Knowing a scientific definition and using evidence to explain an unfamiliar situation are different skills. If you are preparing for John Monash Science School, make space for both. A useful practice session should leave you better able to interpret information, justify a conclusion and communicate its limitations.
The official JMSS FAQs include scientific aptitude and scientific writing among the assessment areas. The activities below are original study suggestions. They are not official JMSS questions, recalled examination material or predictions of the next test.
Start with a question, not a memorised answer
When you open a science problem, identify what it asks you to do. Describing a pattern, explaining a mechanism, comparing alternatives and evaluating an investigation require different answers. Underline the task word and briefly restate the problem in your own words.
Next, make a distinction between supplied information and knowledge you bring to the task. If a passage defines an unfamiliar process, use that definition consistently. If the data do not measure something, avoid writing as though they do. A convincing explanation depends on the connection between the evidence and the claim.
Read a graph in four passes
- Identify the variables. What changes, and what is measured?
- Check the scale and units. Notice intervals, starting values and whether the graph shows totals or rates.
- Describe the pattern. Identify increases, decreases, plateaus or unusual observations.
- Set a boundary. Decide which conclusions the information supports and which would require more evidence.
Try speaking your interpretation aloud before writing it. If you cannot explain what one point represents, pause before drawing a broad conclusion. Small misunderstandings about axes or units can affect every later step.
An original practice exercise: compare two paper helicopters
Hypothetical learning activity: A student compares two paper-helicopter designs dropped from the same height indoors. Design A remains airborne for 1.8, 2.0 and 1.9 seconds. Design B remains airborne for 2.2, 2.0 and 2.4 seconds. The student measures each flight with a handheld stopwatch. These invented results are provided for practice only.
Before reading the discussion, answer four questions:
- Calculate the mean flight time for each design.
- State one conclusion supported by these trials.
- Identify one limitation of the investigation.
- Suggest one improvement and explain why it would help.
The means are 1.9 seconds for A and 2.2 seconds for B. A careful conclusion is that B had a longer mean flight time in these trials. Saying that B will always stay airborne longer goes beyond the evidence: one B trial lasted 2.0 seconds, and there were only three trials per design.
A possible limitation is variation in manual stopwatch timing. Video recorded at a known frame rate could help measure the interval more consistently. Repeating the trials could provide a fuller picture of variation. Neither change automatically removes every source of error, so explain the particular problem your improvement addresses.
Now add a complication: the designs use different paper types as well as different rotor lengths. Can you conclude that rotor length caused the difference? You cannot isolate that factor from these results. A stronger follow-up comparison would keep the paper type the same while changing rotor length.
Build an explanation the reader can follow
For a short evidence-based response, try this practice scaffold:
- Claim: answer the question directly.
- Evidence: choose the relevant observation or calculation.
- Reasoning: explain how that evidence supports the answer.
- Qualification: identify a meaningful limit when needed.
For the helicopter exercise, you might write: “Design B had the longer average flight time in this investigation: 2.2 seconds compared with 1.9 seconds for A. This supports choosing B if mean airborne time is the priority under these conditions. More trials would help assess whether the difference is consistent.”
This is a learning scaffold, not a required JMSS response format. Adapt your structure to the actual task. A method, a comparison and an explanation for a younger reader should not all sound identical.
Practise communicating to a particular audience
Choose a concept from your school science lessons. Explain it first to a classmate, then to someone younger. Keep the underlying science accurate in both versions, but adjust the vocabulary and examples. Define a technical term when the reader needs it rather than adding terminology merely to sound advanced.
Check analogies carefully. An analogy can introduce an idea, but it may have limits. Ask yourself where the comparison stops being useful and whether your wording could create a misconception. Clear scientific writing makes the reader’s job easier without distorting the idea.
Review one weakness at a time
After writing, highlight your claim, evidence and explanation in different colours. If the whole paragraph is description, add the missing reasoning. If the paragraph contains several claims but little evidence, narrow its scope. If the science is sound but the sentences are difficult to follow, simplify the wording.
Keep a short revision record: original sentence, identified issue, improved sentence. Revisit the same skill with fresh material later. That makes feedback usable rather than something you read once and forget.
Choose resources with realistic expectations
Edutest’s practice-test information says its sets exclude written expression and science material. Use them within that scope; do not assume they cover every aspect of JMSS preparation. Edutest also withholds specific science-test details, so these exercises should build transferable skills rather than imitate a claimed secret format.
