Collect and Analyze Data While doing the experiment, we observe what happens and collect data. The data describe what happened in the experiment and is usually shown in charts, graphs, and tables. Cup type Thermos® Plastic Styrofoam Initial Temp 160 160 160 temp after 30 105 88 95 minutes temp after 60 92 74 84 minutes temp after 84 70 75 120 minutes Draw Conclusions Using our analyzed data, we now see if our hypothesis is right. The conclusion is our written statement that says what we think about our hypothesis. Scientists repeat their experiments many times to make sure their conclusions are right. My hypothesis is correct: The temperature in the Thermos® cup was the highest after 120 minutes, therefore a thermos cup is the best insulator. Communicate the Results Finally, we describe the research we have done, the hypothesis, the experiment, the data, and our analysis so we can share it with others. This is done through reports, oral presentations, and journal articles. This can give other scientists a chance to repeat the experiment and see if their results match. Science Experimental Design Practice 11 Questions you can turn into simple, low-cost experiments to experimental design: 1. Does adding aspirin to water keep flowers fresh longer? 2. How does the height from which a ping-pong ball is dropped affect the bounce height? 3. Which type of cup is a better insulator (Styrofoam, Thermos®, plastic, etc.)? Compare temperatures of hot water over time. 4. How does activity (lying, sitting, walking, running) affect pulse rate? 5. Which color of M&M’s will people choose from a bowl or will they care? (This requires you to have an even number of each color of M&M evenly mixed in the bowl and not to tell the test subjects what you’re testing.)
