The relationship between forces and motion is counter-intuitive and so needs careful explanation. Examples of energy going from one thing to another.Making Energy Real: Using the SEP Energymeter.We begin with simple experiments that introduce the language of energy, and go on to include more advanced topics such as the energy shared amongst the particles of matter - the internal energy in hot objects, often called 'heat'. Magnetic fields due to currents in wiresĮnergy is an abstract concept that requires lots of discussion with students about physical observations and their interpretation.Or magnetic materials used for computer hard drives, repeatedly magnetised and demagnetised at tiny length scales. We also include engineering applications of magnetism, such as the variety of clever electromagnetic machines used everywhere in industrial societies. These practical activities range from simple field patterns of bar magnets through to the laws of electromagnetic induction. Finally, there are collections dealing with electrostatic effects and electric fields. Experiments with AC circuits start from an introductory level and go on to include phase relationships. Next come experiments involving conduction through liquids and gases. Ionising radiations and their propertiesĬollections in this topic begin with simple DC circuits, introducing ideas about current, potential difference and resistance.They will experience the wonder of seeing the path of beta particles change when they pass through a magnetic field, and realising that even these invisible particles obey known laws of physics by moving according to Fleming’s left hand motor rule. Through the following collections of experiments in this topic, students can develop their own ideas of what is inside an atom. We also follow progress from the ideas of Copernicus to the predictions and explanations that followed Newton's theory of gravitation. We include observations of the night sky and demonstrations of the models which have been proposed to explain them. The following collections of astronomy experiments show how science explanations can be built from careful and systematic observations. The resources are part of the Practical Work for Learning project which explores how three different teaching and learning approaches can be applied to practical work. Practical Physics is part of a group of projects that include Practical Chemistry and Practical Biology. There are also a set of resources to support the teaching of practical science at key stages 3 to 5. Good quality, appropriate physics experiments and investigations are the key to enhanced learning, and clarification and consolidation of theory. Practical activities are not just motivational and fun: they can also sharpen students’ powers of observation, stimulate questions, and help develop new understanding and vocabulary. Most resources have been migrated over to this website - IOPSpark - from but if you find any mistakes or missing content, please let us know via. Many have links to carefully selected further reading and all include information and guidance for technicians. Some of the experiments can be used as starting-points for investigations or for enhancement activities. Index.Practical Physics is a collection of experiments that demonstrate a wide range of physical concepts and processes. These resources are for the use of teachers of physics in schools and colleges. Mosaic crystals and polycrystalline materials. Application of dynamical effects in single crystals. Diffuse scattering and absorption effects 13. Radiations and their scattering by matter.
