Years 7 and 8
Objectives and tasks
Chemistry in primary school expands upon knowledge and skills gained through the earlier subjects of Environment and Nature to introduce children to the discipline of chemistry.

Chemistry teaching aims to familiarise pupils with the diversity of materials, both in terms of material properties and the reactions occurring between various matters. Through categorising these occurrences, pupils need to be shown that these can be understood and handled with the help of a few simple principles. Examples from everyday life should be used to demonstrate both diversity and the efficiency of categorisation.

Pupils need to be shown the role of chemistry as a companion discipline of physics, biology and geography. It is important that studying nature by different criteria lead to the appearance of chemistry as an independent scientific discipline. The most important thing is to differentiate between physical and chemical properties and between life functions and chemical processes.

Pupils will be shown that chemical industry is an essential pillar of our modern technical civilisation. Also, their attention should be drawn to the fact that chemical industry has significant negative environmental effects, but also offers possibilities for environmental protection.

Well-designed chemical experiments serve learning through hands-on experience and enhancing interest in natural phenomena. Experiments should be spectacular but simple. There should be several experiments which pupils may reproduce at home (e.g. solution, combustion, acid and base reactions, fermentation). Through executing a large number of experiments, pupils should become accustomed to working with tools and materials accurately and carefully, and to be open to all observations. Interpretation of phenomena offers the possibility to develop problems-solving skills, and also establishes a desire to explain phenomena in the pupils. Also, they need to view saving energy and material as one of the efficient ways of environmental protection.

The introduction of abstract concepts and terminology in the primary school requires exceptional caution. The microcosm of atoms and molecules should be introduced in such a which manifestly help understanding chemical properties and reactions. Molecular models and crystal models should assist in the visible representation of the spatial relations of invisible particles.

Molecular models should also depict stable mass proportions. The interaction of nuclei and electron should help interpret the energetic aspects of chemical reactions. The periodic table is based on the structure of elements, but pupils should also be shown that it helps orientation with respect to the properties of simples elements.

By learning about inorganic materials which play an important role in our everyday life, pupils gain much knowledge about materials, and their experimentation skills also greatly improve. A portion of materials and their properties only becomes known to them on the level of term and concept, without the need for familiarity with reasons. Their knowledge, however, enables them to explain certain properties of materials, they understand the correlations between structure, characteristics and application. Pupils should become familiar with frequent chemical substances used in the household, as well as their physiological effects and safe application. They should hear about foodstuffs, poisons, drugs and their negative effects. Their attention should be drawn to the dangers of unhealthy substances, as well as the elements of leading a healthy life. Chemistry teaching in the primary school should primarily highlight the dangers of smoking and of abusing narcotic solvents which are readily available to this age group.

Starting with everyday materials and their changes, pupils should become familiar with categorisation, meaning essentially the ability to distinguish between mixtures, compounds and elements, on one hand, and physical and chemical transformations on the other. Reactions should be described using stochiometrically correct equations.

In the primary school, it is a basic task to teach pupils the adept at use of the balance of materials as expressed in chemical equations, as well as relevant units of measurement, and to teach them to use them routinely in problems involving quantities in reactions.

As far as possible, chemical syllabus should be closely related to the syllabuses of other subjects. In the course of their studies in chemistry, the children practise a variety of communication forms. Genres and activities learnt in learning Hungarian language and literature provide a good background for this, and chemistry classes provide pupils with opportunities to utilise their relevant skills. Creating oral and written texts about chemistry topics will greatly contribute to the development of pupils’ ability to express themselves. Writing reports on the findings of their experiments will develop language abilities such as accuracy, highlighting significant bits in phenomena seen. Describing – orally and in writing – of the explanation of phenomena will help pupils to learn to use chemical terminology accurately. Learning about the history of the application of chemical procedures, of the discovery of chemical elements, compounds and methods, as well as the activities of outstanding chemical scientists will enable them to see chemistry as a part of the history of universal culture. Simple calculations involved in stochiometrical equations will demonstrate the application of mathematics in natural sciences. In practising, applying and developing skills learnt in Information technology, pupils will practice basic self-education, self-information techniques. Being introduced to simpler biochemical, geochemical and meteorological phenomena will make pupils see that biological, geochemical and meteorological processes can often be explained with the help of chemistry.

With respect to environmental education, the most important task is to make pupils understand the importance of protecting natural waters, the air and the soil from chemical pollutants. When discussing relevant environmental phenomena, the children will realise that they themselves can do a lot to protect their own environment, and that in their family, school and place of living they have many opportunities to reduce environmental problems locally.

In essence, teaching chemistry in the primary school aims to provide pupils with basic chemical understanding and the skills to use this understanding routinely, whereby they will become better able to solve everyday problems with chemical aspects (e.g. foodstuffs, solvents, cleaning agents, poisons, plastics, drinking water, sewage, waste etc). During their studies in primary school, pupils will gain a deeper understanding of materials and material changes. Acquiring knowledge of the syllabus contents and after suitable skill development activities, pupils will have acquired knowledge and understanding in chemistry which is appropriate for their age and which will provide them with suitable ground for further scientific study in secondary school.

