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
- The physical properties of materials can be tested.
- A material’s density can be calculated by comparing its mass and volume.
- A material's absorbency can be measured by taking the wet weight away from the dry weight.
- Electrical conductivity of materials can be tested circuits to show whether a material is a conductor or an insulator.
Keywords
Density - a measurement of mass per unit volume
Absorbency - the ability of a material to soak up liquids
Electrical conductivity - the ability of material to allow electricity to flow through it
Common misconception
Absorbent materials hold water on their surface.
Absorbency involves the liquid being drawn into the material.

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.
