The environmental education is a cross-cutting theme that can be implemented into every educational subject. The aim of the paper was to find out from 123 pupils of the first year of SOŠE in Trnava in the school year 2019/2020 the experience with the completed lessons of Technique at their primary school and the environmental topics they met there. The authors also examined the opinions of pupils from the completed Technique lessons at elementary school about working with implements, tools and machines, about developing their creativity by designing and producing/ manufacturing their own products. A questionnaire survey was carried out. A question to find out how they remember the environmental topics discussed in the lessons of Technique showed that 63.3% of respondents did not learn or do not remember the area of environmental topics from Technique lessons. Most of the positive answers, 12.5% of respondents, said that they remember waste sorting from environmental issues. At the end of the article, the authors pointed out the reasons why the cross-cutting themes of the environment are not effectively and visibly implemented at primary schools and also the role of teachers in improving the environmental readiness of pupils.
