I am using this post as a way to document my brief plans for tomorrow’s Google Meet lecture with the LOA students as well as to park the links to the resources and tools that I intend to use for… Continue Reading
This app is used to demonstrate how a spherical object with a finite volume immersed in a fluid experiences an upthrust due to the differences in pressure around it. Given that the centre of mass remains in the same position… Continue Reading
This Geogebra app allows students to explore how the position of the centre of gravity as well as the width of its base affect the stability of an object.
This video is taken during my IP4 class today. My students are making use of rubber tubes to demonstrate how we can use gravity to siphon water from one place to another. As long as the level of the source… Continue Reading
Here are two applets students may like to try: A. The first is a simple “experiment” showing that the extension of a spring is proportional to the force applied: http://www.absorblearning.com/media/attachment.action?quick=5l&att=394 B. For the second applet, you can try: looking for… Continue Reading
This demonstration can be modified for use as a magic trick. Materials: Glass of water Piece of cardboard that is larger than the mouth of the glass. Procedure: Fill the glass up with water. Place the piece of cardboard over… Continue Reading
This simple demonstration can be done anywhere at home using the following items: an empty glass a toothpick two forks The video below demonstrates how to do it. When the forks are balanced on the mouth of the glass with… Continue Reading
Ever wondered how a submarine sinks and floats? The demonstration here can be used to explain the changes in forces involved and is going to impress most people who see it for the first time. It consists of a floating… Continue Reading
