s eyes.
