When compasses are placed together or with magnets, the polarity of the compass needle may be reversed due to the surrounding magnetic fields. The N-pole of the compass needle will hence points to the South instead of North. The video here teach you how to repair the compass needle. You will need a strong magnet to do the job. ..

Springs supported platform is fabricated to present PSLE 2016 Qns 44 clearly to the students.

It may be interesting to let the P6 students make their own spring balance after conducting the Hooke's law experiment. By doing so, the students can apply their knowledge of a extension spring into something useful.

Temperature and heat flow activity aims to help P4 students to understand that a few concepts about heat and temperature.

DIY friction exploration set investigates how the surface texture, wheels and weight affect the friction acting on an object.

Simple DIY electromagnet set consists of a 120 cm connecting wire and a steel bolt. Students can use the long connecting wire to coil around the steel bolt. As the number of coils increases, the magnetic force of the electromagnet increases.  The electromagnet is then connected to different number of batteries (in series). As the number of batteries increases, the magnetic force of the electromagnet increases. ..

A simple experiment to show the conversion of the potential energy of the spring to the kinetic energy of the car.

Many learners think that when an object become bigger, the mass (or weight) must also increase respectively. This video hopes to explain and show what happens to the object during heat expansion. It is the gaps between particles which have increased. There is no increase in particles during expansion via heating. ..

Here we want to introduce the "LENZ'S LAW ALUMINIUM PIPE EXHIBITION SET". This set is able to show the slow drop of a magnet is a tube which is made from electric conductor...

Expansion and contraction of solid experiment is to show that most solids will expand when they are heated and contract when their temperature decrease. This is similar to the ball and ring experiment.  ..

This blog shows the capability of "expansion and contraction of liquid and gas experiment". You do basically conduct 3 effective experiments to demonstrate the expansion and contraction of water and gas. ..

During circuit breaker 2020, I was force to conduct on-line lesson with the P6 kids. During a revision lesson on the comparison of brightness of the light bulbs. I created a simple electricity teaching aids to illustrate the various types of circuit. ..

In PSLE 2016, question 30 tested on extension springs with weights. In 2018, SEAB tested on the concept again but using compression springs. In this lesson, we set up the apparatus shown in PSLE 2018 question 26 and provide the explanation...

Force is a very abstract concept to our primary school kids. I personally think that our Singapore children are especially weak in understand force and energy because they are lacking experiences in hands-on activities. They games the play are mainly virtual and the housework is done mainly by the demestic helpers, parents and grand parents. I set up the experiment shown in the PSLE question and provide a simple explanation...
