Learning Objects

Natural Sciences

Dive into Wisc-Online’s rich collection of learning objects — bite-sized, interactive, and designed for real learning. These modular digital tools include animations, drag-and-drop exercises, quizzes, videos, and more. You can explore topics across STEM, arts, humanities, career skills, and beyond. Each learning object is crafted to help learners actively engage with content—reviewing, applying, self-checking—in a way that’s flexible and self-paced.

Why Wisc-Online Moved to WisTech Open

In January 2026, Wisc-Online transitioned to WisTech Open to better align with current educational standards and long-term goals. During this process, the catalog was reviewed and content that did not meet accessibility requirements or was outdated was removed. Games were also taken down, and the team is evaluating the possibility of adding them back in the future with accessibility and quality standards in mind.
