describe what aerobic respiration is and what is needed.
describe aerobic respiration using an equation.
describe anaerobic respiration using an equation.
describe how respiration takes place in every living cell of
humans, plants and other living things.
describe how oxygen gets into the body and carbon
dioxide gets out
describe how oxygen and carbon dioxide are exchanged
between the blood and the alveoli in gas exchange.
name the differences between inhaled and exhaled air.
describe how the shape and large number of alveoli helps
them to do their job in the lungs.
describe how damaged alveoli result in less gas
exchange.
describe how the heart and blood vessels keep up a good
blood supply to the tissues.
describe to someone else the difference between a
compound and a mixture using my ideas about atoms.
explain to someone the difference between atoms and
molecules.
identify at least three ways to recognise a chemical
reaction is taking place.
use my ideas of atoms to describe what happens when
chemicals react to form new substances.
describe how a scientist uses the word pure.
