Part One: Student Presentations
Since we ended up only having enough
time for each group to complete two of the
stations, each group will spend 5 minutes
explaining one of the two worksheets they
completed to the other two groups. Make
sure you use their presentation to help
you complete the one worksheet/station you
didn't get to.
Part Two: Experiment
Now we'll hook up a TI-82 to the
overhead projector unit and look at one of
the plots from the first day of class.
We'll take a volunteer up to the front of
the room, and that person will move in a
way that recreates the plot. Next we'll
look at the projection up on the board and
work together to draw the derivative.
Then let's have the calculator plot
velocity vs. time and see how that relates
to the picture of the derivative we have
drawn on the board.
How can we use this information to
figure out when we will have a postive
velocity? Negative? Zero? Can we somehow
draw a relationship between velocity and
accleration using the same kind of
thinking?
