Tables, charts, and graphs

Science · Scientific Inquiry · representational

Construct data tables with correct headings and SI units, plot appropriate graph types (bar chart, line graph, scatter graph), draw a line of best fit, and calculate the gradient of a straight-line graph

What mastery looks like

  • Constructs a table with column headings that include quantity and unit (e.g. Mass / g)
  • Selects the appropriate graph type for the data and plots it accurately with labelled axes and scales
  • Draws a line of best fit for linear data and correctly calculates its gradient using two points

Check your understanding

If Tables, charts, and graphs collected data on how spring length changes with the weight added, could they put it in a correct table, plot it as a line graph with axes labelled in the right units, draw a line of best fit, and calculate the gradient?
