In science, it’s always nice to be able to do a hands-on experiment. While there are many experiments you can do in class, there are some you can’t. Sometimes a particular experiment may require expensive equipment that you don’t have, may take too long to set up, may yield data that is too imprecise to analyze properly, or an experiment may be too dangerous for a classroom setting. At the latest annual OAPT conference Andrew Moffat showed us several websites with video libraries filled with experiments that I wouldn’t be able to recreate myself (skip to the end of this article for those links). To give you a taste of what kinds of videos are available, and how you might build a lesson around one of them for your students, I’d like to analyze one of my favourite videos from the collections.

A Practical Experiment For Learning Kinematics and Other STEM Concepts
Dr. Theresa Stotesbury, Research and Product Development, Trent University
I am part of a research group out of Trent University (Peterborough, Ontario) that has developed a teaching kit that provides a 60-minute problem-based experiment that is suitable for high school science students. The activity connects forensic science and kinematics through the analysis of blood spatter. I will be presenting the kit at the OAPT conference at 9:30 on Friday May 12th. Read More...

Fill a one-litre graduated cylinder with water; the cylinder should be about 5 to 8 cm in diameter and 30 to 40 cm tall. Take an ordinary glass marble and try to drop the marble into the water in such a way that the marble will fall all the way to the bottom without first hitting the side of the cylinder. The marble makes an audible click every time it hits the glass wall. Read More...

The heart is a mechanical pump that is used to move an incompressible fluid (i.e., blood) through a very elastic closed network of tubes. With each cycle of the “pump,” the whole system expands and contracts. Read More...
