||use scientific knowledge and understanding to turn ideas into a form that can be investigated and to plan an appropriate strategy;
||carry out preliminary work and make predictions, where appropriate.
||use observations, measurements or other data to draw conclusions;
||consider whether the evidence collected is sufficient to support any conclusions or interpretations made.
||suggest further investigations.
||how the sequence of, and evidence for, rock formation and deformation is obtained from the rock record.

AQA (GCSE Science A and B)
Biology 1b Evolution and Environment
Using skills & understanding of how science works to:
- interpret evidence relating to evolutionary theory.
- fossils provide evidence of how much (or how little) different organisms have changed since life developed on Earth.
Chemistry 1a Products from Rocks
- Limestone, and the environmental, social and economic effects of exploration.
- Products made from Geological resources.
Chemistry 1b Oils, Earth and Atmosphere
- the Earth consists of a core, mantle and crust.
- The earth’s crust and upper mantle (lithosphere) are cracked into tectonic plates caused by convection currents in the mantle to move at relative speed of a few centimetres per year.
Physics 1a, 1b.
Edexcel (GCSE Science)
B1a: Topic 1, Environment
- explain that fossils provide evidence for evolution.
C1b Topic 7, There’s One Earth
- discuss how the composition of the Earth’s atmosphere and its temperature have varied over different timescales.
OCR – GCSE (Gateway) Science)
B2: Understanding Our Environment
- State that fossils can provide evidence for living organisms from a long time ago.
- Explain that animals and plants can change over long periods of time and that fossils provide evidence for this.
- Describe how the relative positions of fossils in rock layers can be used to show evolutionary changes during long periods of time.
- Describe how organisms may have become fossilised: (hard body parts buried and gradually replaced by minerals; casts / impressions; preservation in amber, peat, tar, ice.
- Explain that the fossil record is incomplete: some body parts are rarely fossilised; fossilisation is rare; many fossils have not yet been discovered.
- Explain that when environments change some animal and plant species survive or evolve, but many become extinct.
C2: Rocks And Metals
- construction materials, including those manufactured from rocks in the earth’s crust.
- State that some rocks are used to construct buildings: granite, limestone, marble.
- describe that marble is much harder than limestone and that granite is harder than marble .
- Explain why granite, marble and limestone have different hardnesses.
- limestone is a sedimentary rock.
- marble is a metamorphic rock made by the action of high pressures and temperatures on limestone.
- granite is an igneous rock.
- State that limestone and marble are both forms of calcium carbonate.
- Environmental problems resulting form quarrying.
- State that the movement of tectonic plates results in volcanic activity and earthquakes.
- Describe the lithosphere as the (relatively) cold rigid outer part of the earth that includes the crust and outer part of the mantle.
- Explain that tectonic plates are found on top of the mantle because they are less dense.
- Describe the theory of plate tectonics.
- Describe how molten rock can find its way to the surface through weaknesses in the Earth’s crust.
- Explain that magma from the mantle must have a density less than that of the crust in order to rise through it.
- State that igneous rock is made when molten rock cools down.
- Describe magma as molten rock beneath the surface of the earth, and lava as molten rock that erupts from a volcano.
- State that some of the rock on the Earth’s surface has been formed by volcanic activity.
- Describe that some volcanoes give runny lava (iron-rich basalts) and some give thick lava and erupt violently (silica-rich rhyolites).
- Explain how the size of crystals in an igneous rock is related to the rate of cooling of molten rock.
- State that magma can have different compositions and that this affects the rock that forms and the type of eruption, limited to: basalt: runny and fairly “safe”, and explosive silica rich rhyolite (producing pumice, and volcanic ash, and bombs, sometimes with graded bedding).
OCR – GCSE (Gateway) Additional Science
P4: Radiation For Life
- Recall that radioactivity can be used to date rocks.
- Explain how the radioactive dating of rocks depends on the calculation of the uranium / lead ratio.
OCR – 21st Century Science
P1 The Earth In The Universe
- Recall that rocks provide evidence for changes in the earth (erosion and sedimentation, fossils, folding, radioactive dating, craters).
- Understand that continents would be worn down to sea level if mountains were not being continuously formed.
- Understand that the rock processes seen today can account for past changes.
- Recall that earthquakes, volcanoes, and mountain building generally occur at the edges of tectonic plates.
- Understand how the movement of tectonic plates causes earthquakes, volcanoes, mountain building and contributes to the rock cycle.
B3 Life On Earth
- Understand that evidence for evolution is provided by fossils.
P3 Radioactive Materials
- Understand the meaning of the term half life.
OCR – 21st Century Additional Science
C5: Chemicals Of The Natural Environment
- Recall that the Earth’s lithosphere is made up of a mixture of minerals.
- Recall that silicon, oxygen, and aluminium are very abundant elements in the crust.
- Recall that much of the silicon and oxygen is present in the Earth’s crust as the compound silicon dioxide.
- Recall the properties of silicon dioxide (e.g. hardness, melting point, conductivity and solubility in water).
- Explain the properties of silicon dioxide in terms of a giant structure of atoms held together by strong covalent bonding.
- Understand that silicon dioxide is found as quartz in granite and is the main constituent of sandstones.
Welsh Board – GCSE Science
