Wait, What? A Science effect can begin before you can see it. A heater is switched on, but the thermometer does not jump immediately. A wilted plant is watered, but its leaves do not become firm at the exact instant the water touches the soil. A seed is placed in suitable conditions, but no shoot…

Learn how to compare PSLE Science investigations and decide which gives stronger evidence for a claim by checking fair-test quality, measurement relevance, repeats, specimens, range, controls and conclusion limits.

Learn how to read a PSLE Science graph with a non-zero or broken axis by recovering actual values and differences before judging the apparent size, slope or scientific importance of the change.

Learn to distinguish a PSLE Science data pattern from the causal mechanism that explains it, so trends become evidence rather than substitutes for scientific explanation.

Learn how to use PSLE Science diagrams and models as scientific representations—reading the relationships they encode, recognising simplifications and avoiding literal conclusions from size, colour, spacing or omitted detail.

Wait, What? Measuring more often does not automatically make a Science investigation better. If you measure a plant every ten seconds, almost every reading may look the same. If you measure cooling water only once at the beginning and once an hour later, you may miss the shape of the change completely. The useful question…
