Mastering Science Skills: Graphs, Fair Tests, and More!
What do you already know about science skills?
Learning Objectives
At the end of the lesson you will understand how to plan fair tests, make accurate measurements, interpret scientific graphs, and use key science investigation skills.
What Are Science Skills?
Science skills help us investigate the world. They include observing, measuring, predicting, and using data.
Interactive: Share What You Know!
On your device: Write or draw what science skills you have used before. Teachers can view your ideas live.
Making Observations
What Is Observing?
Looking carefully at objects, events, or experiments to gather information.
How To Observe
Use your senses or simple equipment like a magnifier or thermometer.
Interactive: Mindmap
Build a mindmap on your screen: What things can you observe in a science lab? (e.g. colour, smell, temperature, etc.)
Why Do We Measure?
Measurements help us collect accurate, repeatable data. We use standard units to compare results.
Interactive: Drag and Drop
Drag the correct unit to match each tool: Ruler, Thermometer, Measuring Jug, Stopwatch.
Types of Variables
The one you measure.
Independent Variable
Dependent Variable
The one you change on purpose.
Interactive: Sorting Game
Sort these into "independent" or "dependent": Amount of water, Plant height, Light hours, Number of leaves. Teachers see results live.
What Is a Fair Test?
A fair test only changes one variable at a time. All other variables must be kept the same (controlled).
Interactive: Drag and Drop
Drag variables into 'change', 'measure', or 'keep the same' for the following experiment: Does temperature affect how fast ice melts?
Recording Results
Record your measurements in a table. Use clear headings, units, and organise your data for easy comparison.
Interactive: Fill in the Table
Complete a results table with data for a seed growth experiment. Teachers can view your completed table.
Understanding Graphs
Why Use Graphs?
Types
Graphs show us patterns and help us explain results.
Common graphs: bar charts, line graphs, pie charts.
Interactive: Match the Graph
See different graphs and drag experiment descriptions to match them. Teachers will see your matches live.
Making Conclusions
Conclusions explain what your results mean. Use evidence from your data to support your ideas.
Interactive: Write a Conclusion
On your device, use data from a sample experiment to write a conclusion. Teachers can view and give feedback.
Checking for Errors
Look for mistakes or unusual results. Ask: Did I measure correctly? Did something go wrong? Always double check your work.
Interactive: Spot the Error
Look at a sample table and graph. Mark any mistakes or things that seem wrong. Teachers can see your answers.
Peer Review
Science is stronger when we share and check each other’s work. Giving feedback helps everyone improve.
Science Skills Mindmap
Practise every investigation. Work carefully and check your results.
Key Skills
How To Improve
Observing, measuring, predicting, investigating, graphing.
Interactive Quiz Time!
Quiz: Multiple Choice
Choose: What is the dependent variable in an experiment? Teachers see your answers live.
Quiz: Long Answer
Write: Describe how to make a fair test. Teachers can review your answer.
Well Done!
You have explored key science skills. Try using them in your next experiment. Ask, measure, and investigate!

What software can be used to create graphs?
Word processing software
Email clients
Web browsers
Excel or Google Sheets
What is a pie chart best for?
Displaying trends
Comparing different categories
Showing parts of a whole
Counting data points
What must be included on your graph's axes?
Data points only
Legends only
Only colours
Labels and scales
Which type of graph shows trends over time?
Bar graph
Pie chart
Scatter plot
Line graph
What is the first step in making a graph?
Collect your data
Choose colours for the graph
Print the graph
Label the axes
What is a fair test?
All variables change at once
No variables are controlled
All other conditions remain constant
Only one variable changes
What is an independent variable?
The variable you change
It affects the dependent variable
It measures the outcome
It is kept constant
What is a dependent variable?
The variable you measure
It responds to the independent variable
It is changed in the experiment
It stays the same throughout
What are controlled variables?
They measure the results
They ensure a fair test
Variables that change during the test
Variables kept constant
Why is a fair test important?
It complicates the experiment
Ensures valid results
Reduces bias in findings
It makes results unreliable
Correct the order.
