Science
Toby tried to make invisible ink, which introduced him to the idea that some substances can become difficult to see under particular conditions. He engaged in practical investigation by attempting a process rather than only reading about it. The activity encouraged him to observe changes, consider possible causes, and recognise that scientific results may require testing and refinement. As a 14-year-old, Toby practised curiosity, prediction, and evidence-based thinking while exploring a simple chemistry-related question.
English
Toby’s attempt could be communicated through a short experimental record describing his method, observations, and outcome. Writing these details would help him use precise procedural language and distinguish between what he expected and what actually happened. He could also explain the result clearly for an audience who had not seen the activity. This supported scientific communication and reflective writing.
Mathematics
Although the activity did not explicitly involve mathematics, Toby could have applied measurement if he recorded quantities, timing, or the number of attempts used. Comparing results across trials would support organising data and identifying patterns. This would help him see how numerical evidence can strengthen conclusions from a practical investigation.
Tips
Tips: Turn Toby’s attempt into a fair investigation by having him test one safe, household method at a time while keeping the paper, writing tool, amount, and drying conditions consistent. Ask him to make a prediction, record observations in a table, and explain whether the evidence supported his prediction. He could compare how the message appears under normal light and a safe alternative viewing condition, without using heat or flames. Finish with a short reflection on how scientists improve procedures when an initial attempt does not work.

- The Boy Who Harnessed the Wind by William Kamkwamba and Bryan Mealer: A true story showing how curiosity, experimentation, and persistence can solve practical problems.
Learning Standards
- Science inquiry: Toby’s investigation aligned with observing, predicting, testing, recording evidence, and evaluating results, although the supplied standards list does not provide a specific Year 9 or Year 10 inquiry code.
- AC9E6LY01 – English: A written explanation of the procedure and result could involve evaluating language and multimodal features used to communicate information.
- AC9M6A02 – Mathematics: Recording unknown quantities or comparing measured results could support representing and solving problems involving variables.
