Experimental design presentation

  1. 1. Scientific Inquiry & Experimental DesignHow do we solve problems in science?
  2. 2. The scientific method… State the problem Form a hypothesis Procedure Results ConclusionLet’s have a more in depth look at what scientist actually use and more scientific terminology.
  3. 3. Experimental Design vs. ScientificMethod Experimental Design Scientific Method  Research Question  State the problem  Formulating Hypothesis  Form a hypothesis  Careful Observation  Procedure  Data Gathering  Results  Analysis of Data  Conclusion  Identifying patterns in the data
  4. 4. Types of Experimental Design  Different research questions require different experimental designs.  Descriptive Investigations  Experimental Research Design
  5. 5. Descriptive Investigations An investigation used to explore questions in environmental conditions you cannot control.  Ex. Jane Goodall’s study of chimpanzees.  Picture hyperlinked to: www.janegoodall.org/media/videos A hypothesis is not required in these investigations.
  6. 6. Experimental Research Design Can be used when focused on a single variable. Conditions can be controlled. Determines the cause of a problem. Ex.: Thumb Wars
  7. 7. Experimental Research Design:Thumb Wars 1. Research Question 2. Hypothesis 3. Gathering Data 4. Data Analysis  Patterns in the data 6. One variable tested: thumb length
  8. 8. Experimental Research DesignResearch Question: Do plants grow better in coke or water?
  9. 9. Do plants grow better in coke or water? Research Question: Do plants grow better in coke or water? Hypothesis Ex: Plants will grow better in water because plants need water to live. Gathering Data: Controlled experiment with one independent variable.  Independent Variable: Type of liquid given to plants  Dependent Variable: Measured growth of each plant  Constants: Conditions kept the same (such as amount of liquid, type of plant, soil, amount of sunlight)
  10. 10. Do plants grow better in coke or water?(cont.) Analysis of Data : Using graphs/tables to find trends in the data.
