At the end of my first year teaching Physics at Crocus Plains I applied for CERN’s International High School Teacher Programme and became the first Canadian selected through direct entry in the 21 years of the program. I believe very strongly in showing students what Physics can look like and build lots of demonstrations and experiments for my classes to use, including a Reuben’s tube, an electromagnetic ring launcher, and Schlieren optics setup, just to name a few that have become fan favourites among the students in our building. Being in the vocational school for the region has led to many opportunities to collaborate with our Electronics, Design Drafting, Welding, and Photography departments on highly engaging inter-disciplinary projects. In 2018 I finally had the opportunity to once again teach Physics and have been working hard to build the program. In 2011 I moved back to Brandon, Manitoba and started working at the school I had graduated from, Crocus Plains Regional Secondary School. While there I also started a tremendously successful new course that gave students the ability to explore their interests in science and consisted of students completing one project a month, two of which were to be hands-on experiments, two of which were to be research based, and the final being up to the student. While teaching Physics there, I decided to invest in PASCO products and approached the Killarney Foundation with a proposal about funding the Physics lab with the SPARK Science Learning System and sensors. Having graduated with a major in Computer Science and minors in Physics and Mathematics, I began my teaching career at Killarney Collegiate Institute in Killarney, Manitoba in 2009.

Cars will withstand repeated drops to the floor.

Loss of energy due to friction is generally only about 5%.

Speed and height of the Roller Coaster car can be easily measured.

The PASCO Roller Coaster differs from conventional roller coaster toys in three ways: The whiteboard background is convenient for writing calculations or making marks for measuring heights. PASCO Advantage: The Roller Coaster can be configured in many ways. If the car is released from the top of the hill so it easily makes it over the top of the loop, the speed of the car can be measured at the top of the loop and the centripetal acceleration as well as the apparent weight (normal force) on the car can be calculated. Then the prediction can be tested on the roller coaster.

The height from which the car must be released from rest to just make it over the loop can be predicted from conservation of energy and the centripetal acceleration.

The total energy is calculated for two points on the track and compared. The potential energy is calculated from the measured height and the kinetic energy is calculated from the speed. The speed of the car is measured at various points along the track using a photogate connected to a Smart Timer. In this experiment, the Law of Conservation of Energy is verified by measuring the potential and kinetic energies of a car traveling over hills and loops on a curved track.Ī car is started from rest on a variety of tracks (hills, valleys, loops, straight track).
