Innovative Uses
Dewey Beadle (Seneca HS, Louisville, KY) has been using our Apple II products for many years. His students are still doing quality science experiments with the Apple IIs. Here are some sample graphs showing force vs. time for collisions between a cart and a mounted force sensor. The top graph is a collision with no padding and the bottom graph is a collision with a foam bumper.
Mary Pat Evans (The Londonerry School, Harrisburg, PA) sent us information about her 8th-grade student, Jessica Lyons, who recently entered a science fair with a project on monitoring the purring of cats. Jessica used a ULI and microphone. Her original hypothesis was that the volume would increase when the cat was petted. In fact, she discovered that the frequency of the purring also increases when the cat is petted.
Jerry Easdon (College of the Ozarks) and his student, Scott Deken, sent us data collected from a ride on the Ozark Mountain Skycoaster. The ride is like the giant swings you may have seen at other amusement parks. The graph above shows the total acceleration calculated as the vector sum of three accelerations measured with our 3-Axis Accelerometer (order code 3D-DIN).
