But you cannot receive more than 40 points total for the two scientific inquiries. Please, hand in this worksheet with any accompanying graph(s) by Sunday Nov. 21, before 11:59pm. Please write in complete sentences. Write in your own words, not copying from the provided information or your partner! Remember academic honesty! 1. What do you want to know? Clearly state the research question being asked. [1pt] Would the average hit intensity affect the $100B levels Can the average hit intensity be used as an ator to accurate diagnose co cussions? Clearly state the hypothesis to be tested. [1 pt] Remember a hypothesis is not an if/then statement, and it is not a prediction! The severity of the average hit intensity will affect the $100B levels. What do you predict is the correlation between blood levels of the protein S100B and severity of the hits to the head? [1pt] I predict S 100B levels will increase as the average hit intensity increase. 2. Briefly explain the biological context for conducting the study. In other words: why is this important? What happens to the brain and the body with a concussion? What happens with a second concussion? [2 pts] 3. How was the study conducted? Briefly describe the experimental design. A person who was not in class, should be able to repeat the experiment by reading this section. [2pts] Page 1 of 5 657 words English (United States) Focus E + 86%A A ? C E AutoSave OFF ...

What were the dependent and independent variables? What controls were used and why? [2 pts] Y The dependent variable(s) is/are: _S100B levels._ X The independent variable(s) is/are: _ _Average hit intensity The controls are: _ _location of the game and helmet Why do we use controls in experiments? 5. What were the results? Graph the results on the provided graph paper. Make sure you do a scatter plot and a best-fit line. Attach graph to this sheet. Make sure the graph is clear and appropriately labeled. [3 pts] 6. State your results. State your results in one or two sentences. [1 pts] Explain your graph to someone who cannot see the graph. Be specific. 7. Discuss the results. Was your hypothesis supported or not? [1pt] 8. What type of correlation is shown in your scatter plot? [1 pt] Strong positive correlation 9. Describe how your results relate to your predictions, based on the biological context? In other words, why do you think the results turned out the way they did? [2pts] Remember the biology of the concussion and what is happening in the brain and body of the player. Page 1 of 5 657 words English (United States) Focus E + 90%A A ? C E AutoSave OFF ...

Discuss limitations of this experiment. Briefly explain how the study could be improved upon. Offer two suggestions to improve this study [1 pts] List two possible sources of error not including the two suggestions from above limitations. [1 pts] 11. How does S100B end up in the blood after a concussive hit to the head? Explain. [1 pts] 12. My prediction for this experiment is: The higher the hit intensity average, the more S100B level will be in the players blood. Are there any players who do not fit this prediction? How do you explain this? Why would someone with a lower hit intensity have a high $100B level after the game? [2 pts] Player 1 cuz although he had a low average hit intensity, he had a high $100b levels. Page 2 of 5 657 words English (United States Focus 87%A A ? C E AutoSave OFF ...
