2018 AQA GCSE Combined Science Specification
Topic - Cells
Notes - main activity is the kerboodle worksheet practicing calculating magnification. Can't upload for copyright reasons - but my suggestion would be to use a mixture of examples where pupils find one of the three variables in a mixed calculation worksheet, so pupils practice identifying when to rearrange.
Part of specification covered:
Students should be able to demonstrate an understanding of the scale and size of cells and be able to make order of magnitude calculations, including the use of standard form.
Students should be able to use estimations and explain when they should be used to judge the relative size or area of sub-cellular structures.
Students should be able to carry out calculations involving magnification, real size and image size using the formula:
Magnification = size of image / size of real object
Students should be able to express answers in standard form if appropriate.
MS 1b, 2a, 2h
WS 4.4
Use prefixes centi, milli, micro and nano.
MS 1d, 3a
AT 7
Images of cells in videos, bio-viewers, photographs and micrographs can be used as comparison for students’ own drawings.
AT 1 and 7
MS 1a, 1b, 2h, 3b
WS 4.4
Use prefixes centi, milli, micro and nano.
