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.

Page 1 of 2 Compare suncreams In this project, you will measure the UV radiation to find out when the sun’s UV rays are the strongest. You will then compare a variety of different sun creams and sun blocks by measuring how much UV radiation they stop. Getting Started Conduct some research into the dangers of over-exposure to the sun. Try to find ways of measuring UV radiation - find out if it’s possible to measure UVA and UVB. Measuring UV radiation: Once you’ve decided on a method for measuring UV radiation carry out experiments to see when the sun’s UV rays are strongest. Try to conduct the experiments throughout a year, so you can compare the differences between the four seasons. Find out what the sun index is, and how it’s affected by the time of year, time of day and the amount of cloud cover. During your testing, check the sun index on weather reports to see if your results correspond with those of the professionals. Testing sun creams: You should choose a variety of different sun creams and sun blocks to test and determine how much UV radiation they stop. Use a UV spectrophotometer to measure which parts of the electromagnetic spectrum are absorbed by different sun creams and sun blocks (you will need to visit a university to use a spectrophotometer). Think about how to communicate your findings. Click to edit project description Things to think about Think about which tests are more accurate and consider why this is. Useful Resources Contact a university to see if it has a UV detector you could use. It would be good if you could link up with a chemist working for a sun cream manufacturer or an analytical chemist in a university. They should know how sun creams are tested in industry.
