At the end of this unit
in terms of scientific enquiry
most pupils will: make effective use of secondary sources of information about the relationship of soil type to plant growth and record their findings using ICT; identify and describe possible sources of information about the environment and select from these evidence about environmental change over time, identifying some strengths and weaknesses in the evidence
some pupils will not have made so much progress and will: select information from secondary sources relating plants to soil type and record findings using ICT; describe how some sources provide evidence about environmental change
some pupils will have progressed further and will:
identify and explain the strengths and weaknesses of the evidence about environmental change obtained from secondary sources
in terms of materials and their properties
most pupils will: describe in terms of chemical reactions how acid rain arises and how it affects rocks, building materials and living things; describe how air and water pollution are monitored and how they might be controlled; distinguish between different environmental problems
some pupils will not have made so much progress and will: describe some of the consequences of acid rain and of other forms of pollution; identify why it is important to monitor and control pollution
some pupils will have progressed further and will:
describe a variety of environmental issues and explain the implications of these
