The Really Useful Science Book: A Framework of Knowledge for Primary Teachers

Language: English
Pages: 240
ISBN: 0415385938
Format: PDF / Kindle (mobi) / ePub
Written for classroom teachers and those in training, this book has been designed to support and extend teachers' and students' own knowledge and understanding of science, and should be of particular use to non-specialists.
Throughout the book every effort has been made to interpret the ideas and concepts of science in user-friendly language, using everyday activities as illustrations. The book is divided into three sections:
- life and living processes
- materials and their properties
- physical processes.
Key ideas are suggested for each section and then expanded to include important related science concepts. The book provides comprehensive knowledge for science at Key Stages 1 and 2, and sets the scene for teaching and learning at Key Stage 3.

bones, e.g. the ‘discs’ of cartilage between the vertebrae of the spine. The most obvious piece of cartilage which can be ‘felt’ is the end of your nose! Ligaments are strong elastic groups of fibres which bind the bones tightly together at joints and help to prevent them from dislocating. The joints themselves are enclosed by a synovial membrane which secretes synovial fluid which lubricates the joint. Over-use of a joint can cause the over-production of synovial fluid, causing painful swelling
placed in a container of fresh water it will sink. The density of the egg will be about 1.1 g/cm3. If enough salt is dissolved into the water, the density of the solution will increase until eventually it is higher than that of the egg, and the egg will float to the surface of the solution. This increased density of salt water is also part of the explanation for people feeling that they ‘float better’ in the sea than in fresh water. A similar experiment can also be performed with ‘centicubes’,
meanings is being used in any particular context – do we mean plastic the material, or plastic the property ? – and a careful use of language, will help to avoid confusion. Compressibility All materials have some ability to be compressed into a smaller space, although the compression of substances in solid and liquid states is usually too small to be obvious. Substances in gas state, however, can easily be compressed, and this characteristic can readily be experienced by attempting to work a
answer to the question ‘Is a seed alive?’ is ‘We do not know’ – at least, not until we have restored normal growing conditions to see if the seed germinates. An example of suspended animation from the animal kingdom would be the desiccated egg cysts of brine shrimps (sold commercially as ‘sea monkeys’). These cysts appear to be completely inert and can withstand years of desiccation, only to ‘come to life’ when rehydrated in the correct saline conditions. Perhaps the most crucial idea relating to
towards the Earth, at a terminal velocity which reflects the mass and shape of the object concerned (see Fig. 4.21). A ‘personal’ experiment may help here. Stand facing a wall at a distance of about 50 cm, and place your hands flat against the wall at about shoulder height. Gently bend your elbows so that you lean against the wall slightly, and then push against the wall to recover your original position. You should have performed a ‘standing-up’ press-up against the wall. The wall has provided
