Using data loggers to collect data
Lesson details
Learning outcome
I can explain that a data logger collects data points from sensors over time.
Key learning points
- A data logger is a digital device that can automatically record data from sensors over a period of time.
- Data loggers take readings at set intervals (e.g., every 1 second, 5 minutes, or 1 hour).
- The timing of these intervals affects how detailed the collected data will be.
- Shorter intervals give more detailed data, but require more storage.
- Using this data, you can identify and explain patterns shown in the data.
Keywords
Logging - capturing and displaying or storing data points (usually over time)
Data point - a discrete piece of data, often part of a data set
Interval - the time between data readings
Common misconception
Shorter intervals give less detailed data.
If you were to take your temperature every minute, you would have more detailed data than if you took your temperature every hour because there would be more readings.
Teacher tip
Try using two different groups to collect data at different intervals. Compare the results to see the different effects of different rates of sampling.
Equipment
Pupils need access to data logging hardware and software.

We use learning cycles to break down learning into key concepts or ideas linked to the learning outcome. Each learning cycle features explanations with checks for understanding and practice tasks with feedback. All of this is found in our slide decks, ready for you to download and edit. The practice tasks are also available as printable worksheets and some lessons have additional materials with extra material you might need for teaching the lesson.
The assessment exit quiz will test your pupils' understanding of the key learning points.
Our video is a tool for planning, showing how other teachers might teach the lesson, offering helpful tips, modelled explanations and inspiration for your own delivery in the classroom. Plus, you can set it as homework or revision for pupils and keep their learning on track by sharing an online pupil version of this lesson.
