This is the time of year when CLEAPSS receives lots of calls to the Helpline about fireworks. We get asked about activities and experiments that teachers can do with their pupils in school. CLEAPSS would always urge caution and we have produced a new guidance leaflet, PS81 Fireworks and explosives. Although written more for teachers and technicians in secondary schools the document provides useful background information about the legal issues involved. Also included in the leaflet is a list of references and resources that could be used by primary science coordinators to inform project or topic work on fireworks and firework safety. A selection of the references is given here: www.fireworksafety.co.uk Www.hse.gov.uk/explosives/fireworks/ www.gunpowder-plot.org www.royalgunpowdermills.com Q. Can children take home battery-operated electric buggies or other items made in class? A. Although tempting to send children home with the things they have made, you really need to think it through! It is impossible to predict what might happen to the treasured objects after they leave the classroom. Younger siblings may get hold of them - are they safe to be chewed or ingested? Do they have bits which may come off and result in a small child choking? You may have taken scrupulous care with hygiene when preparing food or making bath bombs, for example, but can you be sure that things won’t be eaten or handled by someone with food allergies or sensitive skin? Think it through - do a risk assessment and, if in doubt, give CLEAPSS a call. Q. Where can we get copper(II) sulfate for our ‘Gifted & Talented’ club? A. Primary catalogues have, generally, dropped their chemical lists in favour of ready-prepared kits for various activities. It is usually better to avoid hazardous chemicals (copper (II) sulfate, for example, is HARMFUL if swallowed and IRRITATING to eyes and skin) and stick to substances available from a supermarket, pharmacy or hardware store. There may, however, be occasions when it is appropriate for (well-supervised) children to carry out an activity using materials that are not generally available and that are possibly HARMFUL or IRRITANT. Other hazardous substances (e.g. TOXIC or CORROSIVE) are best avoided in primary schools. Several educational scientific suppliers have assured CLEAPSS that they would be happy to supply reagents from their secondary catalogues to primary schools on request. View the details on your supplier’s website or contact the sales team. Make sure that you have secure, suitable storage for any hazardous chemicals. Be sure too that you are confident about handling the chemicals and know how to dispose of them at the end of the activity. CLEAPSS guide L5p Safe use of household and other chemicals is full of useful information and ideas. Q. Help - I’ve broken a mercury thermometer! A. Luckily the teacher had used it in a tray which contained the broken glass and the mercury. The caretaker had then covered the tray to avoid further spillage and to contain vapours. We suggested calling a local secondary school to ask if the technician there could treat the spill and remove the residues for specialist disposal. Mercury is TOXIC. Small globules of the metal find their way into cracks so it is important to ensure that all traces are safely removed. Mercury also attacks other metals, so wear disposable gloves to avoid contact with any jewellery if you do need to clear up after a breakage. The use of mercury thermometers in primary schools is discouraged as safer alternatives are readily available. Contact CLEAPSS if you have any queries or concerns.

Where are all the bees? This year’s appalling summer has led to a shortage of British honey and honeybees are under threat from parasitic diseases and the puzzling ‘colony collapse’ disorder. HSE at the 2008 CLEAPSS Safety Conference One of the main speakers at this year’s Safety Conference for Local Authority officers was Lorraine Shepherd of the Health and Work Division of the HSE. Lorraine spoke authoritatively on the subject of sensible risk management, which is currently a particular focus for the HSE. Among the points that Lorraine made were: • Children need risk in their lives. If we don’t provide it they will go out and find it. • Children should not avoid risk. • Properly managed science experiments do not pose significant risks to children. • Health & safety is about saving lives and stopping people from becoming injured or sick at work. • Don’t concentrate on trivial risks. Health & Safety law does not require action for trivial risks (see the Management Regs ACOP para 13 (a) – insignificant risks can usually be ignored as can risk arising from routine activities associated with life in general). • Generic risk assessment has to be adopted and adapted to suit local circumstances. Apparently there are no wild honeybees in Britain, every bee you see is from a managed hive and the number of beekeepers is also falling. Bees are so critical to the pollination of plants that there have been some wild claims that, if the honeybee were to die out, mankind would follow in four years because many food plants would not survive! This overlooks the many wind-pollinated food plants - especially the cereals - which are not dependent on insect pollination. Nevertheless, there is an environmental threat; and it’s one that children can understand and begin to do something about. The British Beekeepers association has developed a schools pack