Product Design 
Topic  MP3 Amplifier construction
No of lessons  12
What will students learn  Students  will learn how to produce simple systems diagrams (input, process, output) and be able to classify different components in those terms. They will extend their knowledge of electronic components to include the use of capacitors, integrated circuits and speakers. Students will learn how to connect off-board components. Students will learn to independently place and correctly orient components in preparation to soldering. Extension work: students will develop skills in isometric drawing. 
Key Knowledge that students should know at the end of 'Topic' This is the knowledge that students will meet for the first time in this topic  Students will be able to categorise  components in an electronic system  in terms of function and explain the function of resistors and capacitors in circuits. Students will be able to describe the advantages of using surface- mount technology. Students will be able to describe the impact of consumer electronics on the environment. 
This is knowledge that students may have met before but will need to deepen their understanding  Students will learn how to identify component values and understand what they represent (resistor colour codes etc . Students will be able to correctly identify the placement and orientation of components on a circuit board using a written set of instructions. Students will be able to draw and identify circuit symbols for the components used in their practical work. 
Key Skills that students should be able to demonstrate at the end of 'Topic' This is the skills  that students will meet for the first time in this topic Soldering techniques including health and safety measures (recap from year 7). Connection of off-circuit components (speakers). Students will be able to correctly identify components and place them in the correct locations on a circuit board and in the correct orientation where required.  Students will be able to prepare wiring for connecting off circuit component connection. Students will learn to follow a written diagnostic to identify and correct circuit faults.
This is skills that students may have met before but will need to develop  Students will be able to identify simple electronic components and their symbols. 
Key vocabulary that students should know and understand Soldering, circuit board, orientation, component. 
The Big Question  What contribution do electronic products have in our lives? 

 

 Key questions that students should be able to answer at the end of the 'Topic'

What are the main subsystems in an electronic circuit? 
What are capacitors and what do they do?
How can you identify which way round to place an electrolytic capacitor in a circuit board? 
What advantages do surface-mount components have over conventional components. 
Why are the advantages of surface-mount technology important in electronic product design? 
In order of importance, list the most common faults in constructing electronic circuits?
What is E-waste? 
Why is E-waste a problem and how could we address the problem?
