### Practicing sceintific method

1. 1. Practicing Scientific Method
2. 2. Steps of the Scientific Method
3. 3. Components of Scientific Experiment  Title  Background information  Hypothesis  Materials  Controls & Variables  Procedure  Data & Analysis  Conclusion
4. 4. Variables  Variables are factors that change during experiment.  Independent Variable (IV): variable that is purposely changed during experiment  Dependent Variable (DV): variable that changes in response to purposeful change (IV)
5. 5.  Controls: Variable that all others will be compared to ◦ Allows variables to be compared to something  Procedure: step by step instructions of what you will do  Constant: Experimental aspect that is kept the same for all trials
6. 6.  Title of Experiment: ◦ The Effect of (Insert Independent Variable Here) on (Insert Dependent Variables Here).  Hypothesis of Experiment: ◦ If (planned change in independent variable), then (predicted changed in dependent variable) Or another way to look at it… ◦ If (I do this) , then (this) will happen.  Test your hypothesis by doing the experiment
7. 7. Example: Test insulation of different materials on jar of water  Title: The Effect of Type of Insulation Wrap on Temperature of Water in a Jar  Hypothesis: If jars of water in the sun are wrapped with different types of insulation, then the temperature of the water in the jars will increase by different amounts.  IV: Type of insulation  DV: Change in temperature of water in jar
8. 8. Collect Data Control IV 1 (Cotton) IV 2 (Wool) IV 3 (Nylon) Results of Trials (May be more than 1) Results of Trials (May be more than 1) Results of Trials (May be more than 1) Results of Trials (May be more than 1)
9. 9. Data & Results  Analyze your data: ◦ Qualitative (They’re hot!), Quantitative (They’re a 10!) ◦ Create a graph/chart  Conclusion: ◦ Briefly restate hypothesis ◦ Answer to your question ◦ Explain your results (How & Why) ◦ Describe any modifications and next steps.
10. 10. Practice Science Method 1. What is the independent variable? 2. What is the dependent variable? 3. What would be an appropriate control? 4. What are some of the constants? 5. Set up a graph (Title & Labels) for data A group of scientists want to measure the effect of adding different types of nutrients to the same plant species. They plan to add 3 different nutrients to the different species and measure the effect on the plant’s growth.