for Key Stages 1 and 2 which is a useful tool for teaching about the plants and animals that surround us, minibeasts, pollination and care for the environment. The resource (revised in 2008) is available in two formats - as a conventional ring binder or as a CDROM. It is full of lesson ideas appropriate across the primary age range. It costs £15 (including post and packing) from the BBKA (see below). These are all points that we support and which form the basis of our work with schools. A main message remains much as it did the last time an HSE officer spoke at our conference. Because it is well managed, school science is safe (so too is school design & technology). The use of generic (or model) risk assessments, modified to meet local circumstances, involves teachers in thinking how best to prepare for practical work and to teach pupils safely and effectively. Risks are ever present in all of our lives. In schools, by focusing on real risks and not those which are routine or trivial, staff can concentrate on helping pupils learn and not be diverted into unnecessary paperwork. And so say all of us! The CD version is structured as a self-contained website - so no Internet connection is needed. There is a teacher support section and an interactive ‘classroom’ that children can browse themselves. This version costs £10. Order forms for both products are at: www.bees4kids.org.uk Local beekeeping organisations will have enthusiastic and well-resourced beekeepers who are experienced at presenting in schools. This might be an ideal science club activity but do carry out a risk assessment first - a small number of people may have a severe allergic reaction to bee stings. If in doubt then contact CLEAPSS for advice. The HSE is keen that the many myths about health and safety are debunked. They have a website www.hse.gov.uk/myth/ index.htm which is a great source of cartoons about several of the more common myths. A new cartoon is produced each month and they can be downloaded and printed out as colour posters. The cartoon shown here is from August 2007 and highlights the myth about egg boxes being banned from use in craft lessons!

Food Chains Have you discovered the food chain mobiles (freshwater and garden) on the CLEAPSS Primary science website yet? Look for E243p and E244p. SAPS! The Science and Plants for Schools (SAPS) website www-saps.plantsci.cam.ac.uk has some great ideas, activities and resources for use in primary schools and is well worth a look. 4 AUTUMN 2008 PST Task Sheet 01: A burning candle CLEAPSS will soon republish guide L5p on materials. These teacher notes are adapted from that guide. A wax candle is a solid fuel. Heat melts the wax to a liquid which then evaporates to a gas. The gas burns to produce light and heat and two waste products – water and carbon dioxide (and, sometimes, some soot). When a candle burns, the exposed wick becomes longer and begins to smoke. The longer the wick, the larger the flame and the faster the candle burns away. Once, special cutters were used to trim the wick; but, in 1825, a monk named Cambacéres invented a wick that bends over. It pokes out of the unburnt gas into the air, where the tip burns away. The black part of the wick, inside the candle flame, is not exposed to air, and so it only slowly chars. Modern candles have a self-trimming wick. Candles are extinguished by removing the fuel (blowing the wax gas away - an oil rig fire is extinguished by an explosion); removing the oxygen (snuffing) or by making the temperature too low for the wax to burn (chilling). Children can: observe a burning candle safely at close range; learn that candle wax is a solid fuel; understand that a burning candle emits both heat and light; use vocabulary such as: ‘candle, wax, wick, light, flame, burn’; observe and describe the colours in a candle flame (the bluish unburnt candle wax gas and the yellow / orange burning wax); possibly observe and describe the black soot produced at the tip of the flame; notice that hot wax runs and is liquid – and possibly that very hot wax vaporises and is a gas; notice how the candle’s wick is burnt away outside the flame; learn that the candle is permanently changed; understand that the candle has been burnt away – and that burning is irreversible. Note: the relationship between a container’s size and the time a candle takes to go out is not a simple one. The candle may not be extinguished by a lack of oxygen; more likely it is put out by a falling ‘blanket’ of carbon dioxide. CARE: Tea light or night light candles are more stable than traditional candles. They should be used in a metal tray containing a layer of clean sand and lit only by the teacher. CARE: The children should be warned that the burning candle is VERY hot. They should tie back long hair, do up loose clothing and they must not lean over the candle flame. What will be needed: A tea light on a layer of sand in a metal tray or tin lid (pupil). A stopwatch or timer (pupil). Matches and two sizes of jam jar (teacher). A burning candle What to do Put a tea light in a metal tray of sand then ask your teacher to check it and to light it for you. ♦ Watch what happens What happens to the solid wax? What happens to the wick? Is the wick straight – or curved? Does a curved wick bend outside the flame? What happens when the wick is in the air outside the flame? ♦ What colours can you see in the flame? Can you see the unburnt gas? Can you see the glowing, burning gas? Is there