09-17-13 Hypothesis and Title

  1. 1. DEVELOPING A HYPOTHESIS AND TITLE FOR YOUR EXPERIMENT
  2. 2. SCIENTIFIC METHOD 1. Formulate a question. 2. Research the question. 3. Form a hypothesis. 4. Conduct an experiment to test your hypothesis. 5. Analyze data. 6. Draw Conclusions. 7. Communicate results.
  3. 3. THE FOUNDATION OF THE EXPERIMENT The development of a hypothesis is the first step in designing and conducting an experiment. The hypothesis should be: clear,  specific, and testable.
  4. 4. THE HYPOTHESIS… Is the prediction for the outcome of the experiment. States the relationship between the independent and dependent variable!
  5. 5. FORMAT  If the (independent variable) is (describe change)  Then the (dependent variable) will (describe change)
  6. 6. A SCENARIO Mr. Joralemon tested to see if the amount of TV had an effect on how many times a baby wakes up during the night He had his niece watch 1 hr, 2 hrs, 3 hrs, and 4 hrs of TV
  7. 7. THE EXPERIMENT IV: TV Time (1 hr, 2 hr, 3 hr, 4 hr) DV: How many times his niece woke up during the night Hypothesis: If the (amount of TV time) is (increased), then the (amount of times the baby wakes up during the night) will (increase)
  8. 8. THE HYPOTHESIS Hypothesis: If the (amount of TV time) is (increased), then the (amount of times the baby wakes up during the night) will (increase) This hypothesis states the relationship between the amount of TV time (IV) and the # of times the baby wakes up (DV)
  9. 9. EXPERIMENT TITLE Like your hypothesis, you also use a specific format on the title of your experiment Your title also shows the relationship between the IV and DV
  10. 10. THE TITLE OF YOUR EXPERIMENT… Is written in the following format: “The Effect of (Independent Variable) on the (Dependent Variable).” Remember, in your experiment, you are looking to see if the IV has an effect on the DV
  11. 11. A SCENARIO Mr. Joralemon tested to see if the amount of TV had an effect on how many times a baby wakes up during the night He had his niece watch 1 hr, 2 hrs, 3 hrs, and 4 hrs of TV
  12. 12. THE TITLE The Effect of (the Amount of TV Time) on the (Number of times the Baby Wakes Up During the Night).” Remember, in your experiment, you are looking to see if the IV has an effect on the DV
  13. 13. EFFECT VS AFFECT Effect is a noun. It refers to the outcome of an experiment. It is ALWAYS used when writing Titles. Affect is a verb. It means “to influence or act upon something.”
  14. 14. SOME PRACTICE 1. Each group must give each student in the group a specific number of 1-4. 2. I will put a scenario up on the screen. 3. Each group will discuss the scenario with each other and identify your variables. 4. I will then call out a student number and a question for you to answer. That student must write down the answer though the teammates can help. 5. I will call a team at random and check to see if you got it!
  15. 15. SCENARIO 1 Mayor Bloomberg set up an experiment to see if the amount of sleep affects the reading scores of 4th graders
  16. 16. SCENARIO 2 Justin Bieber beliebes that all of his tattoos will make girls more attracted to him He decides to test if the number of tattoos has an effect on how many girls approach him over the course of a year.
  17. 17. SCENARIO 3  Sidney Crosby set up an experiment to determine if the weight of a hockey puck has an effect on the speed of his slapshot. He measured his shot in mph.
  18. 18. SCENARIO 4  Dr. Frankenstein set up an experiment to see if the amount of time student spend on homework each night had an effect on their Science Regents Score
