<p> Catapults & the Scientific Process Observations:</p><p>What data can you collect that may show a mathematical relationship?</p><p>Round 1: </p><p>IV (Independent variable): The factor you want to control/change.</p><p>DV (Dependent variable): The variable that may respond to your independent variable.</p><p>Hypothesis:</p><p>Constants: The factors/variables you keep the same during the experiment.</p><p>Experimental Procedures:</p><p>______Data Table</p><p>Distance traveled ( ) Load 1 2 3 4 5 6 7 8 9 10 Mass </p><p>Qualitative Observations: Place to note trials that have errors. Round 2: </p><p>IV (Independent variable): The factor you want to control/change.</p><p>DV (Dependent variable): The variable that may respond to your independent variable.</p><p>Hypothesis:</p><p>Constants: The factors/variables you keep the same during the experiment.</p><p>Experimental Procedures:</p><p>______Data Table</p><p>Distance traveled ( ) Lever 1 2 3 4 5 6 7 8 9 10 Length </p><p>Qualitative Observations: Place to note trials that have errors. Analyzing data: GRAPH EACH OF THE ROUNDS ON DIFFERENT GRAPHS.</p><p>Graph your data using the following graphing criteria:  On graph paper  Title at the top (DV versus IV)  Graph takes up most of page.  X axis labeled with the IV (independent variable)  Levels/types of the IV identified on axis & evenly spaced if appropriate.  Y axis labeled with the DV (dependent variable)  Numbers along the Y axis evenly spaced.</p><p>Conclusions: In paragraph form answer the following.  Describe whether each of your hypothesis was supported or rejected by your data.  Give a 1 sentence summary of how you tested your hypothesis.  Describe your graphs as either linear or non-linear.  Provide a reason for the results you saw.  Explain any errors/difficulties you had during your experiment.</p>
