Edheads offers online simulations containing content from middle school to advanced levels. Students begin by choosing from 17 activities in a drop-down menu. There's a significant audio component, though captions are provided. It's recommended that students have access to headphones. All simulations have coordinating worksheets and assessments; some are optional, while others are more necessary.
Activities vary in design and length, but each starts with an introduction and is chunked into segments. The scenarios place students in content-related professional roles, such as surgeons or engineers. A few topics are geared toward younger students (machines and weather), but most are for advanced high school students, especially in the life and medical sciences.
