Ways of working
Students are able to
• draw conclusions that are supported by evidence, reproducible data and
established scientific concepts.
• reflect on learning to identify new understandings and future applications.
Knowledge and Understanding
• Scientific ideas can be used to explain the development and workings of
everyday items.
Life and living
Living things have features that determine their interactions with the
environment.
• Living things can be grouped according to their observable characteristics
e.g. flies are insects
• Reproductive processes and life cycles vary in different types of living things
e.g. flies develop through stages
• Living things have relationships with other living things and their environment
e.g. the relationship between a fly and its surroundings is mutually beneficial
