This material is part of a large collection of activities that cover all the Catalan curriculum of social and experimental sciences for primary school. The project, created by Joan Verdaguer i Andrès, has been carried out thanks to a sabbatical year granted by the Catalan Ministry of Education (DOGC 3926 - 16/07/03).

The first set of activities, addressed to pupils 6-7 years old, has 14 units:

• The house
• The passing time
• The autumn
• The locality
• The winter
• The work
• The spring
• The materials
• The water
• The plants
• The animals
• The summer

The material is complemented with the activities on natural sciences 8, natural sciences 9, natural sciences 10, natural sciences 11, social sciences 8, social sciences 9, social sciences 10 and social sciences 11.
