Humans grow continuously and at changing rates from birth until the end of puberty.
Mean averages can be used to help us analyse large data sets.
Human height can be measured and plotted on a line graph to show how height varies with age.

Pupils may think that humans either grow at a steady rate throughout their lives or only grow on milestones such as their birthdays.

When pupils have completed their line graphs showing human height data, discuss the changes in height between different ages.

Data - In science, data is information collected during an investigation, which can include numbers, symbols, pictures, or text.
Mean average - A mean average is calculated by adding values together and dividing the total by the number of values.
Line graph - A line graph is a type of diagram used to show how a variable changes over time.
Plot - To plot a mark or line on a graph means to place it correctly on the axes according to its values.
