Barb, ULI stands for Universal Lab Interface.  Using this device and its probes
 you can measure force with a force probe, light intensity with a light probe,
voltage with the voltage probe, and motion with a motion detector, etc.  What's
 really neat is when you combine the data collected through these probes with a
 spreadsheet!  I do a lab where the students apply force to a bow and measure t
he displacement in order to produce a F vs d graph, then utilize the work energ
y therom and their knowledge of projectile motion to predicte where the arrow w
ill land given a certian angle.  Normally this is done by hand and takes a larg
e amount of time.  I adapted the lab this summer for a ULI.  Using a force prob
e and a motion detector(this will give the student distance data) you can get n
early 200 data points!  By hand, the students usually get 7-10.  Using a spread
sheet the students can find the equation for the line and use their knowledge o
f caluclus to discover the work(in some cases, depending on the spreadsheet it
will even find the integral for them).  I plan on trying to use in  much more

this school year.  Sorry, if this was a bit long.  Kathy
