Learning objects Filling glasses: find the right glass

TLF ID L1105

Look closely at some line graphs. Examine the relationship between the shape of a glass and the time taken to fill it with juice. Notice that the fluid level rises more quickly in a narrow glass than in a wide glass. Choose the glass shape that matches a line graph representing its filling rate. This learning object is one in a series of five objects.

Educational details

Key learning objectives
  • Students create and interpret graphs that represent the relationship between quantities and show the rates of change.
  • Students match different shaped vessels with the line graphs representing their filling rates.
Educational value
  • Illustrates how the shape and slope of a graph can be linked to physical attributes of objects.
  • Students associate the shape and slope of a graph of filling rate with the shape of a glass.
  • Feedback is delivered visually.
