 * __Big Ideas:__** Many real world situations can be modeled an predicted using mathematics.


 * __EQ:__** What kinds of relationships make straight lines on a graph?


 * __Notes:__** None Taken


 * __1.1 Testing Paper bridges__

A.** Do the experimnt described above to find breaking weights for bridges 1, 2, 3, 4, and, 5 layers thick. ( Done In Class)
 * B.** Make a table and a graph of your data.

For layers 6 I perdict 55 pennies and for layers 7 I perdict 70 pennies. For 2.5 layers thick I predict 17 pennies and for 3.5 layers thick I predict 21 pennies.
 * C.** Describe the pattern of change in the data. Then, use the pattern to predict the breaking weights for bridges 6 and 7 layers thick.
 * D.** Suppose you could use half-layers of paper to build the bridges. What breaking weights would you predict for bridges 2.5 layers thick and 3.5 layers thick?


 * __Problem 1.1 Follow-Up__**

How would you expect your results to change if you used a stronger material, such as posteer board or balsa wood, to make your bridges? then it'll take moer pennies for the bridge to bend or crumple.
