  1. Scientific Inquiry Notes about Controls, Constants, and Conclusions

  2. Warm up Question • What is the difference between a control and a constant? • A constant is something that stays the same throughout the lab. • The control group is the part of the lab that we use to compare our results to! No changes are made to the control in the lab! (Usually the original) • Why is the control important in a lab? • It allows us to compare the variables in the lab!

  3. Air Freshener Experiment #4 I see a commercial on T.V. that claims this product removes bad odors better than any other. I decide to try the product and see if it really works on bad odors. For the first week I use Febreeze, for the second I use Oust, for the third week I use Glade plug-in and for the fourth week, unfortunately I use nothing.

  4. The Stink- Eliminator Experiment • The independent variable- Different types of air freshener • The dependent variable- the amount of odor removed • A problem question/statement- What is the effect of the different types of air freshener on the amount of odor removed? • A hypothesis- If the air freshener used is Febreeze then the amount of odor removed will increase. 5. Control group- No air freshener

  5. Warm up Question • What is the difference between a control and a constant? • Please give an example of each from the different labs we did in class. (Airplane, pepper, dog bones, baking pans)

  6. Writing a conclusion to an experiment… A conclusion is how you will share the overall results of your experiment. Every conclusion needs to have the following FIVE items… • The PURPOSE of the experiment • The HYPOTHESIS • What the data showed (results statement) • Data (numbers) to support the results statement. (use at least 3 examples) 5. If the data supported, did not support, or was not clear about the hypothesis.

  7. Writing a PURPOSE… Use the formula: The purpose of the experiment was to determine the effect of the (I.V.) on the (D.V.).

  8. Writing a conclusion to an experiment… A conclusion is how you will share the overall results of your experiment. Every conclusion needs to have the following FIVE items… • The PURPOSE of the experiment • The HYPOTHESIS • What the data showed (results statement) • Data (numbers) to support the results statement. (use at least 3 examples) 5. If the data supported, did not support, or was not clear about the hypothesis.

  9. Breakfast Lab Write a conclusion for the Breakfast Lab using this data. I.V. types of breakfast D.V. test scores

  10. Breakfast Conclusion The purpose of this experiment was to determine the effect of the different types of breakfasts on the test scores. My hypothesis was that if I eat a healthy breakfast then my test scores will increase. The students who ate a healthy breakfast scored the best. The data showed that with no breakfast the test scores averaged a 72%, but with a healthy breakfast test scores averaged a 94.5%. The data did support my hypothesis.

  11. Flatulence Experiment The crazy science department wanted to see what types of food would make them the most gassy. First they tried bake beans. The next day they tried broccoli. The following day they tried cabbage. They also took data without eating any food.

  12. YOUR MISSION….. For each of the following experiments write: • The independent variable • The dependent variable • A problem question • A hypothesis 5. Control group

  13. The Data(copy this down)

  14. Flatulence Experiment • IV- The type of food eaten • DV- The amount of Flatulence • Problem Question- What is the effect of the type of food eaten on the amount of Flatulence ? • Hypothesis- If the type of food eaten is baked beans then the amount of Flatulence will increase. • Control Group- No food

  15. YOUR MISSION…. Write the conclusion for the Flatulence experiment. Every conclusion needs to have the following FIVE items… • The PURPOSE of the experiment • The HYPOTHESIS • What the data showed (results statement) • Data (numbers) to support the results statement. Remember to use two examples. Maximum and minimum. 5. If the data supported, did not support, or was not clear about the hypothesis.
