For my science fair project, I am trying to see how heart rate differs when fear strikes between the sexes. I am also looking to see how the "fight or flight" response differs from males and females.
 * Science Graphs **
 * 1) Write a description of the data you are collecting for your science fair topic.

2. What type of graph will you create? I will use a line graph to chart the heart rate and will use a tally chart to record how males and females respond to the fight or flight response.

3. Explain why you will use that type of graph. I will use a line graph for the heart rate because it will be able to better show how the heart rate changes among different sexes. I will use the tally chart to record the fight or flight response because it will allow me to show and record which sex more frequently "fights" and which sex more frequently " flees " from the source of fear.
