Pupils who are secure will be able to:

• Describe the function of key electrical components and explain how the models used in the lesson represent these.
• Correctly predict if an electrical circuit will work or not, explaining why using their knowledge of complete loops, power sources and presence of components.
• Describe the relationship between the number of bulbs in a circuit, the bulb brightness and the amount of resistance.
• Explain that increasing the number of components increases the resistance, affecting the flow of current and energy transferred.
• Identify that batteries are a voltage source; they come in different voltages, affecting bulb brightness.
• Describe that voltage can be changed using different numbers of cells in a circuit and that more cells or a higher voltage causes brighter bulbs.
• Use the relationship between voltage and bulbs to predict what will happen with buzzers and motors.
• Build an electrical circuit with a switch to control its function, explain how the switch and the electrical circuit solve the problem and recall different examples of problems that can be solved using an electrical circuit.

When working scientifically, pupils who are secure will be able to:

• Draw circuit diagrams with straight lines and using standard circuit symbols.
• Design a results table with an appropriate number of columns and headings with units.
• Identify the changed, measured and control variables in an enquiry to plan a method.
