1. Drawing distance time graphs
LO: to be able to draw a distance time graph and use the graph to calculate speed
Task: Discuss with partner and then make a list of what you must remember when drawing graphs

2. Use the graph to calculate the sprinters average speed
Distance-time graph for a sprinter
11.5b Distance-time graphs
Use the graph to calculate the sprinters average speed 2

3. Which graph shows the fasted speed
11.5b Distance-time graphs 3

4. Draw a distance time graph with this data
Time (s) 20 30 45 60 90
120
180
Distance (m) 8 12 16 22
100
1 Use your graph to find the distance travelled: ( answer in full sentences
After 100 seconds, the distance travelled was……..
After 10 seconds, the distance travelled was……..
After 57 seconds, the distance travelled was……..
After 145 seconds, the distance travelled was……..
2 Use the graph to calculate the speeds at each point above :

5. Drawing Graphs 1 Use your graph to find the distance travelled:
After 100 seconds
After 10 seconds
After 57 seconds
After 145 seconds
2 Use the graph to calculate the speeds at each point above :

6. 8 cm/minute 750 km/h 25 cm/year
Match the speed
Match the correct speed with the picture
37 km/h km/h km/h
8 cm/minute km/h cm/year

7. Use mini white boards to sketch distance time graph for this journey
11.5b Plenary
Use mini white boards to sketch distance time graph for this journey
Mikey the mole and his amazing journey
0 metres in 300 seconds
100 metres in 10 minutes
50 metres in 1200 seconds
300 metres in 6 minutes
0 metres in 60 seconds
500 metres in 7200 seconds
These data show the journey of Mikey the Mole: 7

8. Drawing Graphs Steps to drawing graphs correctly.
Make sure your data is accurate.
Decide which variable makes up the horizontal axis (it is the one you control, not the one you measure).
Find out the range for each axis – (usually 0 – largest value)
Split the range into a sensible number of sections that will fit in squares on the graph paper.
Select portrait or landscape for the graph paper based on (4)
Draw the axes in pencil, label and title in pen. (remember units)
Plot points and draw the curve.
