Graphing Shadow Ratios
Using the graphing Calculator to analyze
your data graphically
Enter the data into List 1 and List 2
View the plot
Go to the y= menu and try to find a line
of best fit
Using your line, determine the height of
a tower with a shadow length ____
Journal Entry 3
How was the ratio average you
calculated from part 1 related to the
graph you made in part 2?
What advantage does the graphical
representation have over the numerical
one from part 1?
Looking at other data sets
Enter the other data set information in
L3, L4, L5 and L6.
Plot the the data and determine their
lines of best fit.
Graph those lines on the same axis as
your other data set.
Journal Entry 4
How were the graphs of the data sets the
What generalizations can you make about the
shadow ratios to their graphs?
The other data sets were taken in the
afternoon (3:20pm) and the early morning
(8:20am), which was which?
How might the seasons affect the data set?
