We have combined the children’s interest in making movies with their interest in biology. This is our second movie in our series of biology themes they have chosen. They have made the movie on their own. As a parent, I have only contributed with the advise on ideas and helped with the planning of their time spend on the project. The project didn’t really happen, until we put the project on our weekly schedule. They had to have a set time to work on it. Like an author, sometimes needs to set himself a set time where he works on a book. Then things started to happen.
