KS3 Science · Year 7 · ages 11–12

Year 7 Science

Six half-term units, two each for biology, chemistry and physics, in the order we teach them: cells and organisation, particles and states of matter, forces, reproduction and growth, elements, compounds and mixtures, and energy stores and transfers. Below is the question each unit asks, what pupils produce, the representation it carries forward and the scientific skill it builds, taken from our Year 7 Science scheme of work.

The Year 7 resources

How the year is ordered

Six half-termly units, two per discipline. Each discipline starts where it actually starts: biology at the cell, chemistry at the particle model, physics at forces. Nothing else in key stage 3 works if these three are shaky.

Year 7 means ages 11–12, or S1 in Scotland.

The year, unit by unit

  1. Cells and Organisation

    Unit 1a · Biology · Autumn 1 · approx. 7 weeks · September – October

    If you are made of cells, why do you not look like one?

    Pupils produce
    An annotated microscope drawing from the student's own slide, with a written account of how the cell's structures relate to its job.
    Key representation
    The levels-of-organisation ladder: cell → tissue → organ → system → organism, used in every biology unit that follows.
    Working scientifically
    Measuring and recording. First use of a precision instrument, and the first time a drawing is a scientific record rather than a picture.
  2. Particles and States of Matter

    Unit 1b · Chemistry · Autumn 2 · approx. 7 weeks · November – December

    If nothing is added, why does a puddle disappear?

    Pupils produce
    A written explanation of three everyday changes of state in terms of particle arrangement, spacing and energy, with a cooling curve drawn from the class's own data.
    Key representation
    Particle diagrams — circles in three arrangements. Used in every chemistry unit for the next three years.
    Working scientifically
    Measuring and recording at intervals; plotting a line graph; using a model to explain rather than describe.
  3. Forces and their Effects

    Unit 2a · Physics · Spring 1 · approx. 7 weeks · January – February

    If nothing is pushing it, why does a rolling ball stop?

    Pupils produce
    An investigation report on one factor affecting friction, with a results table, a graph, and a conclusion that states what the evidence does not show.
    Key representation
    Force arrows: length shows size, direction shows direction, drawn from the object. Used in every physics unit that follows.
    Working scientifically
    The first full investigation of the key stage. Independent, dependent and control variables named before any data is collected.
  4. Reproduction and Growth

    Unit 2b · Biology · Spring 2 · approx. 7 weeks · March – April

    Why does a seed need a flower, and why do humans not?

    Pupils produce
    A comparison of human and flowering-plant reproduction, structured around the same four stages, with the adaptations of each explained rather than listed.
    Key representation
    The four-stage frame: make gametes → bring them together → fertilise → nourish the embryo. Applied to both organisms.
    Working scientifically
    Careful observation and recording during dissection; using a common framework to structure a comparison.
  5. Elements, Compounds and Mixtures

    Unit 3a · Chemistry · Summer 1 · approx. 7 weeks · April – May

    Salt is made of a metal that explodes in water and a poisonous gas. Why can you eat it?

    Pupils produce
    A separation of a supplied mixture into its components, with each technique chosen and justified from the properties of what is being separated.
    Key representation
    Particle diagrams extended: one kind of circle for an element, joined circles for a compound, unjoined mixed circles for a mixture.
    Working scientifically
    Choosing a technique from evidence about properties, rather than following an instruction. First time the method is a decision.
  6. Energy Stores and Transfers

    Unit 3b · Physics · Summer 2 · approx. 7 weeks · June – July

    If energy cannot be destroyed, why does your phone go flat?

    Pupils produce
    An energy transfer diagram for three everyday devices, each accounting for where the energy started, where it went, and why none of it was lost.
    Key representation
    Store-and-transfer diagrams: labelled boxes for stores, arrows for transfers, with the arrow widths meaning something.
    Working scientifically
    Accounting for a whole system; recognising that 'lost' energy has gone somewhere specific and saying where.

How it meets the key stage 3 programme of study

The scheme maps each requirement of the statutory programme of study for key stage 3 (Department for Education, 2013) to the unit that teaches it. Pupils should be taught to…

Working scientifically — scientific attitudes: pay attention to objectivity and concern for accuracy, precision, repeatability and reproducibility
Objectivity and accuracy established in 2a (variables and control) and 1b (measuring at intervals)
Working scientifically — experimental skills and investigations: ask questions, make predictions, select enquiry types and work safely
2a is the first full investigation · 3a chooses the method from properties · practicals in every unit
Working scientifically — analysis and evaluation: apply mathematical concepts, present data, identify patterns and assess error
1b cooling curves · 2a lines of best fit and anomalies · 3b efficiency as a proportion
Working scientifically — measurement: understand and use SI units and IUPAC chemical nomenclature
SI units from 1a onward, insisted on in 2a · chemical symbols and formulae in 3a
Biology: structure and function of living organisms · material cycles and energy · interactions and interdependencies · genetics and evolution
1a cells, specialisation and organisation · 2b reproduction in humans and flowering plants
Chemistry: the particulate nature of matter · atoms, elements and compounds · pure and impure substances · chemical reactions · energetics · the periodic table · materials · Earth and atmosphere
1b the particulate nature of matter · 3a atoms, elements, compounds, pure and impure substances
Physics: energy · motion and forces · waves · electricity and electromagnetism · matter · space physics
2a motion and forces · 3b energy stores, transfers and dissipation

This year deliberately does not cover chemical reactions, electricity, waves, photosynthesis, respiration or space. Each has a prerequisite that Year 7 is building: reactions need elements and compounds, electricity needs energy, photosynthesis needs both cells and reactions. All appear in Years 8 and 9, and the sequence is the reason they are not here. Earth and atmosphere is the one genuine gap in Year 7 and it is covered in Year 9 Unit 2b; if your department teaches it earlier, take it from Year 9 rather than adding it to an already full year.

Questions

  1. What does Year 7 Science cover?

    Six half-term units, in the order they are taught: Cells and Organisation, Particles and States of Matter, Forces and their Effects, Reproduction and Growth, Elements, Compounds and Mixtures and Energy Stores and Transfers.

  2. What do pupils produce in Year 7 Science?

    An annotated microscope drawing from the student's own slide, with a written account of how the cell's structures relate to its job; A written explanation of three everyday changes of state in terms of particle arrangement, spacing and energy, with a cooling curve drawn from the class's own data; An investigation report on one factor affecting friction, with a results table, a graph, and a conclusion that states what the evidence does not show; A comparison of human and flowering-plant reproduction, structured around the same four stages, with the adaptations of each explained rather than listed; A separation of a supplied mixture into its components, with each technique chosen and justified from the properties of what is being separated; An energy transfer diagram for three everyday devices, each accounting for where the energy started, where it went, and why none of it was lost.

  3. Does Year 7 Science meet the National Curriculum?

    Yes, across the three years of key stage 3. It maps each requirement of the statutory programme of study for key stage 3 (Department for Education, 2013) to the unit that teaches it, and on this year the scheme is plain: “This year deliberately does not cover chemical reactions, electricity, waves, photosynthesis, respiration or space.”
