Joel Langlois, a student of John Childs (Grenville Christian College, Brockville, Ontario) walked away with "First Place -Best of Fair- Overall", and went on to the Canada Wide Science Fair in London, Ontario. Joel used one of our heart rate monitors to study the variability of heart rate among people.

There have been several articles in The Physics Teacher in which teachers use our computer software (usually Logger Pro) or calculator software to do experiments and demonstrations. You might want to check out the details in The Physics Teacher.

	Vol 37, Nov 1999, p. 496, The Energetics of a Bouncing Ball, by Warren A. Turner and Glenn W. Ellis (Brunswick School, Greenwich, CT). This is a great lab exercise where students graph kinetic, potential, and total energy as a ball bounces.
	Vol 37, Dec 1999, p. 551, Heating Water: Rate Correction Due to Newtonian Cooling, by James O’Connell (Frederick Community College, Frederick, MD). Students use Newton’s Law of Cooling to explain the non-linear rise in temperature as a container of water is heated.
	Vol 38, Jan 2000, p. 6, Decoding the TV Remote Control, by James O’Connell (Frederick Community College, Frederick, MD). Students use Logger Pro, a ULI, and a solar cell to study the pattern of infrared pulses from remote controls.
	Vol 38, March 2000, p. 176, Computer-Based Experiments to Measure RC, by Francis X. Hart (University of the South, Sewanee, TN). Students use our interfaces and our Instrumentation Amplifiers to study the charging and discharging of capacitors.
	Vol 38, Sept 2000, p. 354, Variations of a Circular-Motion Lab, by John L. Makous (Providence Day School, Charlotte, NC). A variation of the circular motion/centripetal force lab that uses a Dual-Range Force Sensor to monitor the force and provide a way of measuring the period.
	Vol 38, Sept 2000, p. 367, Improving Precision and Accuracy in the g Lab, Parker Moreland (Danbury, CT). This is a very nice study of the details involved in improving the measurement of g by using either picket fences or a pendulum. Included is a nice chart for estimating your local g from your latitude and elevation.
