learnXdesign was spearheaded by the New York City Hall of Science (NYSCI) in collaboration with six science museums in the United States and Canada. Together, the group has created an extensive, yet easily navigable, database of science activities for youth of all ages. Designed especially for informal settings, such as after school programs, libraries, museums, and youth centers, users can search for activities by subject, age level, or the time duration of the project. Almost all projects can be completed in under an hour and many can be completed in under 30 minutes, making learnXdesign an especially valuable resource for museum educators and those who coordinate drop-in youth programming. Best of all, each activity is accompanied by a video of science educators demonstrating the activity and explaining how they incorporated the activity into their own programs.
