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.
