Creativity in teaching is extremely important for the pupils' development and they need to be provided with knowledge and skills to look for new problem-solving strategies. Pupils need to be encouraged to see the usefulness of creativity and to apply it outside the classroom. The teacher's task is to guide the pupils in that process and to point out how they as individuals, a couple, or a group can have control over that process. The concepts related to climate change and care for the environment are complex, hence they need to be adapted to the cognitive abilities of pupils from 1st to 4th grade of primary school, which can be problematic, demanding, challenging, and time-consuming if teachers do not approach it creatively and if they are not sufficiently educated in that field. It is necessary to raise awareness of that problem in order to be able to contribute to the improvement of our lives, hence this research was conducted through an online questionnaire in the Republic of Croatia which aimed to examine teachers' attitudes about creativity in teaching science, especially on topics related to environmental problems. Participants shared knowledge on which topics or areas pupils are particularly interested in, which teaching strategies and methods have proven effective, and which teaching activities can be carried out outside or inside the classroom, and are related to the environment and climate change.
