This study aims to investigate how science textbooks and a digital tool from NTA presents the space for children in primary school. NTA stands for science and technology for everyone, it is a school development program in the subject of science, technology and mathematics. This study will also investigate how frame factors can affect the use of digital tools and science textbooks in the classroom. The following questions will be asked to answer the aim of this study:

• How is the earth´s, the sun´s and the moon´s relationship to each other presented in NTA´s digital tool and in science textbooks for children in primary school?
• How can time and knowledge as frame factors affect the use of digital tools in comparison with science textbooks in the classroom?

To analyze the empirical material, the theory Ammert´s uses to analyze textbooks will be used. The content will be analyzed by categorizing it as established, explaining and reflecting/analyzing representation forms. To analyze the pictures in the textbooks and the digital tool Wallin Wictorin´s theory about pictures in textbooks will be used.

The result of the study showed that the most used representation form of the textbooks was the established one, sometimes the explaining and the reflecting/analyzing representation form was used, but for the most part it was the established one. The result also showed that the digital tool often used the established representation form in the text they had, but the assignments had the reflecting/analyzing representation form for the most part.
