English webs to improve children's skills

http://learnenglishkids.britishcouncil.org/en/ An excellent way to improve English through stories, games, songs and arts and crafts.
First I would present the web to the children and explain them how to use it by showing them some examples. Some of the activities could be used as reinforcement activities or simply as having fun by playing the games and listening to the stories.

 http://www.bbc.co.uk/schools/scienceclips/index_flash.shtml
A very useful web for those schools that teach science in a foreign language (English in this case). It is separated into different blocs and divided into different ages. Children learn about animals, plants and other topics by playing and answering quizzes.
I would use it in class using the projector and playing the games with some volunteers (warm-up activity). After that I would challenge the children to elaborate a project about a specific topic and use this web to get the needed information.
