PHYSICS


Years 7 through 8
Objectives and tasks
Physics teaching in primary school expands upon the integrated contents of the subjects ‘Environment’ and ‘Nature’ taught in lower Years. In primary school, the aim of teaching physics is drawing pupils’ attention to nature, and more specifically, to physical phenomena. This interest is instrumental in laying the foundation of further scientific literacy. Simple occurrences and practical examples are used to demonstrate that natural phenomena may be examined and understood through experiments, and that the knowledge obtained in this way can be used in everyday life. It is very important to make pupils aware of the fact that our knowledge in physics, through technological development, has a decisive effect on the quality of our life. At the same time, physics can also be used to protect the environment.

Physics classes will only become an interesting experience and therefore effective if the syllabus is focused on the demonstration of phenomena and contains many well-selected experiments. When introducing concepts and describing laws, technical, but as far as possible, simple language should be used. Abstract thoughts, which hinder rather than facilitate understanding, should be avoided. Of physical concepts, teaching in the primary school focuses on those which are linked to actual experimental observations and do not require too much abstraction.

If possible, the introduction of physical concepts and laws should always be based on observations, demonstrations or actual experiments. Here, attention should be paid to teaching pupils to become adept at precise observation of occurrences and at giving an accurate description of them. Experiments which pupils may carry out themselves are especially valuable.

Of the scientific subjects, physics is one which can make pupils understand already in primary school that natural phenomena can be denoted quantitatively, using the language of mathematics. In primary school, mathematical denotation, however, is limited to the simplest correlations – proportionality, inverse proportionality. But in these cases, it is very important to apply the laws learnt in simple mathematical examples. Beside practising, problem solving may also contribute to better understanding if the teacher present the pupils with problems where the data are determined appropriately in advance and where the result can be controlled through experiments. Such problems make pupils realise that physics problems are not simple mathematical problems but descriptions of nature, which give real, measurable data as result. Apart from problems where calculation is necessary, the solving of qualitative problems appropriate for the knowledge level of the pupils is also important in developing physical thinking. These may include questions concerning the explanation of everyday phenomena or the interpretation of an experiment seen in the classroom.



Developmental requirements
Learning, knowledge processing and application skills
Pupils should have the ability to consciously observe physical phenomena and processes while observing previously defined aspects, strive for their understanding and differentiate between material and unimportant factors.

They should be able to present the findings and the results of the experiments in various formats (tables, graphs, schematic drawings), as directed by the teacher. They should be able to read and interpret data from graphs, tables and schematic drawings, and make relevant simple conclusions.

They should coherently describe and explain physical phenomena, laws and related practical applications thereof on the level appropriate for their knowledge.

They need to execute simple experiments and measurements, and be adept at using the experimental materials and tools safely.

They should be well-versed in using SI units of measurement covered in the syllabus, as well as non-SI measurements commonly used; also, they should be practised in converting units of measurement used in everyday life.

The need to be able to peruse various lexicons, collections of formulas and tables and multimedia educational software in accordance with previous instructions. The need to be aware of the availability on the web of data and information helpful for physicians. They should understand the information contained in books, articles, TV and radio programmes corresponding to their level of intellectual development, and be critical towards ‘sensational novelties’ and hypothesis lacking scientific evidence.

They should appreciate the beauty of nature and know that we are responsible for the protection of nature and the environment. They should be familiar with the conservation and environmental aspects of the syllabus, and make efforts for their utilisation.
Familiarity with matter, orientation in space and time
They should recognise the attributes – covered in the syllabus – of materials found in their natural and man-made environment, and be able to group materials by the attributes covered.

They should know that natural phenomena occur in space and time, and that physics is concerned with instant occurrences in invisible microcosms, just like changes in stellar systems, which take millions of years to happen.

They should be adept at estimating distances and durations encountered in everyday life, as well as their comparison, and have an understanding of the orders of magnitude found in nature.
Familiarity with scientific learning and the evolution of science
Pupils should be aware that scientific learning is a long process, and hat what we know about the physical world is much more than what was known in previous centuries, but certainly much less than what later generation will know. With respect to pieces of physical knowledge covered, pupils should know in which era major breakthroughs were made, and by whom. They should be familiar with the work of outstanding Hungarian physicians, engineers and scientists.

They should understand that physics and other scientific disciplines are closely interrelated, and that though they apply different methods to investigate different aspects, they explore the same physical reality.
