PSLE Science: why “more coils” is marked wrong (electromagnet)

A Primary 4 question that catches Primary 6 students — and teachers. The question gives you an electromagnet: a rod, a coil of wire, and two batteries, lifting an object hanging on a spring. It asks for one change that makes the object move up more. Two answers are accepted: increase the number of batteries, […]

How to add fractions: Make the Same

How to add two fractions with different denominators, the way we teach it at LevelUp. 1/2 + 1/3: halves and thirds are different-sized slices, so they can't be added yet. We Make the Same: make 2 and 3 the same, which is 6. Whatever you do to the denominator, do the same to the numerator, […]

PSLE Science: Length Of A Spring Is NOT The Extension Of A Spring

Spring questions catch out more children than almost anything else in PSLE Science, and usually it is not the physics that does it. It is one word. A spring has a length before any load is hung on it. Add a load and it gets longer — but the extension is only the amount it […]

PSLE Science: What The Brown Dots Under A Fern Leaf Actually Are

Turn over a fern leaf and you will find rows of little dots. They are spore bags, and they are the whole answer to a PSLE Science question that catches children out: not every plant reproduces by seeds. In this clip: where the spore bags sit, how to tell a ripe one from an unripe […]

PSLE Science: these pink parts are NOT petals??

The bright pink parts of a bougainvillea are special leaves, not petals. The real flower is the tiny cream one in the middle, and inside it you can see the yellow anthers. In PSLE, if a question shows you a bougainvillea, find the real flower first. Book a trial class or WhatsApp us at 9826 […]
