Why are batteries important? Slide 1

Is your battery better? Is your newly designed battery better than others? Task: Design an advert to promote a new battery of the future Your advert should: • Describe the features of the battery (What’s it got that others haven’t? ) • Describe the advantages of this battery (How can it help me? ) • Describe the benefits of this battery (How will it be better for the environment/the world? ) • Be convincing about the battery (How do you know the claim is true? ) Slide 2

How do graphs help us to understand? Watch: An electric car accelerates faster than a petrol car The story as a graph: Quiz: What colour on the graph is the electric car? Think about: Why are two colours used on this graph? Slide 3

How do graphs help us to understand? The Story More expensive batteries generally outperform cheaper ones The story as a graph – Your turn to sketch! Sketch the line graph shape Challenge-Quiz Question Quiz: Does performance go on the horizontal (bottom) or vertical (side) axis? Think about: How do you decide what label goes where? Advanced batteries last 4 times longer than regular batteries and Ultimate batteries 8 times longer Sketch the bar chart shape Your advert Sketch a graph to support the story in your advert Quiz: Which bar is the tallest? Think about: Why is the graph a bar chart and not a line graph? Quiz: Name a real advert that use graphs, or charts Think about: Why do you think this is done?

What are the differences you can see? Compare & Contrast Think: Will electric cars go further if we use more batteries? Why have we not changed from single batteries in our most popular devices? Does bigger or more always mean better? Slide 4

What if you make a change? Interesting battery fact What if we make a change? A single lemon can be used as simple low voltage battery. What if we use two thousand lemons instead of one? The first mobile phone weighed 900 g. A typical phone today weighs only 100 g. What if we increase the future battery to weigh 30 Kg? A typical mobile phone battery lasts 10 hours before needing more charge. What if we remove the phone applications, e. g. camera, internet, music? Watch: 2016 was the first time a plane successfully flew around the world without fuel What if we used more solar power in everyday devices? Predict the consequences
