S1 & S2
A bright Idea
Look at the First 2 images below ( Light bulbs and Powerboard)
Create a Keynote or Powerpoint that answers the following questions)
Lightbulbs
Q1 What are the 3 types of common lightbulb?
Q2 How are they different in the way they operate.
Q3 Which lightbulb is the most energy efficient?
Q4 which lightbulb is not sold in shops anymore and why?
Powerboards S1 &S2 & S3
Electrical overload
Q5 What is surge protection on a power board and why is 25 nanosecond switch off time very important?
Q6 This power board is rated at 2400Watts - what does this mean in terms of energy consumption?
Q7 This power board has switches and others do not - why is having individual switches a good safety feature.
Q8 CHALLENGE - You want to buy a power board for your office. You will have a computer, monitor, printer modem and want to charge your phone. The office has a single powerpoint. The Computer monitor has a larger than normal transformer plug. Go online and try to find a solution to your energy problems.
S2 & S3
Consumer electricity
Q9 You are buying a Fridge and a Dishwasher. Your fridge must be as energy efficient as possible because it is always turned on but you use the Dishwasher only twice a week so it can be inefficient. Do some online shopping and find each appliance and explain the difference in energy efficiency in terms of the energy sticker they come with. There is a link below that has an example of an energy label to help you.
Q10 You have received your first energy bill which is available online using the link below. Show evidence that you know what the sections labelled 4, 5 and 9 represent.

S3 Only
Electricity in the home
Create a multimedia presentation that showcases the properties and functions of the 6 photos above.
Include these or similar images and use electrical terminology such as Watts, Power, energy, voltage, current, Earth, Active, Neutral, Circuit Breaker.
The following 2 websites will help explain the last two pictures
S4 Only
Camping off the Grid
Create a poster that showcases the energy requirements of a camp site that relies on only Solar Power.
You must provide enough power to run a fridge, lights and small TV using solar panels.
Include key words in your presentations such as Voltage, AC/DC, energy efficiency, voltage regulator, Deep cycle battery, kiloWattHours ( kWh)
This task requires some mathematical understanding of battery charging and discharging and energy usage in terms of kWh. It should include graphs of energy efficiency of a deep cycle battery and discharge rates depending on electrical load.
If you choose this task and only describe what is required for a campsite and NOT the electrical energy requirements then you will not be assessed at a satisfactory level - THIS IS A WISDOM TASK and the level of information must justify the assessment.
A link to camping information is provided below.
