Lesson details

Key learning points

  1. Displaying results in a table.
  2. Displaying categoric and numerical data.
  3. Interpreting and describing the results of an investigation into factors affecting seed germination.
  4. Identifying patterns or trends in the results.
  5. Writing a conclusion for an investigation into factors that affect seed germination.

Common misconception

Displaying results in a table landscape with variables the wrong way round.

Clear descriptions and examples of correct tables.

Keywords

  • Table - A way of displaying results to make them easier to read and interpret.

  • Categoric - Variables that have values that are labels.

  • Numerical - A value that is a number; these variables may display trends.

  • Conclusion - A description and explanation of findings.

  • Trend - A pattern displayed in data.

Put the pupils in groups matching the factor that they changed so that they can work together to produce and peer mark the correct tables and conclusions - if this was carried out as an open investigation.
