Penguins Lab Report In this experiment we will be investigating if the number of penguins in a huddle will affect the warmth of the penguins. Research Question: How does the amount of Emperor Penguins huddling in a group affect the amount of heat that is insulated? Hypothesis: I believe In this experiment, In a huddle, the number of penguins will most definitely affect the warmth. This is because with more penguins, there will be more people to move around and act as a “windbreaker”. Not only that, there will be more body heat radiating.

Independent Variable Huddle Number Dependent Variable Heat of “Penguins” in Celsius Controlled Variable Body Size. Insulation Thickness Variables: Materials: Beaker 17 Test Tubes Cotton Data Log/ Probes Pen and Paper Stopwatch Stand Method: 1. Heat water 2. Taking a cotton sheet, line the beaker with It, folding the excess cotton sheet OVER the edges. 3. Taking your 17 test tubes, put them all In the beaker 4. When water is heated, pour water into each test tube until each test tube is completely full 5.

Taking a stand, attach a probe that can record the temperature into ‘ Connect it to the computer and press start. 7. When 5 minutes is up, quickly proceed to take out eight test tubes from the beaker 8. When 10 minutes is up, quickly proceed to take out another eight test tubes 9. Leave the last single test tube in for another five minutes, and when fifteen minutes is up, stop the recording and clear up your workspace. Figure 1. Graph of our data Data Table: Time (sec) Temperature (Celsius) Number of test tubes 6 17 54. 5 51 . 9 45. 5 As seen above, the data results fall in temperature when they don’t move around and huddle together more. The temperature drops dramatically when test tubes are removed. In conclusion, my hypothesis was correct, whenever test tubes were removed from the beaker, the temperature would drop dramatically. The amount of emperor penguins effect the heat and the huddling as with more animals, there will be more bodyheat and more body heat equals more heat in general, keeping the penguins armer and more insulated this way.

Evaluation: Whenever test tubes are removed, the temperature would drop dramatically. A way to improve the experiment would have been to try not to get the cotton wet by pouring thewater more carefully so that it would insulate better. The data is accurate as there seem to be no large and strange changes within the graph. Another way to improve the data results is to do more tests and take the average and compare the data results so test would be proven fair.
