Merlot II
MERLOT is a curated collection of free and open online teaching, learning, and faculty development services contributed and used by an international education community. The MERLOT Collection is made up of over 40,000 materials in 19 different material type categories. Resources are geared towards college-level, but many are suitable for a high school audience. You can browse or search the learning materials in MERLOT. Every material in MERLOT indicates on the metadata record whether the material has a cost associated with its use or if the material is copyrighted
