Primary challenges (ages 5-11)

Typically completed by 5-11 year olds, CREST Star and SuperStar challenges relate to everyday experiences. Children complete eight activities to gain a CREST Award, with each activity taking between 45 minutes and one hour to complete.

The activities are designed to be easy-to-run and low-cost. You don’t need to be a teacher, have a science background or have access to specialist equipment to run them. The packs contain helpful hints and tips for you to use, explaining the scientific themes and offering guidance on conversation topics for your children.

There are more CREST approved resources that have been developed by our partners and providers specific to your region.

Tunnel Tourists Fact

Tunnel Tourists Fact Sheet At 37.9km (23.5miles), the Channel Tunnel is the longest under-sea tunnel in the world. Eurotunnel Le Shuttle has carried more than 26 million trucks since it opened in 1994. Dinosaurs were wandering the Earth when the chalk layer that the Tunnel cuts through was deposited during the Cretacious period, 66 million years ago. 380,000,000 tonnes of freight have been transported via the Tunnel since it opened. Over 2 million dogs and cats have travelled with Eurotunnel since it opened, representing 80% of all pets crossing the Channel. 11 boring machines were used to make the Tunnel. In total they weighed 12,000 tonnes. 185 million passengers have travelled through the Tunnel since 1994. 4.9 million cubic metres of Chalk Marl were excavated during construction and used to create Samphire Hoe in Kent and a hill at Le Fond Pignon in France. 13,000 engineers, technicians and workers helped construct the Tunnel. 80 million vehicles have boarded the Shuttle since it opened. 26 million roses are delivered through the Tunnel each day. 1 million express delivery parcels travel through the Tunnel each day

Under Your Feet Organiser’s Card FEET UNDER YOUR FEET About the activity This activity is designed to get children thinking creatively about nature. Stella Storyteller is struggling for inspiration for her latest story book. It’s the story of two special children who wake up one morning and find themselves the size of ants. Can the children help to find a challenge for the intrepid duo? Through this activity you will support your group to: • Think about the world around them from a different perspective • Investigate and explore what living things they can find outdoors • Record their thoughts and ideas and present them to share with the group Kit list • Cut out ‘feet’ for children to record their results on - you might want to provide a template as children’s feet are usually too small • Cut out ‘holes’ for children to place on the ground and look through • Hand held magnifiers • Identification charts or books • Drawing materials – thin coloured markers or pencils etc. • Digital camera (optional)
