Revision Checklist (I can...)
 describe photosynthesis.
 name the reactants of photosynthesis and I know where they come
from.
 name the products of photosynthesis.
 identify the special features of leaves that help them photosynthesise.
 write a word and/or symbol equation for photosynthesis.
 identify variables that may be important when investigating
photosynthesis
 describe how roots take in water and nutrients from the soil.
 identify the special features of roots that help them take in water and
nutrients from the soil.
 identify the ways in which plants use water
 describe the ways in which plants use glucose
 describe how new materials (biomass) can be made from glucose.
 describe how photosynthesis and respiration affect the oxygen and
 carbon dioxide levels in the air.
 describe how cutting down the rainforests can affect climate and living
things
 relate my ideas about photosynthesis and respiration to wider
environmental issues
 describe and explain how sediment becomes sedimentary rock
 describe the main features of sedimentary rocks, metamorphic rocks
and igneous rocks
 know that high temperatures and pressures can change one type of rock
into a metamorphic rock.
 describe the conditions needed for metamorphic rock to be formed.
 describe how igneous rocks form when magma cools
 explain how the size of crystals in igneous rocks depends on how fast
they cool down
Please remember that knowledge and skills acquired in other topics and in previous
years may still form part of the test you will take. Lifelong Learning is key.

 explain what happens to the particles in magma as it cools to form small
and large crystals in igneous rock

from the Earth.
