Electricity - Tips & Tricks

ELECTRICITY TIPS & TRICKS

Electricity is one of the poorer performing topics for most students in P5 & 6. It is a very matter of fact topic which a lot of students JUST CANNOT REMEMBER.

As such, the best way for students to remember is by using stories to illustrate the concepts.

Let me just illustrate 1 important segment of electricity which most students cannot catch - concept on parallel and series arrangement.

Take the head of the girl and boy as light bulbs.
 







 Take the battery = power supply = chef which supplies 1 plate of sushi each time


The wires will just act as the conveyor belt.


So for the situation below, the loving boyfriend and girlfriend will sit beside each other and share the plate of sushi, so each person gets ½ the sushi:


When a boyfriend quarrels with the girlfriend, what happens now? They seat on separate seats, like the situation below:

Do you think they would want to share their sushi now?

NO! of course not! So they would get one sushi each. The different colour shows different pathway.





Test it out on an actual question now!




Arrange the four circuits, A, B, C and D in order, from the brightest bulb to the dimmest bulb.

TEST IT OUT: Calculate the units (sushi) received by each bulb (person)! ***Another tip: cover the components (batteries & bulbs) arranged in parallel.



Ans: D, B, A, C


Here’s a recent notes (S3) created with the students based on TYPES OF QUESTIONS & keywords to apply (also known as SECRET SUCCESS STRATEGIES, S3), well loved by parents and students. 

 It is not just a summary of the concepts but rather, function like a cheat sheet. The secret to this piece of notes is not what you see, its the process of creating it, the thought process translated to her that makes the difference.

Answers to PSLE Questions

Why do I write suggested solutions to Red Swastika 2018 SA1 Paper? - My students found it useful and requested for more!  - The parents who used it to help their child have found it useful!  That's why despite using 4 hours just to write ONE SET of the suggested solutions (Section B only) and doing the miscellaneous admin such as scanning, downloading documents, writing email to send out to our ISUN warriors, I do it.  Hope that all these will contribute to their learning :)  From the paper, there are quite a couple of questions from the PSLE Booklet: You can download the Red Swastika 2018 Paper here!  Red Swastika 2018 Q 30 Reproduction of Plants PSLE 2018 Q15 TEST IT OUT!  PSLE 2018 Q15 ANSWER  Red Swastika 2018 Q33 Adaptations PSLE 2013/ Specimen Paper Adaptions TEST IT OUT!  PSLE 2013/ Specimen Paper Adaptions ANSWERS Refer to other posts to learn more!

Respiration and Photosynthesis

By
Respiration and Photosynthesis With air quality going downhill, there may be chances that we need to carry plants around as our oxygen tank.  The working mechanism is based on 2 simple concepts of Primary 5 Science, Respiration and Photosynthesis.  As seen from the picture, the man is wearing a mask connected to the plant. As the man respires, it gives out carbon dioxide.  The carbon dioxide, together with water and light, the green plant with cholorphyll photosynthesises and produces oxygen for the man to respire and survive.   A summary of the both respiration and photosynthesis processes are below: Respiration Respiration is the breaking down of digested food with oxygen to produce energy. The equation of Respiration Sugar (from digested food) +  Oxygen (from inhaled air)   รจ  ENERGY (for body to use) +  Carbon Dioxide (to exhaled air) + Water Vapour (to exhaled air)  *NOTE* All living things respire including plants. Respiration takes place ALL the

Amazing Animals' Adaptations 2: The Light of Death

By
From the land, let's move on to the pitch dark sea. In the dark, many water creatures seek out for the light. However, unbeknown to them, they are courting their own death. Let's take a closer look at this deep sea angler fish. You may find it familiar as you may have seen from the movie, Finding Nemo. Anglerfish Adaptations: Light-emitting structure - Structural adaptation to attract prey so as to catch it Waving light-emitting structure - Behavioural adaptation to attract prey so as to catch it Many sharp jagged-teeth that are angled inwards - Structural adaptation to catch hold of prey easily and preventing them from escaping   ¹   Extended jawline - Structural adaptation to swallow prey easily Expandable Stomach - Structural adaptation to feed on prey bigger than itself and stock up food in the food-scare dark waters  ¹ Special sense organ  - Structural adaptation to look for mate and reproduce Male anglerfish attach himself to female anglerfish: Behavi
