Iron Man Dessert
Make an iron-rich athlete snack or dessert to sell sale in cafes and gyms.
Technology 2.4 - Undertake effective development to make and trial a prototype.
Exemplars showing how others have tackled it.
This student has made a refined prototype for a mobile chilly bin.
This student has evaluated practical techniques and processes to determine their appropriateness for use (1), and used evidence from ongoing testing and stakeholder feedback to inform the making and trialling of the prototype (2).
To reach Excellence, the student could synthesise the on-going testing and stakeholder feedback. Often decisions seemed to be made on the basis of ‘what my stakeholder and I decided’, and the justification for this decision making could be more apparent.
If you want to change the brief, negotiate with your teacher.

EVALUATE & CHOOSE
Evaluate possible ingredients and processes for the iron-rich athlete snack.
Choose the best ingredients and processes for your iron-rich athlete snack.
Use recipes and research to EVALUATE possible ingredients and processes for your iron-rich athlete snack. CHOOSE the best ones to try out.
In your portfolio: Keep a record of recipes and different ingredients you have evaluated. Indicate which ingredients you have chosen to try out and why, and which ones you have rejected, and why.
Some points to consider about different ingredients:
- Are they locally grown?
- Are they gluten free, dairy free, refined sugar free?
- Are they iron-rich, wholegrain and supporting health?
- How do they look and taste? Do they give results your stakeholders would like?
- How easily are they cooked/prepared into your iron-rich athlete snack? Do I have the necessary tools/equipment to work with these ingredients?
In your portfolio: Keep a record of cooking methods and other processes you have evaluated in your portfolio. Indicate which processes you have chosen to try out and why, and which ones you have rejected, and why.
Some points to consider about different processes::
- Do I have the tools/equipment needed for this process?
- Can I do it the same every time so my outcome is consistent?
- Does it preserve the quality/health benefits of the food?
- How practical is it, how long does it take? Will it make the outcome too expensive?
TRIALS & TESTS
Compare different ingredients. Compare different processes.
Try it out, see how it goes.
Using the ingredients and processes you evaluated and chose, conduct tests and trials to see how they perform.
For example, you may try out 3 different sweeteners in a dessert (keeping everything else the same), and get customers to blind-taste each one. Use the feedback to inform your decision making.
What ingredient tests will you do? Write down your results in your portfolio.
For example, you may try making a component by hand or using a food processor, blender or Thermomix to automate the process. Compare the results. Make an informed decision on the best processes to use.

Tests and Trials
Student tests different ingredients in the pastry in small batches - each tray marked 1-6. Different processes are used - some baked with "baking beans" (above), others without. Also different cooking times and temperatures trialled.
Once the best pastry is chosen (customers try them), student manufactures a large pie with the best pastry from the trials.
Combine stakeholder feedback and your results from ongoing tests and trials to make the best possible iron-rich athlete snack.
Feedback, feedback, feedback.
Get feedback from your key stakeholder all the way. Write it down.
Get feedback from experts, end-users and all kinds of stakeholders.
Consider stakeholder feedback in all your decisions.
TRIAL YOUR SNACK/DESSERT IN CONTEXT
Social environment - people who will be interacting with the outcome. Physical environment - where the outcome will be situated.
Trialling your product in context
Trial your iron-rich athlete snack in its intended social environment (the people who will be interacting with the outcome), and physical environment (where the outcome will be situated).
Record these trials, and the results of them in your portfolio. What did you learn? How did this inform your prototyping and product development? What decisions did you make as a result? 📗
ACCEPT OR MODIFY?
Justify your decisions to accept or modify your prototype.
Is your prototype fit for purpose, or does it need to be modified?
State whether you accept your prototype, and the manufacturing process you have developed for it, or whether it needs to be modified.
Give your reasons. Include reasons from:
- Stakeholder feedback
- Results from your tests and trials
- Results from trialing your prototype in context
You can use this template if you like. Paste your decisions into your portolio.📗
Justify your your prototype meets your specifications.
Make sure your portfolio includes your prototyping journey.
Keep a journal of your progress.
Photos with descriptions of what you did and why are a great way to tell your story.
Make sure your portfolio includes all the following:
- The brief that you used. (State who your key stakeholder is.)
- The final recipe and planned manufacturing process.
- Evidence of all your:
- evaluations (of different ingredients and processes you could use)
- tests (of different ingredients and processes)
- trials (of your prototype in its intended social and physical context)
- decisions (always include stakeholder feedback)
- Justification that your athlete snack/dessert is fit for purpose or that it should be modified.
- A final list of specifications, justifying that each one has been met.
