Matching graphs and scenarios Nuffield Free-Standing Mathematics Activity Matching graphs and scenarios

Measurements from real-life situations give different shapes of graph. Measuring pulse rate Using the cards, match each scenario with its graph.

Conversion graph (miles against kilometres) 160 100 miles kilometres

Graph showing 100 mile journey 2 100 Distance travelled (miles) Time (hours)

Graph showing amount of oil in tank (litres) 5 100 Time (days)

Graph showing temperature of water (C) 20 100 60 Time (minutes)

Graph showing temperature of bread (C) – 20 30 Time (minutes)

Conversion graph (F against C) 100 212 32 Temperature (F) Temperature (C)

Graph showing vehicle travelling at a steady speed before an emergency stop 50 Speed (mph) Time (seconds)

Graph showing depth of water in bath 5 50 Depth (cm) Time (minutes)

Graph showing vehicle setting off from junction 10 50 Speed (mph) Time (seconds)

Graph showing growth of a plant 10 50 Height (cm) Time (weeks)

Graph showing heart rate in exercise 100 50 Heart rate (beats/minute) Time (minutes)

Graph showing amount of water in container 200 50 Amount (ml) Time (seconds)

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).
