Read the data: climate graph and population pyramid
Interpret two invented datasets using graphs, calculations and written explanations. Pupils read a Brightwater climate graph and monthly table, then examine a population pyramid for an invented town, calculate totals and percentages, and justify a possible service need with data.

A teaching sequence
Read values from climate and population graphs, calculate with units and support an interpretation with data.
Brightwater: invented climate data for practice. Read rainfall bars and the temperature line using their separate axes.
Read the complete materialRead the invented climate axes and table
Read the invented Brightwater climate graph and monthly table for warmest month, extremes, range, wettest and driest months, total rainfall and summer mean.
Which scale and unit belong to the temperature line and rainfall bars?
Brightwater: invented climate data for practice. Read rainfall bars and the temperature line using their separate axes.
Read the complete materialDescribe the rainfall pattern with values
Describe the rainfall pattern using figures and note what more than one year would help explain.
What could further years show that this single invented year cannot?
Calculate from the population groups
For the invented town’s population pyramid, identify age groups and calculate the requested total and percentages with units.
Have you converted hundreds to people and used the correct total for percentages?
Propose a service through data
Suggest why older women may outnumber older men, then choose a service and justify it with data. Treat causes as hypotheses.
Which figure supports the need, and which causal explanation remains a hypothesis?
Before you teach
Look for the thinking behind an answer, choose the support your class needs and leave room for an independent response.
What to look for
Check that pupils use the rainfall axis for bars and temperature axis for the line, then include correct units. Verify arithmetic from the printed tables. For interpretations, look for a claim supported by a value and a sensible note about limits or additional information needed.
Give a little support
Provide a colour key or point to the two climate axes before pupils answer. Work through one table lookup and one percentage calculation. Let pupils annotate the graph and write a claim-evidence sentence before drafting a longer explanation.
Take the idea further
Ask pupils to compare the climate and population evidence and propose what additional data would strengthen a service plan. They can calculate a different age-group percentage or explain why a population pyramid cannot, by itself, prove a cause.
Things to keep in mind
Both datasets are invented and do not describe a real town or climate. A graph can show patterns but does not establish causes. Population categories and explanations are simplified; use additional context and reliable sources for real-world conclusions.
Keep the idea. Make it yours.

Good Question
The two-page worksheet pairs an invented Brightwater climate graph with an invented population pyramid. Pupils read temperature and rainfall from separate axes, calculate yearly summaries with units and then interpret age-group data.
Chalk & Chai
For ages 14 to 16, the climate section asks for warmest and coldest months, range, wettest and driest rainfall, total, mean and a two-sentence pattern. The population page shifts to reading a different graph form.
Planning List
Use the monthly table beside the climate graph to verify a read value before calculating. Pupils can label the axis used for each quantity, reducing confusion between the rainfall bars and temperature line.
Clear Example
Both datasets are invented for practice, not evidence about a real place. Keep that label in any extracted answer or graph, and support each interpretation with values from the correct axis.
