Low-resource or low equipment sharing resources


The resources on this page have been selected to support educators in finding CREST project ideas that require little equipment, can be run outside of a lab or at home, and use equipment that doesn’t require much sharing.

Find out more about the different CREST Award levels here: CREST Awards.

At primary level, our curated home learning packs don’t require many resources so they’re perfect to use either in the classroom or at home. For Primary teachers who have CLEAPSS access, we recommend this piece on doing Practical activities within your bubble.

At secondary level, each project brief has an overall challenge, ideas for getting started and a list of resources you might need. Read the health and safety section carefully before you begin. Young people should create a plan for their project and a risk assessment before they begin any practical activity. You can use the CLEAPSS student safety sheets as well as the rest of the CLEAPSS website to help them.

If you are looking for further advice on how to get started with CREST, visit our help centre and check out our FAQs.

If you are looking for ideas for running CREST at home, many of the below resources are suitable, and you can still access our Star and SuperStar Home Learning packs below. If you need further support, check out the CREST at home section of the Help Centre.

Page 1 of 2 Make your own fizzy drink Commercial fizzy drinks are fizzy because carbon dioxide has been pumped through them. In this project you will investigate how to make your own fizzy drink using carbon dioxide. You can compare your homemade fizzy drink to fizzy drinks you can buy in the shops. Getting Started Check out the recipes below as examples of how you might make your own fizzy drink. Make sure you do a risk assessment and check this with your teacher. Comparing your fizzy drink to a shop bought one: Buy a fizzy drink the same flavour as yours and compare: What different ingredients do the two drinks have? What do they look like? For example, is one cloudier than the other, or a different colour? How fizzy are they? How much carbon dioxide is given off when you open each bottle? How acidic are they? Measure the pH of the two drinks. What are the shelf-lives of the two drinks? What additives are there in the bought drink? Why do you think they have been put in? The results: How does your drink compare to the bought drink? How could you improve your drink? Can you think of ways to make your improvements? Click to edit project description Write down your method for making your drink so that other people can use it. Things to think about People have also been able to make fizzy drinks for hundreds of years by fermenting them. This is when yeast is used to make the carbon dioxide. Think about how a fermented drink might Find out about fermentation. What’s needed for it to happen and what’s produced? We do not recommend making a fermented fizzy drink yourself, unless supervised by a teacher in a lab.

Challenges for ages 5-11


These challenges take about an hour each. Once you have completed eight of them you can get a CREST SuperStar Award. Start by downloading the Passport. Children can use this to record each activity they complete.

Our curated packs for home learning require very little equipment or resources, so are ideal now that you are back in the classroom. They also add flexibility as students can finish their Star or SuperStar Award at home, if needed.

Each challenge has an organiser card and an activity card. All the instructions to set up the activity are in the organiser card. Read the 'watch out' section carefully before you begin. Children can use the activity card or you can read it through together.

Projects for ages 11-18


Each of these projects take between ten and thirty hours to complete. The project briefs have an overall challenge, ideas for getting started and a list of resources students might need. Before they begin, students should read the health and safety section carefully. Once students have completed their projects, they can get a CREST Discovery, Bronze, Silver or Gold Award. The amount of time spent on the project and how well they met the CREST criteria determines the level students will be awarded.

Start by downloading the relevant Workbook or Profile Form below. Young people can use these to help them complete their project and record their progress.

Young people should create a plan for their project and a risk assessment before they begin any practical activity, which should be checked by a teacher. You can use the CLEAPSS student safety sheets as well as the rest of the CLEAPSS website to help them.

For Bronze projects, once a student has completed their project, you can sign up to assess it and order their personalised certificate here. Bronze assessment is incredibly easy and can also be adapted for at-home learning if needed due to unexpected lockdowns, meaning parents can always assess when teachers cannot. Check out how to assess a Bronze project here

For Silver and Gold projects student work will need to be submitted online and will be assessed by a CREST assessor. Learn more about assessment for Silver Awards here
