'Summarise data, from students’ own investigations and secondary sources, and use scientific understanding to identify relationships and draw conclusions based on evidence'
- constructing tables, graphs, keys and models to represent relationships and trends in collected data

For the Graphs below - Work in Pairs to:
- State what type of graph each is (eg. Bar Chart)
- Describe what the graph is telling us
- Create an Improved title for each graph
activity 1
activity 1
Write 3 sentences explaining what is wrong with the above graph
activity 2
activity 2
What can a graph tell us?
Write down three questions that someone could answer using this graph
Correlations
Correlations
A Correlation is a Link between two variables - it may not necessarily indicate a causal link as it may be coincidental - never the less - Scientists use graphs to visually display correlations and help them talk about these results
Activity 3
Activity 3
Independently answer the following questions about each graph below:
- What would the title of the graph be?
- What kind of Correlation do they show?
- Explain the Link between each variable (As x increases y....)

Graph 3

causation or correlation?
causation or correlation?
When two variables Link together there are times that people will believe they directly cause the change - if one variable changes then the other must also change. This is not always - and in fact very rarely - the case. Although the examples below can be viewed as quite humorous these can often be misinterpreted with dire consequences. Examples can be seen linking Vaccinations and Autism - this is a famous coincidental correlation - the result being many parents chose not to vaccinate their children despite their being no actual causation.
In the graphs below you should see some examples of correlations that are purely coincidental.
Write a paragraph about each graph explaining the coincidence. The first graph is done for you as an example
Graph 1 - Shark Attacks and Ice Cream Sales
Graph 2 - Fresh Lemons vs Highway Fatalities
Graph 3 - Global Temperature vs Pirates
Graph 4 - Cheese consumption vs deaths in bedsheets
activity 5
activity 5
There are 3 graphs for you to draw on GRAPH PAPER. They get more difficult.
- Once you have completed your graph, ask someone to peer assess it with a peer assessment sheet.
- Make any corrections you need to make and tick it off on the sheet in green pen.
- Try the next graph.
HINTS:
- If the independent variable is a word (like hair colour- blonde, brown, red, black) then you draw a bar graph.
- If the dependent variable is a number (like height) then you draw a line graph.
