The students from the eight grade of the Primary School No 1 in Gdynia chose the project "Chemistry and Art". It was covered in 12 lessons during 6 weeks, combining two 45-minute lessons each week. 18 students took part in the project. During the first session the students got acquainted with the work methods, split into three groups and answered the preliminary questionnaire. During the second session the students received the following pigments by themselves: blue - Prussian blue (Fe4[Fe(CN)6]3). green - malachite (CuCO3Cu(OH)2), white - barium sulphate(VI) (BaSO4) or titanium(IV)oxide (TiO2), red - iron(III) oxide (Fe2O3) or red lead (Pb3O4), yellow - lead(II) chromate(VI) (PbCrO4). In the third and fourth sessions they made the following paints from the previously received pigments: water-colours (group 1), oil-paints (group 2), and tempera (group 3), and prepared appropriate undercoats for the paints. In the fifth session each group used the paints to paint whatever they desired. At the same time the students widened their knowledge of naturally available pigments, chemical and physical properties of the undercoats, nature of light and colours, history of painting and well known painters who used water-colours, oil-paimts and tempera. The students also conducted interviews with painters and visited an art gallery. During the sixth session they summarized the results in each group, shared information about the methods of preparation of the various kind of paint and filled in the questionnaire. The students' paintings were also exhibited.

In the paper the system of chemistry studies in Germany is precisely described. The future chemistry teachers often study a second, related subject; in their education the problems of environment protection are of a great importance.
Przedstawiono zastosowanie polistyrenowych kuwet do wykonania w skali półmikro prostych doświadczeń chemicznych, jak wywiązywanie wodom i chlom lub elektroliza wody. Zaletą postępowania jest łatwa obsluga i zużycie malych ilości odczynników. Opisana technika może być stosowana zarówno w szkołach podstawowych i średnich, jak również w wyższych uczelniach.

The application of polystyrene cuvettes for simple chemical semi micro experiments is presented, for example water electrolysis or hydro gen and chlorine evolution. The method is advantageous for its easy attendance and small quantities of chemicals used. The procedure presented may be applied so in elementary and secondary schools as well as at universities.
