An exciting scientific result is the beginning of a feasibility question.
Your challenge
Investigate a biotechnology, advanced-materials or energy concept using published sources and a safe model. Compare it with a simpler alternative.
LEARN & APPLY / 1
Understand the scale
Explain the system and relevant scale before using technical labels. Ratios, diagrams and models help distinguish a concept from an application. Define unfamiliar terms in your own words.
Try it yourself
Create an annotated diagram and explain three key terms.
LEARN & APPLY / 2
Check the evidence
Separate laboratory findings from field performance. Ask about the sample, conditions, replication and uncertainty. Trace claims to their sources and record what remains unknown.
Try it yourself
Compare two credible sources and their limitations.
LEARN & APPLY / 3
Ask whether it is feasible
Consider cost, manufacture, maintenance, environmental effects and the expertise needed. Introductory work uses models and published data, not unknown cultures, human samples or free nanopowders.
Try it yourself
Compare the concept with a simpler alternative and recommend a next research step.
WHAT YOU WILL BE ABLE TO DO
Distinguish a laboratory result from field readiness.
Compare lifetime costs, environmental effects and a simpler alternative.
WORKED EXAMPLE
See the thinking.
A new filter works under specified laboratory conditions. This does not establish performance with every local water source or make water safe to drink. Compare materials, maintenance, waste, expertise and the scope of the evidence.
RETRIEVE. EXPLAIN. CHECK.
What is a responsible next step after one promising laboratory result?
Write your own answer before opening the explanation. Then improve one sentence using what you learned.
Compare your reasoning
State the supported claim and limitations, examine replication and relevant conditions, and propose a safe investigation using published data or a model. Do not turn an early result into a public safety promise.
Stretch yourself
Create an evidence-versus-unknowns table and compare a lower-tech alternative across its whole lifetime.

Try before you read the solution.
The Researcher reads 'a material removed a pollutant in one lab test'. List two missing facts before recommending it for a community water system.
Scratch space: not saved. Copy useful reasoning into your private workbook.
Choose a fictional club service, a water-data investigation, or an accessible information tool as your capstone. Keep the same problem brief through your budget, prototype, tests, revision and final defence. The crew exercises teach a method; apply that method to your chosen project and explain any adaptation. Simulation is a complete route.

01 / PREDICT
How are watts and watt-hours different? Can a power rating alone tell us daily energy?
Write a prediction before you reveal the worked reasoning.
Your starter material
Fictional assumptions: panel power 100 W; four equivalent full-sun hours/day; system factor 0.75. A 10 W lamp runs for five hours. This is an educational model, not an installation or purchasing specification.
PRACTICAL STEP 1
Track units
Energy = power × time. Compute daily modelled supply and lamp demand. Explain that equivalent full-sun hours are a modelling input, not a promise of exactly four sunny clock-hours.
PRACTICAL STEP 2
Test uncertainty
Recalculate for two and six equivalent hours, then two lamps. List what the simple system factor hides: weather, losses, storage and ageing. Do not count the same loss twice.
PRACTICAL STEP 3
Compare a frontier idea
Compare the model with one materials or biotechnology idea from your mission. Use a claim/evidence/uncertainty table and a primary source. Choose what can be tested safely in a model rather than attempting unsupervised experiments.
Compare with the crew’s reasoning
Supply is 100×4×0.75=300 Wh/day. One lamp needs 10×5=50 Wh. The arithmetic leaves a nominal 250 Wh margin, but storage capacity, peak demand and actual conditions are not specified. A positive daily balance is not sufficient to design an installation.
Finding the answer is not evidence of mastery. Explain it, test a changed input and record your own work.
Your evidence checklist
Power uses W and energy uses Wh.
I show at least two changed assumptions.
I name a boundary beyond which my model cannot support a decision.
Independent challenge
The lamp is needed after sunset. Explain which additional storage evidence is missing before making a recommendation.