black soot at the tip of the flame? Your teacher will carefully hold a jam jar above the flame. ♦ What can you see? Is there black soot on the jar? Are there drops of water? Where are they from? Your teacher will lower the jam jar over the candle. ♦ What happens? Why? What can you see in the jar? What might happen with a bigger jar? Why? Finally - time how long the candle burns in a small jam jar and then predict how long the candle will burn in a large jam jar. Your teacher will lower the big jam jar over the candle. Say ‘Now’ when you think the candle will go out. Were you right? PST number 42 5 AUTUMN 2008 Making time for monitoring Teaching another class can give you a good idea of that group of pupils’ understanding and skills development. This approach requires careful planning and you will need to establish how your lesson fits in your colleague’s plans and what to expect in terms of the children’s knowledge and skill development. Science co-ordinators often find monitoring the most challenging part of their role. Good monitoring tracks continuity and progression and should ensure that the teaching and learning experiences of a school’s pupils are of a consistently high quality. Is your focus really on the teaching and learning? A clear focus is essential; decide before you start what it is you are monitoring. You can’t possibly monitor ‘science’ but you can look at specific issues such as questioning or recording. If things aren’t as they should be then you can identify and tackle individual areas of concern. This will be a test of you as a curriculum leader - if it goes poorly, it may damage your credibility. If it goes well - don’t expect applause. You are, after all, the science expert! An alternative tactic is the 10 minute swap. Agree a time with another subject coordinator to swap classes. Aim to ask the children questions about their recent science experiences, their skills and learning. You could formalise this by asking them to complete concept maps on a given area of learning. Meanwhile, your colleague can do the same with your class for their own subject area. You can exchange your findings later. What's on the wall? Displays should illustrate a school’s achievements and qualities. This, after all, is children’s work thought worthy of wall space and is there to encourage and motivate. The walls will also tell you something about the range of science experiences in the school; and about the profile and status of science as a subject. I'll be watching you! How do you best use a lesson observation? Trawl the books A familiar aspect of an OFSTED inspection is the request for pupils’ books and these can cast light on learning, especially if viewed positively. One effective tactic is to look at a representative selection of children's work and evaluate what is good, and what can be improved on. There may be justification in some teachers feeling ‘overobserved’ so any monitoring by lesson observation needs sensitive management, good planning and clear intentions if it is not to be seen as a burden. Monitoring by lesson observation may already be part of the school’s approach to self-evaluation. It should be seen as a way to maintain standards, share ideas, support staff, and, in science especially, as a contribution to the management of health and safety. The AKSIS project established the ‘commentary’ as one approach to evaluating pupils’ work. For example, if monitoring a science enquiry, you would first establish the age and year the children are in and then look at their work with a view to answering a number of questions. Agree, well in advance, what the focus of the lesson observation will be and draw up a short lesson observation checklist with the teacher concerned. Remember, five questions thoroughly explored will be far more useful than fifty ticked boxes. Whose enquiry is it? What is the context? What question are the pupils trying to answer? Do they make predictions? Are they doing ‘fair tests’? Is it clear why? Do they draw conclusions? How good is their evidence? Has safety been considered? What help is the teacher’s marking - if any? Agree if you will be there purely as an observer, or whether you are to be actively involved in the lesson. The latter is less threatening to the teacher and also less confusing to the children. You can also learn a lot more by talking with and helping the pupils. As soon as possible after any observation, the class teacher should receive feedback and a copy of the observation notes. Agree actions for improvement and file the notes to inform future monitoring. What level is this? Consider the next highest level - how could children work towards that level? How could they improve? What help could be given when marking? What would improved work look like? Conclusion Sensitive monitoring leads to a review of practice, the audit of resources and policy, and provides a general insight into the strength of science teaching across the school. After evaluating several pieces of work in this way, it will be possible to give advice to individual teachers on how to improve the teaching and learning in their lessons. You will also have gained an impression of the strengths and weaknesses across the school. Good quality, effective monitoring demonstrates a wholeschool commitment to self-evaluation and to improving standards. Remember, however, that this approach only evaluates the written work which is a reflection of the teaching and learning in science.

