Science Department

Eureka!

Our motto, “Eureka!”, is Greek for “I have found it!”. According to the Roman writer Vitruvius, Archimedes shouted it when he realized, in the bath, how to test a king's golden crown. Our head of science, Madame Curie, is named after Marie Curie (1867–1934), who won Nobel Prizes in both physics (1903) and chemistry (1911).

Works in the UK and the US. This version uses US school terms (kindergarten, Grade 3, high school); the UK version uses Reception, Year 4 and secondary school. · UK version of this page

Questions, experiments and explanations for curious minds of every age – from sinking and floating in kindergarten to university lab reports, in a classroom or at the kitchen sink.

This department is planned and ready to build – it needs funding

We have planned what the Science Department will teach and how it will work. Building it takes funding, so for now you can read our plan below and use the Classfern pages for science that are already live.

Practice tests you can use today

Madame Curie's lessons and experiments are planned but not yet funded. In the meantime, free science quizzes for 3rd grade through middle school are ready to try. They ask for no sign-up and score each answer with a clear explanation, with no personal details taken and no ads in sight. The finished science lessons will link back to these quizzes, and the quizzes to the lessons.

A shout from the bath

The story goes that Archimedes was so pleased with his idea that he ran through the streets without stopping to dress. Whether or not it happened quite like that, “Eureka!” captures the best moment in science: the second when an observation suddenly makes sense. The Science Department is planned around creating as many of those moments as possible.

Investigations with what is in the cupboard

Real science needs real things. We plan step-by-step investigations using ordinary materials – cups, salt, ice, magnets, seeds, a flashlight – each with a fair-test planner, a safety box and a results table that draws its own graph. What learners find is recorded as Evidence kept at home or in class, and it stays private to them.

On-screen experiments for the things you can't do

Some experiments are too slow, too dangerous or too big for a classroom. For those we plan interactive on-screen experiments: a circuit builder, a pendulum and ramp for forces, a particle model of melting and boiling, a food web you can disturb, and a germination timer that fast-forwards a week of growth. Each will finish with a few questions Marked by Classfern.

Science across the ages

For the youngest learners (preschool and kindergarten), science means noticing: sorting leaves, sinking and floating, watching ice melt. In elementary school it grows into planned tests and simple explanations of plants, animals, materials, light and sound. Middle and high school students will meet biology, chemistry and physics in depth, with practice on equations and practical skills, while university starters get help with lab reports and handling data. The science practice tests already on Classfern – Grades 3–8 for the US, plus Key Stages 2 and 3 and GCSE combined science for the UK – will slot straight in.

Madame Curie's lab rules

Marie Curie remains the only person to win Nobel Prizes in two different sciences, and much of her early research was done in a drafty shed. Our Madame Curie will be patient, precise and very keen on safety – fitting, since the radioactive materials she studied harmed her health. Expect her to remind learners to wash their hands, label everything and write results down straight away.

Curious? Visit Music

If you would like to see where Classfern is heading, visit our flagship Music Department. It already lets learners play along on a dozen instruments, test their ear and have a go at reading music, with clear feedback at every step. Science will aim for the same mix of curiosity and confidence.

Not yet built – but ready

Every part of this plan is waiting on funding. If you are a science teacher, technician or researcher with an experiment children adore, please tell us – it could become one of the first investigations we build.

Support the Classfern appeal

Every Classfern department is ready on paper, but each one needs funding before we can build it. A gift of any amount helps build Classfern – including new departments like this one – and keeps the free tools free for teachers, families and learners.
