Why is the sea salty?
Why is the sea salty? Grade 1 was looking for the answer to this question – as a part of the Cambridge Primary Science class. We began by analyzing illustrations and searching for information in our textbooks (reading in English practice). Then we went to practical activities and made experiments with various substances to find out which of them dissolve in water and which do not (discussing the conclusions – speaking in English practice). At the end, we summarized the knowledge gained during the class by completing the observation sheets in our activity books (writing in English). In this way, during one class we developed skills not only in the field of science, but also communication in a foreign language!
