How this programme works

The whole of KS3 chemistry in eight weeks: particles, mixtures, atoms and the Periodic Table, then reactions, acids, metals, materials and the Earth.

  • 8 weeks, one theme each

    Every week has a clear focus so you always know what you are working on.

  • 20 lessons

    Two or three short lessons a week, each one marking itself as you go.

  • 8 weekly assignments

    A mixed set written for that week, so you find out what stuck before you move on.

  • Two days a week to review

    Each week ends with a review day and a rest day, so your streak is safe.

  • A mentor on hand

    Premium members can message their mentor from the top of this page at any time.

  • A video drop-in every Saturday

    At 12:00 UK time, premium members join a live call and ask anything, face to face.

  • A final review

    One longer test across every week at the end. Pass it, or aim for a distinction, and see exactly which weeks to revisit.

  • A cohort with you

    Everyone who enrols starts on the same Monday and shares a leaderboard.

What you will cover

KS3 Chemistry 1: Particles, states and separating mixtures · KS3 Chemistry 2: Atoms, elements and the Periodic Table · KS3 Chemistry 3: Chemical reactions and energetics · KS3 Chemistry 4: Materials, the Earth and the atmosphere

Example lesson: KS3 Chemistry 1: Particles, states and separating mixtures

This is the very first lesson of week 1, open to everyone with an account. It shows how a lesson moves from a short explanation to activities that mark themselves.
