The Go-Lab Initiative (sponsored by Next-Lab project) provides a Sharing and Authoring Platform for Inquiry-Based Science Education in schools. At this platform, teachers can find multiple remote and virtual online laboratories in different subject domains: Astronomy, Physics, Biology, Chemistry, Engineering, Math, Environmental Science, and others. Using the authoring tool, teachers can combine online labs with inquiry apps and other learning resources in so-called Inquiry Learning Spaces (ILSs), which are structured virtual learning environments guiding students through the inquiry process. Teachers can create ILSs supporting (almost) any lesson plan in science. Students from 6 to 18 years old benefit from innovative and exciting learning activities and acquire deeper knowledge and understanding of scientific phenomena.
