Primary challenges (ages 5-11)


Typically completed by 5-11 year olds (Key Stages 1 and 2), CREST Star and SuperStar challenges relate to everyday experiences.

The activities are designed to be easy-to-run and low-cost, and you don’t need to be a teacher, have a science background or have access to specialist equipment to run them. Children are eligible for a CREST Award after completing eight of the challenges and you’ll find helpful hints and tips in each pack for you to use, explaining the scientific themes and offering guidance on conversation topics for your children.

There are many more CREST resources which have been developed by our partners and by providers in your region. Click here for links to CREST accredited resources developed by partner organisations, CREST accredited schemes and education providers who can deliver CREST accredited activities.

Buy Them Try Them

Buy Them Try Them Organiser’s Card About the activity This activity is designed to get children thinking about toothpaste, what it is made from and how different brands of toothpaste differ. The children have been shown an advert for Bright Smile Toothpaste. Can they do some tests to check that the claims are correct before the ad goes to print? They’ll have to check people agree with the advert first! Through this activity you will support your group to: • Carry out investigations on manufactured toothpaste • Compare these with a homemade toothpaste (optional) • Carry out toothpaste surveys. Kit list • At least 3 different brands of toothpaste for comparison • Spare clean toothbrushes (not for teeth cleaning) • White tiles or old plates • Permanent markers or shoe polish • Additional plastic containers and/or plates • Covering for the tables • Plastic aprons What to do 1. Introduce the activity using the story. 2. Give out activity cards and equipment to the children. 3. Explain that they will be exploring different kinds of toothpaste and doing a survey on their friends and family to find out which toothpaste people like best and why. 4. Encourage children to discuss their ideas and how to carry out their investigations. 5. Support children to conduct their investigation and make their own records of their results. If children do have their own toothbrushes, they could test the toothpastes with dental disclosing tablets on their own teeth. Using plates and markers may make a better investigation. 6. Ask the children to present their findings to the rest of the group, they can be as creative in their presentation as they want.

Keywords • Toothpaste • Cleaning • Survey Watch out! If children use the toothpaste on their own teeth, they will each need their own brush and toothpaste sample. Homemade toothpaste should only be tasted if you are certain it has been prepared hygienically. British Science Association Registered Charity No. 212479 and SC039236
