Pupils needing extra support

Could use the Activity: Transparency table template (support) to create a table for their results when testing the transparency of different materials; could be provided with the following ranges for lux in order to categorise their materials: opaque (decrease to 0 lux), translucent (decrease of more than 10 lux), transparent (decrease of 10 lux or less); could use the Knowledge organiser to help them define and sort transparent, translucent and opaque materials. 

Pupils working at greater depth:

Should test additional materials they find in the classroom; should add an extra column to their results table with the heading ‘Observations’ and record how the clarity of an object viewed through the different materials varies (for example, the object was clear, fuzzy, coloured, distorted, not visible); should suggest potential uses for the materials tested based on their transparency; could choose an extension activity relating to transparency from the Resource: Stretch and challenge: Properties and changes.
