Year 9 Science
The cell in detail and the tissues it makes, naming and ordering the diversity of life, how living things reproduce — and the atom pulled apart into protons, neutrons and electrons, sound as a wave, and energy that is never lost, only spent.

- The cell and what is inside itLesson
Name the parts of a plant and an animal cell and say what each does, tell a prokaryotic cell from a eukaryotic one, and use osmosis to explain what happens to a cell in salty water.
- Plant and animal tissuesLesson
Name the three meristems and the permanent tissues they become, match each plant and animal tissue to its job, and tell the joints and muscle types apart by what they do.
- Diversity and classificationLesson
Place an organism in one of the five kingdoms, run the hierarchy from kingdom down to species, and read and write a scientific name in the binomial system.
- Reproduction: how life continuesLesson
Tell asexual reproduction from sexual, name the parts of a flower and follow pollen through to a seed, and describe fertilisation and the reproductive cycle in animals and humans.
Chemical sciences
- Inside the atomLesson
Count protons, neutrons and electrons from an atomic number and a mass number, fill the shells and read off a valency, and say what makes two atoms isotopes.
- How atoms combine, and what a molecule weighsLesson
Use the laws of conservation of mass and of constant proportions, tell a covalent bond from an ionic one, write a formula by crossing over valencies, and add up a molecular or formula unit mass.
- Mixtures, concentration and separationLesson
Tell solutions, suspensions and colloids apart, work out a concentration as a percentage, and choose the right method for pulling a given mixture apart.
Physical sciences
- Sound wavesLesson
Say why sound needs a medium, use v = λν and ν = 1/T, work out an echo distance, and place a frequency in the infrasonic, audible or ultrasonic band.
- Work, energy and powerLesson
Work out work done, kinetic energy, potential energy and power, say when work is positive, negative or zero, and explain what a pulley, a ramp and a lever actually change.
