What's inside
🧊 Matter & Atoms
Everything around you is made of matter: this page, the air you breathe, even you. Let's zoom into atoms and see how matter changes state.
🎢 Forces & Motion
Pushes and pulls make the whole world move! Let's explore the forces that start, stop and steer everything around you.
âš¡ Energy
Energy makes everything happen, from a bouncing ball to a glowing lightbulb. It never disappears; it just changes from one form to another.
🧲 Electricity & Magnetism
Flip a switch and a room fills with light. Wave a magnet near a paperclip and snap, it jumps! Electricity and magnetism are secretly best friends.
Key ideas
- Matter is anything that takes up space and has mass: solid, liquid, gas and plasma are its four states.
- Newton's three laws explain how forces change motion, from inertia to action-and-reaction pairs.
- Energy comes in many forms (kinetic, potential, heat, light, sound, electrical) and is never created or destroyed, only changed from one form to another.
- Electric current needs a complete circuit to flow, and materials are either conductors or insulators.
- Magnets have north and south poles: like poles repel, opposite poles attract, and a coiled current can even make a temporary electromagnet.
