KS3 Resistance in Circuits

This resource was designed for a top set year 8 class studying an electricity topic.

This resource requires the following practical equipment:

• One large rope for demo
• Power packs
• Crocodile clips
• Wires
• Bulbs
• Ammeters
• Resistors

This PowerPoint resource contains:

• A “5 in 5” retrieval style starter on current, potential difference and insulators
• A retrieval practice task on giving definitions for key terms (current, potential difference, ammeter, voltmeter, electrons)
• Direct instruction on resistance with dual coding
• A hand signals quiz to check for understanding
• A simple ‘fill in the blanks’ task with delayed key word bank
• A rope model demo for current and resistance
• A discussion task about the model - what did each person represent?
• A practical activity on the effect of resistors on current in a circuit (results table provided as print out)
• A plenary task (writing a conclusion for the investigation)
