Evaluation

Your teacher will probably be sharing and discussing these points with you:

  • Can you carry out a detailed survey using your observational skills and your previous knowledge?
  • Can you draw conclusions from your survey?
  • Can you present your evidence and explain your findings?

N.B. Feedback presentation could provide an opportunity for teacher assessment

The following is for your teacher:-

Expectations
most children will be able to:- . . . name and give characteristics of several rocks; explain that rocks are used for different purposes; recognise that there is rock under all surfaces and that soils come from rocks; recognise when a test or comparison is unfair; measure time and volume of water carefully; and say what their experiments and investigations show.
some children will not have made so much progress and will be able to:- . . . name one or two rocks; say that there are rocks under surfaces; and make measurements of time and volume.
some children will have progressed further and will also:- . . . explain how to make a test fair; explain precisely what was tested in their experiments and investigations into the uses of soils and rocks.

National Curriculum Levels

END OF UNIT ASSESSMENT - ROCKS AND SOILS

3 LEVELS OF EXPECTATION

AT1 SCIENTIFIC ENQUIRY

Pupils can;
Level 2

  • Recognise when a test or comparison is unfair
  • Make suggestions with support about how they might carry out an investigation
  • Make careful observations and descriptions
  • Compare findings with what they thought would happen, and try to explain it

Level 3

  • Put forward their own ideas of how to carry out a fair test
  • Measure accurately time and volume
  • Use observation and measurement to draw conclusions

Level 4

  • Plan and carry out a fair test
  • Explain their results from investigations in terms of the characteristics and uses of the soils and rocks tested
  • Take accurate measurements of time and volume
  • Use their scientific knowledge and understanding to explain, using scientific vocabulary, their conclusions

 

AT3 - KNOWLEDGE AND UNDERSTANDING

Pupils can;

Level 2

  • Name and describe one or two different kinds of rock, for example, marble and slate
  • Name and describe soil types, for example, sand and clay
  • Know that rocks occur naturally

Level 3

  • Name and describe the characteristics of several types of rock or soil
  • State that soil is made from rock
  • Recognise that there is rock under all surfaces

Level 4

  • Describe, using scientific vocabulary, the differences between rock samples
  • Explain how the soil's structure affects permeability
