    Intro to ecology and the scientific method Intro to ecology and the scientific method Presentation Transcript

    • Ecology Mr. Nettles
    • Class Motto
      • Discipline fuels character!
      • Character builds hope!
      • Hope assures your future!
    • Agenda- Friday, January 6, 2011
      • Warm Up
      • What is Ecology?
      • Biomes Video
      • Exploring Ecuadorian Ecology
      • Wrap Up (LIA)
    • Today’s Objectives
      • I will explore different aspects of ecology?
      • I will understand the steps involved in the scientific method.
      • I will define ecology, hypothesis, quantitative, qualitative, independent variable, dependent variable, and control.
    • Warm Up
      • What do you know about ecology?
      • How is ecology used in our everyday world?
            • Use the internet to search the word “Ecology” to help you answer the warm up questions.
    • What is Ecology?
      • Eco = nature, environment
      • logy = “the study of”
      • Eco + logy = Ecology
      • the study of the relationships that living organisms have with each other and their natural environment
    • Wrap Up (Jan. 6)
      • What was one fact that you Learned today?
      • What was the most Interesting thing about today’s class?

    • Ecology Mr. Nettles
    • Class Motto
      • Discipline fuels character!
      • Character builds hope!
      • Hope assures your future!
    • Agenda- Thurs., January 12, 2011
      • Warm Up
      • The Scientific Method
      • Should My Friend Date Taylor Swift?
      • Wrap Up (LIA)
    • Today’s Objectives
      • I will understand the steps involved in the scientific method.
      • I will define hypothesis, quantitative, qualitative, independent variable, dependent variable, and control.
    • Warm Up (Jan. 12)
      • What are the four essential elements of ecological life that you learned from the short film last week?
      • Define Ecology.
    • Warm Up (Jan. 12)
      • Water, Nutrients, Energy, and Appropriate Temperature.
      • Ecology is the study of the relationships that living organisms have with each other and their natural environment.
    • Steps of the Scientific Method
      • The Scientific Method is a series of steps that scientists agree are a logical way to perform an experiment.
      • State the Problem or Question
      • Make Observations or Do Research
      • Form a Hypothesis
      • Test your Hypothesis or Experiment
      • Collect and Analyze Results
      • State your Conclusion
      • Communicate the Results
      Scientific Method
    • Steps of the Scientific Method
      • 1. State the Problem : Develop a question or problem that can be solved through experimentation.
    • Steps of the Scientific Method
      • 2. Make Observations or Do Research : Get information. Gather the “411”.
    • Key Points for Making Observations
      • Observations are made with your five senses: sight, taste, hear, touch, smell.
      • Observations are Quantitative if they use numbers and Qualitative if they use descriptions.
      • Observations are made while you are gathering information
    • Critical Thinking Example
      • PROBLEM: Why are students always late to class?
      • What is a quantitative observation for this situation?
      • What is a qualitative observation for this situation?
    • Steps of the Scientific Method
      • 3. Form a Hypothesis : Predict a possible answer to the problem or question. This is usually written as a statement.
      • Example: If soil temperatures rise, then plant growth will increase.
    • Key Points for Forming a Hypothesis
      • The hypothesis is an educated guess about the relationship between the independent and dependent variables.
      • A hypothesis is usually written as an IF/THEN statement.
    • Steps of the Scientific Method
      • 4. Test you Hypothesis or Experiment : Develop and follow a procedure to test your hypothesis .
      • Include a detailed materials list.
      • The outcome must be measurable (quantifiable).
    • What is Variable?
      • A VARIABLE is a factor in an experiment that can change.
      • There are two types of variables in an experiment: INDEPENDENT variable and the DEPENDENT variable.
    • Independent Variable
      • The independent or manipulating variable is the factor that is intentionally changed by the person doing the experiment.
    • Dependent Variable
      • The dependent or responding variable is the factor that may change because of changes made to the independent variable.
    • Controls or Constants
      • CONTROLS or CONSTANTS are factors that scientists purposely keep the SAME in an experiment.
      • The purpose of a control is to ELIMINATE OUTSIDE FACTORS that may throw off the experiment.
    • 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.
    • Steps of the Scientific Method
      • 6. State your Conclusion : Include a statement that accepts or rejects the hypothesis.
      • Make recommendations for further study and possible improvements to the procedure.
    • Steps of the Scientific Method
      • 7. Communicate the Results : Be prepared to present the project to an audience.
      • Expect questions from the audience.
    • SHOULD MY FRIEND DATE TAYLOR SWIFT?
      • Using the Scientific Method…
      • What’s the first step?
    • Step 1: State the Problem or Question!
      • Should my friend date Taylor Swift?
      • Next step?
    • Step 2: Make Observations or Do Research
      • PROS:
      • Pretty
      • Has a lot of money
      • Grammy-award winning artist
      • Lives in Nashville
      • CONS:
      • May be in a relationship
      • She may think he is stalker
    • Step 3: Write a hypothesis.
      • If my friend dates Taylor Swift, then he will be happier! (and so will she) 
    • Step 4: Test your Hypothesis or Experiment
      • Independent Variable: Dating Taylor
      • Dependent Variable: How much happier my friend gets than if he didn’t date her
      • Control: Not going on a date with Taylor
      • Variable: Date with Taylor
    • Step 5: Collect and Analyze Results
      • Measure his happiness from the control. (No date with Taylor)
      • Measure his happiness from the variable. (Date with Taylor doing the same thing he was doing alone)
      • Compare happiness.
    • Step 6: State your conclusion.
      • If my friend dates Taylor Swift then he will be happier! (and so will she)
      • CONFIRMED!
    • Step 7: Communicate the Results
      • BRAG about your date with Taylor Swift to your friends!
    • Wrap Up (Jan. 12)
      • What was one fact that you Learned today?
      • What was the most Interesting thing about today’s class?
      • How can you Apply or use the information that you learned today?
    • Ecology Mr. Nettles
    • Class Motto

      • Character builds hope!
      • Hope assures your future!
    • Agenda- Tues., January 17, 2011
      • Warm Up
      • The Mindset of a Scientist
    • Warm Up
      • What are the 7 steps of the scientific method?
      • What is a quantitative observation?
      • What is a qualitative observation?
    • “ The Mindset of a Scientist”
    • Instructions:
      • Form teams of two and brainstorm about a topic you want to explore.
          • The topic can be related to sports, movies, politics, food, a job you desire, etc.
      • State a problem related to your topic.
      • Use the internet to research 7 quantitative and 7 qualitative observations about your topic.
    • Instructions:
      • Form a hypothesis related to your topic.
      • Start the process of setting up an experiment to test your hypothesis.
          • You need to indentify the independent variable, the dependent variable, and at least 5 controls (including the purpose of each).
