Assessment statement Obj Notes8.4.10 Outline the problems associated withproducing nuclear power using nuclearfusion.2 It is sufficient that students appreciate the problemof maintaining and confining a high‐temperature,high-density plasma.8.4.11 Solve problems on the production of 3nuclear power.Solar Power8.4.12 Distinguish between a photovoltaic cell anda solar heating panel.8.4.13 Outline reasons for seasonal and regionalvariations in the solar power incident perunit area of the Earth’s surface.8.4.14 Solve problems involving specificapplications of photovoltaic cells and solarheating panels.Hydroelectric power8.4.15 Distinguish between different hydroelectricschemes.2 Students should be able to describe the energytransfers involved and outline appropriate uses ofthese devices.232 Students should know that the different schemesare based on:• water storage in lakes• tidal water storage• pump storage.28.4.16 Describe the main energy transformationsthat take place in hydroelectric schemes.8.4.17 Solve problems involving hydroelectric 3schemes.Wind power8.4.18 Outline the basic features of a wind2 A conventional horizontal-axis machine isgenerator.sufficient.8.4.19 Determine the power that may be delivered 3by a wind generator, assuming that thewind kinetic energy is completely convertedinto mechanical kinetic energy, and explainwhy this is impossible.8.4.20 Solve problems involving wind power. 3Wave power8.4.21 Describe the principle of operation of an 2 Students should be aware that energy from aoscillating water column (OWC) oceanwavewater wave can be extracted in a variety ofenergy converter.different ways, but only a description of theOWC8.4.22 Determine the power per unit length of a 3wavefront, assuming a rectangular profilefor the wave.8.4.23 Solve problems involving wave power. 3is required.
8.5 Greenhouse effect 3 hoursAim 7: Computer simulation, spreadsheets and databases have a significant role here.Assessment statement Obj Notes8.5.1 Calculate the intensity of the Sun’s2radiation incident on a planet.8.5.2 Define albedo. 18.5.3 State factors that determine a planet’salbedo.1 Students should know that the Earth’s albedovaries daily and is dependent on season (cloudformations) and latitude. Oceans have a low valuebut snow a high value. The global annual meanalbedo is 0.3 (30%) on Earth.The greenhouse effect8.5.4 Describe the greenhouse effect. 28.5.5 Identify the main greenhouse gases andtheir sources.8.5.6 Explain the molecular mechanisms bywhich greenhouse gases absorb infraredradiation.2 The gases to be considered are CH 4 , H 2 O, CO 2and N 2 O. It is sufficient for students to know thateach has natural and man-made origins.3 Students should be aware of the role played byresonance. The natural frequency of oscillation ofthe molecules of greenhouse gases is in theinfrared region.8.5.7 Analyse absorption graphs to compare therelative effects of different greenhousegases.3 Students should be familiar with, but will not beexpected to remember, specific details of graphsshowing infrared transmittance through a gas.8.5.8 Outline the nature of black-body radiation. 2 Students should know that black-body radiation isthe radiation emitted by a “perfect” emitter.8.5.9 Draw and annotate a graph of the emission 2spectra of black bodies at differenttemperatures.8.5.10 State the Stefan–Boltzmann law and apply 2it to compare emission rates from differentsurfaces.8.5.11 Apply the concept of emissivity to compare 2the emission rates from the differentsurfaces.8.5.12 Define surface heat capacity C s . 1 Surface heat capacity is the energy required toraise the temperature of unit area of a planet’ssurface by one degree, and is measured in J m –28.5.13 Solve problems on the greenhouse effectand the heating of planets using a simpleenergy balance climate model.K –1 .3 Students should appreciate that the change of aplanet’s temperature over a period of time is givenby:(incoming radiation intensity – outgoing radiationintensity) × time / surface heat capacity.Students should be aware of limitations of themodel and suggest how it may be improved.Aim 7: A spreadsheet should be used to show asimple climate model. Computer simulations couldbe used to show more complex models (see OCCfor details).TOK: The use and importance of computermodelling can be explained as a powerful meansby which knowledge may be gained.
