What is Cartana?
A revision game for KS3 science. Each island on the chart is one topic. You sail there, play through it in short runs of questions, read the notes when you’re stuck, and beat the villain who has taken the island over.
Who is it for?
Children in Years 7, 8 and 9 (ages 11 to 14). It follows the KS3 national curriculum for England, so it fits alongside whatever your child is doing at school.
What’s in the beta test?
All seven biology islands (cells, digestion, body systems, reproduction, photosynthesis, ecosystems and genetics), an island on working scientifically, and the first physics island: electricity and magnetism. Chemistry and the rest of physics are being built.
Is it really free?
Yes. The beta test is free: no card details, no adverts and nothing to buy.
What do testers have to do?
Play as much or as little as you like between 1 and 31 December, then tell us what you thought. Your feedback decides what we fix and build before the full release in 2027.
What do we need to play?
A phone, tablet or computer with an up-to-date web browser. There is nothing to download or install.
How does my child sign in?
You register with your email address, and before the beta opens we email you how to join. We then make a login for each child from a first name or nickname. Children never give us an email address or anything else.
Is it safe?
There are no adverts, no chat, no friends lists and no leaderboards, and nothing about a child is visible to anyone else. You can delete everything we hold at any time. The details are in our privacy notice, which has a short version for children.
Do you do maths too?
Yes: Cartana also has free KS3 maths worksheets, topic test papers and video lessons. See the maths pages.
