Science Lesson

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...

How stroking method works to magnetise a steel nail is not required in PSLE but important for O level. In recent years, PSLE did have few questions on this concept (with guidance). Since the concept is not too difficult to explain and understand, i would like to use Simple Dipole Model to briefly explain the concept...

PSLE 2014 Question 44 is difficult to visualise how it works. Many students who did not have a prior experience with this toy could not understand the question. We sourced for a similar toy to illustrate how it works. Hope this video will help the teachers to explain to the P6 kids...

PSLE question_energy_2018_Q35 asked a question which everyone experiences in real life. In spite of that, it is difficult to explain.

Many students may not be able to visualise the effect of having less mass (load) on the train and having a train moving up a slope.

A battery operated car is used to for the experiment.

The other day I was tasked to relief a Primary 5 electricity lesson on circuit card. To get over the trouble of preparing many circuir cards and after that have to disinfect them, i created a magnetic circuit card set. During the lesson i asked students to set questions for the whole class. The lesson was effective and efficient.

Difference between series and parallel circuit is very easy to show if you have the right equipment. The Series and parallel electrical circuit demo is able to show (1) the difference in brightness, (2) the independence of the parallel circuit.

Types of energy is made for the P6 students in Singapore for the science education. Hope through the various demonstrations using toys and teaching aids, students can understand the various forms of energy in greater depth. This was made for P6 students one day before Circuit Breaker 2020.
