Learn & practise · P5, PSLE, Sec 1 and Sec 2 (G2)
One chapter, start to finish.
Every chapter goes the same way: try the idea in a lab, work through the quest, then practise writing the answer. Pick the P5, PSLE or Sec 1 (G2) track, then a chapter.

How every chapter goes
same three steps, every time
Try it in the lab
Read the chapter notes and open its lab. Predict a result, change one thing and see what happens.
Do the quest
Short stages, one idea each, then a timed Boss. Practise explaining the science and compare your reasoning with the model answer.
Come back to it
Use saved progress and revision notes to choose what to practise next. Guided Learn helps you revisit what you missed.
Look inside a chapter
Flip through the tabs. Everything here is a real screen or a real example. Sign in for the full chapter and saved progress.
Every chapter has a lab made of small stations. Build, adjust and try again: each change is a chance to ask what happened and why.




Answer Writing
where Booklet B marks are won
Practise reading the question, choosing an answer shape and explaining the science. For P5, this builds the skills Booklet B asks for.
Spot the question word: “state” asks for a fact, “explain” needs cause and effect, and “compare” needs both sides. Use the marks as a guide to how many separate points the answer needs.
Choose an answer pattern, then fill it in. Explain: answer → science idea → link to the observation. Compare: A … whereas B …. Predict: a prediction, because …. Using a graph: quote data, then state the trend. Fair test: what to change, measure and keep the same.
See the claim, the evidence from the question and the science reasoning as separate parts, so children understand why an answer scores.
Catch vague words such as “it”, missing explanation steps, one-sided comparisons, missing links to the question and unnecessary reasons when a question only asks children to “state”.
Type an answer in your own words and get instant feedback on earned mark points and missing parts. Live in the Circuit Lab today; coming to more chapters.

Colour-coded model answer
Explain why the bulb goes off.
ClaimThe bulb goes off.
EvidenceThe switch is open.
ReasoningThe circuit is incomplete, so electric current cannot flow through the bulb.
“It stops because it is broken” hides the science. Which word would you change?
A useful view for parents
