The study of science experiments and the question of how such experiments could be integrated into a regular German lesson have led to these findings:
There is a large amount of interesting science experiments that are very easy to understand and perform and which can easily be integrated into a German curriculum.
For such an integration of experiments, certain rules and safety precautions have to be taken.
A prerequisite for successful implementation of such a project is that the materials needed can be easily obtained and in advance.
Some vocabulary (e.g., the names of the materials, simple phrases) should be pre-taught.
Learners should practice the way a researcher would proceed in experimentation, i.e.:
Links to their own observations and life situation.
Formulating a research question (e.g. W-questions, give examples)
Forming hypotheses in conversation (vocabulary must have been introduced for this, e.g. Probably..., I assume that,… It is probable, that... or very simple propositions).
Conducting an experiment in a team and making observations (taking notes, using a researcher's book).
Think tank on how to answer the research question after conducting the experiment based on findings.
Teachers must learn supportive methods (scaffolding), e.g. questioning techniques, visuals to aid the comprehension process, use of media to memorize, rehearse and consolidate thoughts, vocabulary, chunks.
