Lesson details

Key learning points

  1. Scientists can use graphs to represent data visually and make it easier to understand.
  2. Human height can be measured and plotted on a line graph to show how height varies with age.
  3. Findings from enquiries can be used to make further predictions.

Keywords

  • Data - In science, data is information collected during an investigation, which can include numbers, symbols, pictures, or text.

  • Analyse - To analyse data is to examine it carefully in order to explain or interpret patterns, trends, or relationships.

  • Bar chart - A bar chart is a type of diagram that visually represents data using rectangular bars.

  • Line graph - A line graph is a type of diagram that can be used to show how a variable changes over time.

  • Prediction - A prediction is a statement about what is expected to happen.

Common misconception

Pupils may not recognise the value of representing data on graphs or charts and might view it as just another task to complete.

Using the lesson resources, clearly explain the value of presenting data in a chart or graph and how it makes information easier to understand.

This lesson builds on previous learning about representing data in line graphs from lesson 7. Encourage pupils to relate their graphs to their own lives and explore whether they can use the graphs to predict how tall they might be at different ages.
