Bringing the world of energy into teaching

Welcome to the April 2008 edition of the E.ON Energy Experience e-newsletter for secondary science and geography teachers across England, Scotland and Wales. The newsletter aims to keep you up to date with the latest energy issues and relate these to your curriculum needs.

Current energy issues

Whose responsibility is it?

The government has committed to ensuring that every new home built in Britain from 2016 will be zero carbon. In addition, a report by the UK Green Building Council has concluded that all non-domestic buildings could be zero carbon by 2020.

Buildings are currently much the biggest source of pollution, contributing around 27% of all the country’s carbon dioxide emissions. Only a few hundred homes, and very few other buildings, are currently zero carbon. Half the country’s homes have less than a third of the adequate amount of loft insulation at present, despite two-thirds of Britons claiming that they are willing to pay more for an energy-efficient home.

The government has also laid down intermediate measures to ensure an improvement in energy efficiency of 25% by 2010 and 44% by 2012. However, Britain has lagged behind other countries in its commitment to reduce carbon dioxide emissions in non-domestic buildings, which contribute 18% of the country’s total carbon dioxide emissions.

Grants to help schools go green

By 2020, the amount of UK electricity generated by renewable technologies will have to rise to around 40%, from the current level of 5%, under ambitious plans put forward by the European Commission. The target, which is part of the wide-ranging EU climate and energy strategy, is double what the government had in mind until recently. The European Community as a whole is committed to sourcing 20% of its total energy demand from renewable sources by 2020.

Much of the expansion in Britain is likely to be met by wind energy, as wind technology is more advanced than other renewable technologies. Estimates suggest that the number of wind turbines on land in Britain is likely to increase from 2,000 to 5,000 and offshore turbines may have to increase from just under 150 to around 7,500.

However, figures published by the British Wind Energy Association have shown that a record number of wind farm projects were refused planning permission in Britain last year. Soaring costs, and objections from the Ministry of Defence that the turbines interfere with its radar, seem to be deterring developers from submitting new applications.

Students can learn more about wind power with the following activity:

Energy Saving Day disappoints

The UK’s first Energy Saving Day failed to register a noticeable reduction in electricity usage around the country. The day was organised by E-Day, which asked people to switch off electrical devices that they did not need over a 24-hour period starting at 6pm on 27 February.

National Grid monitored consumption over the 24 hours and found that electricity usage was almost exactly what they would have expected without Energy Saving Day. It is thought that a lack of publicity may have contributed to low participation levels. In addition, colder weather than forecast resulting in higher heating usage may have masked any small savings.

Use the following activities to encourage your students to consider energy-saving techniques around the home.

The new toy in town

The toymaker Corgi International has produced a revolutionary fuel-cell-powered remote-control car. The onboard hydrogen fuel cell powers the H2Go car, which only requires plain tap water to refuel it. The energy is achieved by electrolysis that splits the water into oxygen and hydrogen, which are captured and used to power the car.

The car also has a solar power panel and its packaging is made from recycled materials, which reduces the toy’s carbon footprint.

The makers say that this new generation of toy should lead the way for other industries to use opportunities to use clean energy fuel technology.

How Green is the Valley?

The Welsh Environmental Minister, Jane Davidson, has released plans that could make Wales self-sufficient in renewable energy within 20 years.

She said that wind, marine and biomass energy would be ‘sensitively, but extensively exploited’ in a similar way that Welsh coal powered the industrial revolution in the 18th and 19th Century.

The launch of the ‘Route Map’ towards a low carbon energy economy contains ideas to use wave and tidal energy with minimal disturbance to the environment.

Your students can understand how a country can reduce emissions, with a focus on wind farms, by undertaking the following activity:

Write ‘Renewable’ and ‘Non-renewable’ on the board. Divide the class into two teams. Ask one person from each team to stand a short distance from the board. Each team then takes turns to suggest a type of energy resource. The first person to ‘splat’ a correct answer on the board wins a point for their team. After every round the two people standing at the board are each replaced by a team-mate. The first team to score ten points is the winner.

Students can learn more about different energy sources in the following.

->14–16s: Energy sources

->14–16s: Where can we use it?

Lesson starters

Get your students focused on learning about energy by thinking about connections between the different sources of energy.

