To find a vector between two locations, simply subtract the coordinate of your second location from the coordinate of your first location.

For example, I figured out that Phoenix, AZ has coordinates of (-112, 33) and Grand Canyon has coordinates of (-112, 36). If I subtract my second coordinate from my first coordinate, I get:

(-112, 36)

– (-112, 33)

<0, 3>

So, that means that if I start out at my first coordinate (-112, 33) and add a vector of <0, 3>, then I will end up at (-112, 36), which is exactly what I want.

Continue doing this until you figure out the vector between each of your national parks. Make sure you figure the vectors out in the order you created them on your map. Fill in your form as you go.

When you are done completing your Vector WebQuest Form, take out a separate sheet of paper and do the following:

• On the first line, add your first and second vector.
• On the second line, add your result to your third vector.
• On the third line, add your result to your fourth vector.
• Continue doing this until you have added all your vectors.
• Write these questions out and answer them.
• What was your final result?
• Is it what you were expecting? Explain.

On your map:

• Label each national park with its proper coordinate.
• Label the lines connecting your national parks with the proper vector.

When all is done, I should be able to start at the coordinates of Phoenix, and add a vector that gets me to the next location, then add a vector that gets to the next location and so on and so on until I have made a complete circle.

Finally, turn in your WebQuest. Make sure you have your completed form, and fully labeled map.
