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.

Tea Bag Trouble

Tea Bag Trouble Organiser’s Card BLE About the activity This activity is designed to get children thinking about materials. Uncle Astro wants to make a nice cup of tea but he’s run out of tea bags. The shop is only selling packets of loose tea leaves. Uncle Astro doesn’t like tea leaves floating around in his drink, so Cosmic and Gem wonder if they can make him some tea bags. Through this activity you will support your group to: • Think about what makes a good tea bag • Test different materials and observe how they behave when used as a tea bag • Record TEABAG their TROUBLE results and share them . Kit list TEABAG TROUBLE • Loose tea leaves and tea bags • Water from the hot tap (see Safety). • Clothes pegs • Selection of different materials e.g. tissues, newspaper, kitchen roll, silk, cotton, tissue paper, crepe paper • Teaspoons, clear containers, measuring jug, minute timer. • Scissors and thermometers • Coloured pencils, including brown What to do 1. Give out the activity cards and introduce the activity by reading the story together. 2. Get the children to talk about the questions and the opinions of Aunt Stella, Gem and Cosmic. 3. Look at some tea bags together. Talk about making tea. 4.If possible let them choose their own materials. 5. Check that they understand how to make tea bags using the pegs. Let them talk about what makes a good tea bag (lets colour and flavour out and keeps tea in). 6. Discuss safety issues when using hot water. 7. Ask the children to draw cups of tea to show what happened. Encourage the children to use lighter or darker browns to show the tea colour and to draw in tea leaves.

UBLE Things to think about They need to fix the peg so that the tea leaves cannot escape through the top. Children may need to practice. Thin or soft materials are easier to use. Some materials will absorb a lot of water and some will tear easily. Encourage children to notice this. Children should be encouraged to use the same amount of tea in each bag, the same sized piece of material, the same volume and temperature of water, and to dunk for the same amount of time. Encourage children to observe differences in tea colour and the number of escaping tea leaves. To show off their research, children can draw pictures of cups of tea. They can stick a piece of the appropriate tea bag material next to each picture. Take it further The first tea bags were made from silk muslin in 1903 in the USA. Tea bags weren’t popular in the UK until the 1950’s. Now 96% of all tea sold in the UK is contained in tea bags. Modern tea bags are usually made of paper fibre and heat sealed. They come in square, rectangular, circular and pyramidal shapes. The quality of the tea in the bags varies. Some can have a high quantity of tea dust in them. Bags with whole leaves tend to take longer to brew. Keywords TEABAG TROUBLE • Hot Water • Tea • Absorption • Filtration • Materials Watch out! Water from the hot tap will work. Check its temperature before use to make sure it is not too hot for children to use. Try to prevent over vigorous dunking and splashing. Children should not drink the tea.

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
