  1. Homeroom Warm Up8-18-15 On this day in 1934, baseball great Roberto Clemente was born. Baseball is considered “America’s Pastime.” When you are outside of school, what is your favorite pastime and why?

  2. Academic Enrichment Closure8-18-15 Mia has a glass of water. Which of the following tools could she use to measure the amount of time it takes her to drink the water in the glass? • Graduated cylinder • Balance • Stop watch • Thermometer

  3. Science Warm Up8-18-15 In Josh's experiment, one step of the procedure requires him to bring some water to a boil. Which two pieces of equipment should Josh use to carry out this step? • a magnet and a petri dish • a magnifying glass and a test tube C. a bunsen burner and a balance D. a hot plate and a beaker

  4. Don’t ForgetHomework is due tomorrow Textbook page 35 #1-11

  5. GLE GLE 0707.Inq.1 Design and conduct open-ended scientific investigations. GLE 0707.Inq.5 Communicate scientific understanding using descriptions, explanations, and models.

  6. Steps of the Scientific Method

  7. The Scientific Methodinvolves a series of steps that are used to investigate a natural occurrence.

  8. We shall take a closer look at these steps and the terminology you will need to understand before you start a science project.

  9. Scientific Method 1. Problem/Question 2. Observation/Research 3.Formulate a Hypothesis 4.Experiment 5. Collect and Analyze Results 6. Conclusion 7. Communicate the Results

  10. Steps of the Scientific Method 1. Problem/Question: Develop a question or problem that can be solved through experimentation.

  11. Steps of the Scientific Method 2. Observation/Research: Make observations and research your topic of interest.

  12. Do you remember the next step?

  13. Steps of the Scientific Method 3. Formulate a Hypothesis: Predict a possible answer to the problem or question. Example: If soil temperatures rise, then plant growth will increase.

  14. Steps of the Scientific Method 4. Experiment: Develop and follow a procedure. Include a detailed materials list. The outcome must be measurable (quantifiable).

  15. Steps of the Scientific Method 5. Collect and Analyze Results: Modify the procedure if needed. Confirm the results by retesting. Include tables, graphs, and photographs.

  16. Steps of the Scientific Method 6. Conclusion: Include a statement that accepts or rejects the hypothesis. Make recommendations for further study and possible improvements to the procedure.

  17. Steps of the Scientific Method 7. Communicate the Results: Be prepared to present the project to an audience. Expect questions from the audience.

  18. Think you can name all seven steps? Collect and Analyze Results Formulate a Hypothesis Communicate the Results Observation/Research Problem/Question Experiment Conclusion

  19. Hypothesis The hypothesis is an educated guess about the relationship between the independent and dependent variables. Note: These variables will be defined in the next few slides.

  20. Do you know the difference between the independent and dependent variables?

  21. Independent Variable The independent, or manipulated variable, is a factor that’s intentionally varied by the experimenter. John is going to use 25g., 50g., 100g., 250g., 500g. of sugar in his experiment.

  22. Dependent Variable The dependent, or responding variable, is the factor that may change as a result of changes made in the independent variable. In this case, it would be the size of the loaf of bread.

  23. Control Group In a scientific experiment, the control is the group that serves as the standard of comparison. The control group may be a “no treatment" or an “experimenter selected” group.

  24. Observe your world and come up with a question to answer using the Scientific Method!

  25. Closure8-18-15 A good question to use for a scientific investigation should be testable, and it should be connected to science concepts. Casey wants to do a scientific investigation about light. Which of the following questions would be best to use to guide his scientific investigation? a. Which type of light bulb burns the longest? b. Which type of light bulb is preferred by moms? c. Which type of light bulb is easiest to catch? d. What color of light is the prettiest?
