Matching graphs and scenarios
&copy; Nuffield Foundation 2012
Measuring pulse rate
Measurements
from real-life situations
give different shapes of
graph.
Using the cards, match each scenario with its graph.

At the end of the activity
When interpreting a graph, which key features are useful?
Describe a real situation that would give a linear graph.
Describe a real situation that would give a curved graph.
Describe a real situation that would give a graph with more
than one section (straight or curved).
