Year 9 is the awkward bridge year: still Key Stage 3 in school life, but already starting GCSE habits. This page gives free Year 9 Science practice from GradeNinja's own bank - 79 auto-marked questions across 1 Year 9 topic set.
The aim is not to cram GCSE papers early. It is to make the first GCSE topics feel normal: short retrieval practice, clear corrections, and enough repetition that classwork sticks before Year 10 gets busy.
Use these as ten-minute checks after a lesson or before homework. If you miss one, read the explanation, then come back tomorrow and answer it cold.
Year 9 questions are pulled from late Key Stage 3 and foundation GCSE bridge material. They should feel harder than Year 8, but they are not meant to be full Year 11 exam questions.
Answer first, then reveal. The useful bit is the retrieval attempt, not reading the answer. If a topic keeps going wrong, paste the homework or Google Classroom text into GradeNinja's Classroom import tool and turn it into a focused pack.

Carbon
Carbon has atomic number 6, meaning it has 6 protons in its nucleus. It is the basis of all organic chemistry.
Gain of oxygen (or loss of electrons)
Oxidation is defined as the gain of oxygen or the loss of electrons in a chemical reaction. This process often involves the increase in oxidation state of an element. Key to remember is that oxidation is associated with electron loss.
Kinetic, thermal, chemical, gravitational potential, elastic potential, nuclear, electromagnetic
The main stores of energy include kinetic, thermal, chemical, gravitational potential, elastic potential, nuclear, and electromagnetic energy. Each type of energy has unique characteristics and applications in various physical processes. Remember, energy can exist in different forms, each with its own significance.
Anther
The anther is the part of the stamen that produces pollen grains, which are the male gametes.
Glucose + oxygen → carbon dioxide + water (+ energy)
Aerobic respiration uses oxygen to fully break down glucose, releasing carbon dioxide, water, and a large amount of energy.
Igneous
Igneous rock forms when magma (underground) or lava (at the surface) cools and solidifies. The word igneous comes from the Latin for fire.
Skeletal system
The skeletal system provides support, enables movement, and protects organs such as the brain (skull), heart and lungs (ribcage).
Ampere
Electrical current is measured in amperes (amps, A), using an ammeter connected in series in the circuit.
Iron dissolves and copper is deposited
Iron is more reactive than copper, so it displaces copper from the solution. Iron dissolves and a coating of copper metal forms on the iron.
Four
The heart has four chambers: the right atrium, right ventricle, left atrium, and left ventricle.
Lactic acid
When muscles work very hard without enough oxygen, anaerobic respiration produces lactic acid, causing the burning sensation in tired muscles.
Cell membrane
The cell membrane is a partially permeable barrier that controls the movement of substances into and out of the cell.
A list of metals ordered from most reactive to least reactive
The reactivity series ranks metals from most reactive (e.g. potassium) to least reactive (e.g. gold). It helps predict how vigorously a metal reacts and whether displacement reactions will occur.
Potassium
Potassium is one of the most reactive metals, reacting violently with cold water. Gold sits near the bottom of the reactivity series.
Proton
Protons carry a positive charge. Neutrons have no charge, and electrons are negatively charged.
Crust → mantle → core
The Earth's layers from outside to centre are: crust (thin outer layer), mantle (thick semi-molten rock), outer core (liquid iron/nickel), and inner core (solid iron/nickel).

Start revising free →They are bridge questions: harder than early Key Stage 3, but not pitched as full Year 11 GCSE exam papers. The point is to prepare the habits and core knowledge early.
Yes. Use Classroom import in the app: paste the Google Classroom post, homework email or assignment brief and it turns the topics into practice questions and flashcards.
Short and often. Ten minutes after a lesson or a few times a week is more useful than one long session before a test.
Yes, signing up is free. GradeNinja has Year 9 bridge content plus the wider question bank across 28 subjects.
