Secondary project briefs (ages 11+)


Bronze Awards are typically completed by students aged 11+. They complete a ten-hour project which is a perfect introduction to STEM project work. Over the course of the project, teams of students design their own investigation, record their findings, and reflect on their learnings. This process gives students a taste of what it is like to be a scientist or engineer in the real-world.


Silver Awards are typically completed by students aged 14+ over thirty hours. Project work at Silver level is designed to stretch your students and enrich their STEM studies. Students direct the project, determining the project’s aim and how they will achieve it. They carry out the project, record and analyse their results and reflect on the project and their learnings. All Silver projects are assessed by CREST assessors via our online platform.


Gold Awards are typically completed by students aged 16+ over seventy hours. Students’ projects are self-directed, longer term and immerse them in real research. At this level, we recommend students work with a mentor from their chosen STEM field of study. All Gold projects are assessed by CREST assessors via our online platform. There are more CREST approved resources that have been developed by our partners and providers specific to your region.

Which crisps are the healthiest? In this project, you will investigate the fat and salt content of different crisps. At the end you should suggest which crisps would be best for a patient with coronary heart disease. Before you start any tests, you should research the disease. Find out about the effects of high cholesterol and high blood pressure, and what in turn can cause these symptoms. Getting Started Choosing your crisps: You now have to choose some crisps to test - about six types should be enough. Try to get a wide variety. Find out, from the labels, how much salt and fat each one contains. Write down how much of each fat is saturated and unsaturated. Things to think about You may need some help from your teacher to find out how to do these tests. Three suggested techniques are: • Fat content – Gravimetric analysis • Salt content – Chloride titrations • Unsaturation – Bromine water titration Testing your crisps: You’re now going to carry out some tests to find (a) the fat content of the different crisps, (b) the salt content of the crisps, and (c) how unsaturated the fats are in the crisps. The results: Use the information gained from your results, together with your previous research, to decide which crisps would be best for somebody with heart disease. Explain why. How did your results compare to the values given on the crisps’ packaging? Can you explain why there were any discrepancies? Suggest some improvements to your methods. Useful Resources Ask people which crisps they buy, and ask for their reasons. You should find out what saturated and unsaturated fat means and find out just how low in fat something has to be before it can claim to be low-fat on its label. Click to edit project description
