Interpreting Graphs I can interpret information from graphs

Interpreting Graphs - I can interpret information from graphs - I know to check the axes to determine the quantities being measured and the scale

Interpreting the shapes of graphs Smudger eats a bar of chocolate. This graph shows how the mass of the chocolate bar changes as it is eaten. Mass of chocolate (g) 150 Eating a bar of chocolate 100 50 0 0 10 20 30 40 50 60 70 80 90 100 Time (seconds)

Interpreting the shapes of graphs Temperature of water This graphs shows how the temperature of the water in a pan changes when frozen peas are added. Time

Which graph is correct? In an experiment a group of pupils poured water onto a sponge and weighed it at regular intervals. Each time the sponge soaked up all the water. Volume of water (cm 3) Graph C Mass of sponge (g) Graph B Mass of sponge (g) Graph A Mass of sponge (g) Which graph is most likely to show their results? Volume of water (cm 3) Graph D Volume of water (cm 3)

Sketching graphs A group of pupils are conducting an experiment. They fill three beakers with boiling water and record the temperature of the water over time. The temperature graph for beaker A looks as follows: How would the graphs for beakers B and C compare to this? Temperature (o. C) Beaker A has no wrapping, Beaker B is wrapped in ice and Beaker C is wrapped in insulation fibre. Beaker A Time (minutes)

Distance-time graphs In a distance-time graph the horizontal axis shows time and the vertical axis shows distance. For example, this distance-time graph shows a journey. distance What does the slope of the line tell us? The slope of the line tells us the average speed. The steeper the line is, the faster the speed. 0 time

Information Graphs • On information graphs, always look to see 1. What information each axis gives (label) and 2. What one square represents (scale) • When describing a graph you need to state: 1. The distance moved (travelled) 2. The time taken to move 3. The speed (rise/run) 4. The direction of travel (away from or towards) FOR EACH SECTION OF THE GRAPH!
