PSLE question_energy_2018_Q35 asked a question which everyone experiences in real life. In spite of that, it is difficult to explain.
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.
Gravitational potential energy experiment set allows students to investigate how mass and height affect the gravitational potential energy of the object.
This is an energy related question. When the balloon is totally deflated, it does not stop immediately. The elastic potential energy of the balloon converts totally to kinetic energy of car at position L. The car converts all its kinetic energy to heat and sound energy from L to M.
PSLE question_Force_2019 Q38 is difficult for the students to visualise especially when the attraction force in involved.
Many students cannot understand that the whee an attraction force is acting on a magnet which is placed on an electronic balance, the total force acting on the electronic balance decreases and hence the reading on the balance decreases.
PSLE 2018 Question 38 presents a practical 2-way switch which is commonly found at homes. This type of circuit is not usual in PSLE. Most students do not understand the 2-way switch circuit and the absent of a battery also post a problem to the candidates. We created an exact 2-way switch circuit here hopefully it is useful for the science teachers to show and explain.
PSLE 2017 Question 37 is not too difficult to answer but difficult to understand. The equipment sited in the question is difficult to visualise how it works.
We made a model to illustrate how it works. Hopefully is useful to the science teachers for them to explain.
Light experiment set - experiment 1 is an experiment created for 2014 PSLE Science Booklet A Question 30. Weaker students are not able to visualise the effect of changing the distance between light source, object and the screen on the size of the shadow. This set-up effectively helps these students understand the concept easily.
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.
Electric bell with wooden base is an application of electromagnet. It using an automatic switching
on and off system to make the striker hits the bell continuously.
This teaching aid is suitable for primary 6 (force) and sec 4 (electromagnetism).
This is a series of activities to understand light.
These activities are suitable for primary 4 (light).
Attached a Light Exploration Set worksheet for teachers to use during HBL. Please feel free to download.