Audio to visual energy: Explain to students that you are going to describe a procedure to produce energy from one of the energy sources. While you are reading, pupils have to draw a diagram to illustrate what is being read.

Energy assemble: Get students to work in pairs to assemble in a logical order pictures to represent the formation of one type of energy e.g. solar. The pre-drawn/printed pictures could include a science apparatus, chemical symbols or parts of machinery.

Back-to-back chat: Get students into pairs and sitting back-to-back and give one of the partners a picture. The students then have to describe what they see to their partner. Their partner then has to draw what they hear. The picture could be a sketch map to show the location of wind farms in the UK or a diagram to show how light is converted in a photocell to electrical energy.

Suggested activities

Energy use now and in the future

Improve your students’ understanding of energy demands by having a go at the ‘Local to global’ activities on E.ON’s Energy World.

In the ‘Current energy use’ activity, students are asked to look at their average daily energy requirements by completing an interactive graph. They are asked to consider their use of electrical items in a typical day and their results are then compared to the UK’s average. The next section then allows students to compare the electrical demand in the UK to that in India.

The ‘Future energy use’ activity allows students to investigate the reasons for India‘s future increase in energy demand.

->14–16s: Local to global

Whose responsibility is it?

Ask for volunteers to take on the roles of a variety of different people, for example an energy company executive, a government minister, a householder who wastes energy, an environmentalist and so on. Each ‘character’ then takes turns to be in the hot-seat. The rest of the class should ask the characters about their attitudes, actions and responsibilities regarding various energy-saving issues. After questioning all of the characters, students then discuss who they feel needs to take responsibility for reducing energy consumption or whether the problem requires a joint response to reach a satisfactory solution.

The E.ON schools‘ energy conference

On 27 November 2007, young people from schools across the UK attended at the E.ON energy conference at the National College for School Leadership in Nottingham.

Throughout the day, the students took part in exciting activities, reported on their own research findings, and questioned energy experts.

The conference provided a unique opportunity for students to put forward their views on what they think individuals, government and energy companies should do to ensure energy is created and consumed properly.

“Just wanted to say a huge thank you for yesterday’s conference. Our two students came into school today absolutely buzzing – they had had such a good day... The accompanying teacher also had a very enjoyable experience with you. So all in all an excellent day!”

Feedback from a school in the South East which sent representatives to the 2007 conference

Curriculum changes

England

Under the new requirements for Key Stage 3 Geography, Section 1.6 Environment interaction and sustainable development, students need to understand that physical and human dimensions of the environment are interrelated and together influence environmental change.

In Section 2.1 of Geographical Enquiry, students are asked to solve problems and make decisions about geographical issues.

Within the Energy Nation (11–14) section of the E.ON Energy Experience website there is an activity called ‘The greenhouse effect’. Here, students can find out more about the causes of this phenomena via a drag and drop exercise. They are then asked to explore the effects of the human contribution to global warming whilst investigating the rise in sea levels.

->Geography Programme of Study: Key Stage 3

->11–14s: The greenhouse effect

Scotland

In the Environmental Studies 5–14 National Curriculum, section 2: Framework for Environmental Studies, under subsection 2.4 (skills), students are required to prepare for tasks (where they are provided with apparatus to think about problems, tasks and situations) and also to carry out tasks (where students are required to have the apparatus to explore materials and resources).

These two strands can be developed together using the Energy Nation section of the E.ON Energy Experience website, particularly ’The carbon tsar’ activity.

Here students find out about the effects of increased CO2 in the atmosphere, then carry out the task of reducing CO2 emissions from the production of power by locating a wind farm. This is done while considering the locational requirements of a wind turbine.

->Environmental Studies - Society, Science and Technology: 5-14 National Guidelines

->11–14s: The carbon tsar - Tackling the country’s carbon emissions

Wales

In the new Geography Key Stage 3 Skills section of the National Curriculum, there is a section which requires teachers to allow their students opportunities to ’explain how and why places and environments change’.

->Geography in the national curriculum for Wales

In the Energy Nation (11–14) section of E.ON’s Energy Experience website there is a section called ’Consequences of the greenhouse effect’. In this activity, students are introduced to the idea of climate change causing rising sea levels and their effect on coastal flooding in the UK. They are also presented with the same situation in Bangladesh and are shown how this country is dealing with this threat due to global warming.
