STEM Sims review
A browser-based library of virtual labs, lessons, and teacher tools across grade bands.
Reviewed by iTechGuides Editors · Editorial team · Updated Oct 2026
STEM Sims brings virtual laboratory experiments and engineering-design simulations into a browser-based platform for students in grades 3–12 and AP. Its grade-banded labs, lessons, methods, assessments, video walkthroughs, and teacher guides suit schools and homeschool families looking for structured STEM activities. Teacher tools include class and student management, progress tracking, and assignment grading, while standards-based search supports alignment to NGSS and state standards.
The content library is the central draw: STEM Sims lists more than 350 interactive laboratory and engineering-design simulations, with virtual labs organized for grades 3–5, 6–8, 9–12, and AP. That breadth is paired with lessons and assessments rather than simulations alone, and teacher guides and video walkthroughs can help frame activities. The platform also supports standards-based searching, which may help educators connect lab work to their curriculum. Buyers seeking a broad collection across multiple grade bands may find this a closer fit than a tool focused on a single subject or activity type.
According to the published plans, Family includes access to all virtual labs, 2,000+ lessons, teacher guides for all labs, and class management. Family Plus 3-5 adds grades 3–5 textbooks with video lessons and assignments integrated with curriculum. There is no free plan, so families and schools should weigh the paid subscription against their needs; the Plus plan's added curriculum materials are specifically for grades 3–5. Google, Canvas, Clever, and Schoology login or integration options support classroom workflows, and the product is web-based. STEM Sims is best suited to buyers who want grade-banded simulation content with teacher management; those seeking a free option or curriculum additions across other grade bands should consider alternatives.