Developmental requirements
Skill in obtaining, processing and applying information
Pupils should become adept at the safe and professional use of materials and tools, as well as meticulous observation. They should practice using units of measurements covered in the syllabus, as well as their fractions and multiples in measurements and simple calculation problems.

To examine spatial relations of molecules, and also to interpret the composition of molecules, pupils should use models.

Pupils should become adept at research, at highlighting material portions, in selecting, summarising and organising data. They should be able to use lexicons, compilations of formulas and tables, as well as multimedia educational materials.

Through regular tasks and through the appreciation of independent work, pupils should grow accustomed to using popular scientific publications, lexicons, handbooks, school and settlement library and media library, as well as digital and broadcast media. Pupils should become adept at filtering scientifically sound information from the wealth of information directed at them, and also at using the media in a critical fashion.

Pupils should collect and appropriately categorise the data obtained through observation, measurements and note-taking. They should encounter the steps of systematic organisation , and see an example of how sets can be organised into a system.

Pupils should practise interpreting and using tables, charts, diagrams, graphs and drawings in order to be able to create similar representations. The transformation of verbal information into information depicted in images – and vice versa – is a great challenge for pupils. This important skill may only be efficiently enhanced in upper years if during primary school years, pupils become skilled in using elementary ways of representation.

With the teacher’s help, pupils should analyse information and findings gained though investigation, measurements and research; they should interpret the phenomena discussed, highlight correlations, make conclusions and general statements. Surprisingly soon, pupils will become able to make statements on their own on the basis of the available information. Even at this early age, children of a more inquisitive nature can be expected to be able to transcend simple reproduction and to explain and interpret natural phenomena and processes, as well as technical applications which they find interesting. These pupils need to recognise those simpler or more complex problems which need explanation, and find explanation for some of them on their own, on the basis of their existing experience, understanding and cognitive skills.

This performance can only be expected from pupils who are able to use oral and written technical terminology in an accurate, correct and precise way. Pupils should be able to express their understanding, questions, problems and opinion when creating texts. For this, they should be able to use skills learnt during the study of their mother language as a subject.

Over the last decades, environmental problems have become part of public thinking. Pupils should be familiar with the causes and consequences of global and local environmental problems. They should see that we all use and pollute our environment throughout our lives, and that therefore its condition also depends upon our lifestyle. When analysing the situation and when searching for possible solutions, they should rely on understanding gained through various scientific subjects. They should recognise environmental problems in their everyday life, and, together with their teachers and parents, try to find solutions to simpler ones.

Their personal experience gained in their family, school, wider surroundings and studies should make pupils understand that health and a healthy environment is an irreplaceable value for the individual and smaller and larger communities. They need to be familiar with environmental factors and the components of our lifestyle which might endanger these values.

Familiarity with matter

Our understanding of the structure of matter is essential in our world view. Pupils should possess an understanding of the particle nature of matter which is in accordance with their age and abstraction ability. Their experiments and studies should give them an understanding of the atomic structure of the most important inorganic material, the other important properties following from their structure, as well as the possible dangers and safe utilisation.

Of the materials found in our environment, we come into the most direct and longest contact with those we consume. Pupils should obtain an overview of the role and value of foodstuffs, of the role of nutrition in preserving health, as well as healthy eating habits.

Of unhealthy substances, nicotine and readily available psychotropic substances are the ones which directly endanger this age group. Smoking is becoming very widespread among children of 13-14 years; therefore, demonstrating the damages done by nicotine is a very important element of chemistry teaching. Teachers need to find a manner of presenting the dangers, long-term individual and social consequences of smoking which makes the pupils determine not to start smoking. Pupils should be aware of the effects of substances liable to affect them, and they must refuse consumption of these materials.

Navigation in space. Space and natural phenomena
In accordance with the level of their understanding of atomic particles, pupils should develop an understanding of the proportions within atoms, as well as an understanding of the differences in the order of magnitude of the size of chemical particles and perceivable objects.

They need to be familiar with scientific learning and the evolution of science.

By the end of their primary school studies, pupils should now that the diverse material world is made up of a single system of atomic particles. They need to understand that nature is a single system, although investigated by making through various criteria, methods and scientific disciplines. They need to be aware of the fact that scientific understanding travels a winding path to progress. The accumulated knowledge is the joint effort of the entire humankind, embodying the entire pool of experience gained by former generations, as well as the talent and efforts of scientists devoting their lives to the investigation of scientific problems. Pupils should be familiar with the most famous Hungarian and foreign scientists relevant to their knowledge in the field of chemistry. They should be aware of the fact that technological achievements require a systematic and creative application of the laws of nature.
