Students learn when to use a line graph or a column graph, which variable goes on each axis, and how to choose a scale, label axes with units and give a graph a title. They describe trends, calculate a rate of change, interpolate and extrapolate from a cooling curve, and critique a poorly drawn graph.

Independent variable across the bottom, dependent variable up the side.
Read the passage, then answer the questions.
Use a line graph when both variables are numbers measured on a continuous scale, such as time, temperature or length. Use a column graph when the independent variable is made of separate categories, such as types of material or habitats.
Put the independent variable (the one you change) on the horizontal x-axis and the dependent variable (the one you measure) on the vertical y-axis. Label each axis with the variable and its units, choose a scale that goes up in equal steps and uses most of the grid, and give the graph a title.
Imagine the data plotted as a line graph. Show your working.
Investigation: A beaker of hot water was left to cool in a room at 22 °C. Its temperature was recorded every 2 minutes.
Time (min): 0, 2, 4, 6, 8, 10
Temperature (°C): 80, 64, 52, 43, 37, 33
Write True or False, then answer the extended question.
