These resources will be removed by end of Summer Term 2025.
Switch to our new teaching resources now - designed by teachers and leading subject experts, and tested in classrooms.
These resources were created for remote use during the pandemic and are not designed for classroom teaching.
Lesson details
Key learning points
- Increasing the number and voltage of batteries increases the electrical push they provide.
- Test results help scientists to make predictions for further investigations.
- Sensors and data loggers can be used to make and record accurate measurements of light and sound.
- Scientists evaluate results to compare what was expected to what actually happened.
Keywords
Variables - A variable is a factor that can be changed in an investigation.
Component - A component is a device in a circuit that has a specific function.
Predict - To predict is to say what you think will happen.
Buzzer - A buzzer is a device in an electrical circuit which makes a noise.
Decibel - A decibel is a unit used to measure the volume of sound.
Common misconception
Children may not understand how variables interact within a circuit and how changes in one variable can affect others.
Teaching slides will relate the need to control variables in a fair test to the need to do so with circuits in order to be able to relate a given variable to a measured outcome.

The starter quiz will activate and check your pupils' prior knowledge, with versions available both with and without answers in PDF format.
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.
