3. Test your hypothes<strong>is</strong>: Select a jacket material by clicking the Wool, Nylon, or Denim button. <strong>The</strong>n drag adifferent colored jacket into each <strong>of</strong> the <strong>experiment</strong> boxes. A temperature probe will automatically beplaced in the pocket <strong>of</strong> each jacket. Click the Test button to start the <strong>experiment</strong>. When the timer stops,calculate the average temperature for each color <strong>of</strong> jacket (add the three temperature values together, thendivide the sum you get by 3), and record these averages in the Table area provided in the animation (lookat the bottom left‐hand side).4. Repeat the <strong>experiment</strong> and test a different jacket material or color.5. Analyze your data: Analyze the data in the Table. Click the Graph button to see your results graphed.6. Explain any patterns you observed. (Do NOT type your answers here. Type them into the appropriatewindow <strong>of</strong> the COAT LAB assignment online in WebStudy.)7. Draw a conclusion about how color affects heat absorption(Do NOT type your answers here. Type them intothe appropriate window <strong>of</strong> the COAT LAB assignment online in WebStudy.)Did your data support your hypothes<strong>is</strong>? Why or why not?<strong>How</strong> does the material <strong>of</strong> the jacket affect heat absorption?Describe the strengths and weaknesses <strong>of</strong> the computer model you used in the <strong>experiment</strong>.What other parameters could you use in such an <strong>experiment</strong> to determine the effect <strong>of</strong> color on heatabsorption?
