Finally, summer has come! This DVD explains in a way suitable for children why summer comes, how life develops in nature and why we humans love this season so much. In short chapters, children learn why daylight hours are longer and how a thunderstorm builds up. The behaviour of animals and their young as well as changes in the flora are explained in a way appropriate for children. Rules for the right behaviour in the sun, in the water and during a thunderstorm are explained just like the dangers of a tick bite or wasp sting and the right reaction in such a situation. Besides didactic-methodical suggestions, the accompanying material also includes various games, songs, experiments, tips and suggestions providing an incentive to work on a topic, which is virtually a compulsory annual subject, from different points of view and holistically and to discover it from a new angle.
