Lesson plan
Recap and recall
Display the Presentation: Sorting materials and ask the children to decide how to sort the materials into different groups, giving justifications for their decisions. Encourage the children to apply their knowledge of electrical conductors and insulators from the last lesson.

Adaptive teaching
Pupils needing extra support
Could use the Activity: Investigating bulb brightness: support to provide prompts when writing the enquiry question and forming a conclusion; should watch the Pupil video: Investigating bulb brightness to reinforce the method and offer reminders throughout the experiment as it is set to play on a loop.
Pupils working at greater depth
Should make predictions about different numbers of bulbs in a series circuit and the subsequent bulb brightness (therefore extrapolating data); could use an ammeter within the series circuit to collect quantitative data to support the relationship described; could use a device to access the link: PHET Circuit Construction Kit to simulate the addition of an ammeter into the circuit to collect quantitative data to support the relationship described.
