Now that you have finished the three challenges, its time to analyze the data.

Graphs

Compare your graph with those of another group. Do they look like yours? They should, as long as you graphed the same information on the same day. If they are different, find out why?

Answer the following questions about the graphs:

•   Do you see a connection between the weather and the uv index?
•   Look at the days that you collected the stream flow data.  Compare this to the precipitaion for those days.  Do you see a connection?

You have now completed your journey.  Review your opening journal entry and answer the following questions.  To view the original journal questions from the Project Set Up page, click here.

Would you have chosen the same supplies?  Why?  Why not?
Would you have chosen the same clothing?
Were your predictions correct about the travel time?
Were your weather predictions correct?

Project Analysis

In your journal, write a closing paragraph describing the relationship between energy sources (water) and work output.  Refer to Challenges 1, 2, and 3 and reconsider the analysis of the assumed volume, speed, and depth of each river or body of water.  Include how this relates to the environment.
