This is an interesting question on electricity: in order to survive a lightning strike, which of the following costumes offer the best protection? A coat of armour, your birthday suit, a wetsuit or a superman costume? Watch this MinuteEarth video on Faraday's cage to find out!
Many a science teacher would have wanted to conduct a demonstration at the last minute but could not do so due to a lack of equipment or material. I have experienced that many times and even though I have many of these items hidden somewhere in some drawer, I can never seem to be able
I posed this question to the year 4 IP students as an introduction to the topic of heat capacity. For a more detailed look at how to conduct this demonstrations, visit http://www.scienses.com/heat-capacity-of-water-video/
I enjoy lecturing on topics like Superposition and Electromagnetism in the GCE A-level syllabus as they lend themselves well to the use of fun demonstrations that I can perform in front of the audience. One of the recent demonstrations that I did was to demonstrate the measurement of the magnetic force acting on a wire
It's about time Singapore considered building a liquid fluoride thorium reactor as a safe source of nuclear energy. From the video, it would appear that thorium is safe as it cannot be weaponized, does not require high pressure containers and the risk of a meltdown does not exist. For a small island state like Singapore,
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 is higher than the level of the receiving end, we can do so.
A disc rotates clockwise about its centre O until point P has moved to point Q, such that OP equals the length of the straight line PQ. What is the angular displacement of OQ relative to OP? A. B. C. D.
This question is meant for TA 2B and 2C Physics students. Other than the demonstrations we have tried out during class, could you think of any other way in which static electricity can be observed? Please leave your comments below. You may need to log in to Facebook while doing so.
For the topic of Thermal Physics, JC1 students can try to make sense of p-V diagrams using the following exercise, which does not involve any calculation. They will need to fill in the cells in the table below with any of the three (+, - or 0) to indicate whether there is heat transfer, work
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 the unknown masses. observing the potential energy at different extensions of each spring. varying the
