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.

Bridge Blunder

Bridge Blunder Organiser’s Card About the activity This activity is designed to get children thinking about weights, forces and measures. Children are set the challenge of helping Star Spans, a design company, fix their bridge and stop it swaying. Through this activity you will support your group to: • Build different models of bridges. • Test their different models to see which can hold the most weight and why. • Record and share their results. Kit list • A4 paper – 12 sheets per team (2 for initial exploration, 5 for their first trial, 5 for the final bridge). Have a few pieces in reserve. Scrap paper is fine. • Sellotape – you should restrict this to a short strip per group. Sellotape is only for securing things, not for wrapping round the paper. • 10 and 100 gram masses, coins, blocks or other equipment to act as ‘weights’ – bridges can support a surprisingly large mass. • Play blocks or similar to create the 20 cm gap for the bridge – or gap between chair and tables. • Pictures of bridges (optional) What to do 1. Introduce the activity using the story of Star Spans. You may want to show the children some pictures of different shaped bridges. 2. Give out activity cards and equipment to the children. 3. Explain that they will be using the equipment provided to test the best design for a bridge. Give the children a little time to talk together and to try making strong shapes using single sheets of paper. They can fold or cut the paper if they wish. 4. Encourage children to discuss their ideas and how to carry out their investigations. Prompt questions: • How many different kinds of bridge do you know? • Are some shapes stronger than others? • How will they make sure their test is fair? • How will they record their results?

5. Now give each group 5 sheets of paper and a small amount of tape. Tell them they have 10 minutes to try out ideas for how they might make their bridge. This will not be the final bridge. Let each group test their bridge with weights as they go along. You will need to decide together where to put the weights on the bridges to test them. 6. Encourage children to evaluate the design. What do they need to change to make the bridge stronger? Now they will make their final bridge. They will need more paper. Warn them that they are not allowed to use any of the old paper but can use their earlier ideas to help them. 7. Support children to conduct their tests and make their own records of their results. They could also take photographs or make drawings. After children have tested their bridges, provide time for them to talk through what was successful and what didn’t work. 8. Ask the children to present their bridge to the rest of the group and test it. Things to think about Make sure the weights are placed, not dropped, on the bridges. You can decide to spread weights evenly across the bridge (like the children in the story) or focus them in the centre. To make fair comparisons between the bridges the same test should be carried out on each one. Do not fasten the ends of the bridge to the supports. This does strengthen the bridge but if well fastened it can require large weights to make even a single piece of paper collapse. There are many solutions to this problem. The shape is all important. The weakest bridge is often a flat sheet of paper. It can be made stronger by flat folding, creating a triangular prism shape or rolling the paper along its length. Walls can add strength as can pillars or arches. Suspending the bridge can also help. We have used the term ‘weights’, rather than the more scientifically accurate ‘masses’, since this is the term that young children are more likely to know. Keywords • Construction • Weights • Masses • Suspension • Support 10 100 Take it further Children could act out a design award to showcase the bridge or bridges that were the strongest. Children could sketch their bridge and make notes about how it worked. Watch out! ! Avoid weights falling from a height. If bridges are high, you will need a bucket of sand or cardboard box filled with crumpled paper underneath to catch falling weights.

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
