The Teylers Museum in Haarlem is a small science and art museum with several educational programs for schools, ranging from primary to tertiary.
An example of how science and evolution can be introduced is the current multi- disciplinary program for grades 6, 7 and 8 primary school (10 -12 years) called "birds xxl"
based on Audubon's "Birds of America". The museum also has a model of an archaeopterix to demonstrate how birds evolved from reptiles. By comparing the characteristics of birds and reptiles, evolution can be taught in way that children can easily grasp.
I also visited this museum when I was about 10 years old and many times afterwards. My love for science was born here.