PST number 42 6 AUTUMN 2008 Theoretically, it might be possible to design written tests that identified these sub-levels. Some published commercial tests claim that degree of accuracy - but do they deliver it and can you trust the results and/or use the information constructively? Sub-levels in science Are they desirable or even achievable? Primary language and mathematics both have sub-levels – so why not primary science? Teachers need to demonstrate progress and head teachers are under pressure to demonstrate effective schools and schools are aiming to track the science progress of individual pupils. From these demands has come the feeling that, perhaps, we should be able to place every child on a theoretical step of the ladder for each of the four science attainment targets. So what can teachers do? If you are asked to provide sub-levels, you could use your professional judgement to interpret any test results. “What a pity, Carl missed a Level 3 by just a couple of points. I think (and my classroom observation bears this out) that Carl is close to a Level 3. I’d certainly put him at 2+.” Or: “Danni did well. She surprised me. I’d have put her at just above Level 4 (say 4+), but she cracked a couple of the higher level answers. Certainly judging from her science book I’d call her a very good Level 4, but not quite a 5 yet. I think I could say she’s at level 5 –.” Combining your knowledge of the children with test results will enable you to plan more effectively. It may lead you to setting and grouping the children, but all decisions should put their learning first. Secure evaluation will lead to sound teaching and learning. This is far better than relying completely on a paper or digital test which probably won’t accurately reflect the individual child or the teacher’s own assessment. Against this, QCA does not appear to recognise sublevels; they don’t formally exist and QCA doesn’t encourage their use. In addition, the level descriptions are not designed to do this either; instead they present a general picture of ‘a child at Level 3’, for example. In practice, it could be possible to judge that a child is just better than one particular Level or is approaching the next. This could be expressed as + and –; as in Level 3+ or Level 4–. A third sub-level is used in maths and language - expressed as a, b, c. How achievable are sub-levels in science? In science the levels shade into each other. For example, how does ‘they use simple equipment provided’ (L2) differ from ‘using a range of simple equipment’ (L3)? Perhaps they use more kit at L3; but what kit and how isn’t clear. So how do you measure it? Is a child who is good with a ruler and timer at level 2 but another, who can read a thermometer, at level 3? The description doesn’t tell you – and it doesn’t set out to. In practical activities, differentiation is very difficult. Suppose you have decided the following: Level 3c = recognises that magnetism is ‘concentrated’ at the poles of a magnet Level 3b = can name the poles North and South Level 3a = knows that like poles attract and unlike poles repel? You then give the pupils some magnets to explore. How can you stop them discovering all these things – and a lot more besides? And should you? Indeed, how can you recognise and record these differences in a class of more than thirty? It’s worth asking yourself, ‘If I was confident that a child was at level 3 and the test only gave them a level 2, what would I actually record?’ Maybe you would go for an in-between score; although your professional judgement should count for at least as much as a child’s test performance on what might have been an off day. What should be hoped for is that, for example, a pupil who is at Level 2 in year 3 makes sufficient progress to be ‘a secure Level 3’ in year 4. A combination of professional judgement and a result from a reliable test should confirm this improvement. This article has been written by CLEAPSS’ Primary Science Consultant.

BA Festival of Science 2008 Like us, you may not have made it to this year’s Festival of Science organised by the BA (British Association for the Advancement of Science) and held in Liverpool. However, it is worth having a look at the festival website www.the-ba.net/the-ba/FestivalofScience/index.htm as well as visiting the BA’s home website www.the-ba.net/the-ba/index.htm for information about what went on at the festival and for useful links to science news, ideas and activities for young people. In maths and language the situation is quite different. Addition can be differentiated into adding two units, adding three units, or adding a string of units. Spelling can be eternally subdivided, from very simple words to hard ones. Differentiating the ideas in science is much more difficult. Curriculum time is another issue. Most schools might give two hours a week to science – if that. This is a very short time in which to collect the evidence to argue that Pupil A is a shade better than Pupil B … and be fair to both children.
