Denali for Kids: Online Adventure is an excellent science and technology design model for elementary education preservice teachers. This site is informative, visual, and well organized. The Denali for Kids site models for preservice teachers the components to develop a successful activity (e.g., introduction information; interaction; online resources). Using this model's format preservice teachers could extend this design to other projects with science and technology for elementary students (e.g., Space Travels; Scientific Discoveries).
It is easy to move throughout the site and find information.
