Chemistry 11 & 12 · Physics 11 & 12
Science,
sculpted in glass.
Eight ideas from the course, built in 3D and sealed in glass. Scroll to walk past them; drag sideways to turn each one.
Chemistry 11 · Bonding
A crystal of
table salt.
Sodium and chloride ions lock into a perfect cube. Every ion is held by six neighbours of the opposite charge.
Bonding & nomenclatureChemistry 11 · The mole
Twelve grams
of carbon.
The diamond lattice: each carbon bonded to four others. Twelve grams holds 6.02 × 10²³ of them, one mole.
The mole & stoichiometryChemistry 12 · Equilibrium
Busy, but
balanced.
Particles keep crossing both ways. At equilibrium the two rates match, so the amounts stop changing.
Le Chatelier's principleChemistry 12 · Redox
Electrons
on the move.
Zinc gives up electrons, copper takes them. Run them through a wire and you've built a battery.
Electrochemical cellsPhysics 11 · Forces
Every push,
drawn in.
Applied force, friction, normal force and gravity on one cart. Add them up and Newton tells you what happens next.
Forces & Newton's lawsPhysics 12 · Circular motion
Always pulled
to the centre.
A ball on a string never stops turning. The pull points inward; the velocity always points along the circle.
Circular motionPhysics 12 · Circuits
Close the loop,
light the bulb.
Charge flows the moment the circuit is complete. V = IR tells you how much.
CircuitsPhysics 12 · Induction
Move a magnet,
make a current.
Push the magnet into the coil and the meter kicks. Pull it out and it kicks the other way.
