Mystery Science review
A focused K–5 curriculum for teacher-led science instruction and homeschool learning.
Reviewed by iTechGuides Editors · Editorial team · Updated Oct 2026
Mystery Science is an online science curriculum for kindergarten through fifth-grade teachers and homeschool educators. Its materials support teacher-led instruction across life, physical, Earth, and space science. The curriculum combines five-minute mini-lessons with hour-long lessons, narrated videos, activity guides, classroom timers, worksheets, assessments, suggested extensions, projects, readings, and online resources. Activities use common classroom or household materials, making the product suited to educators planning structured, standards-aligned science units.
Pricing is divided between school access and homeschool access. The Science Only plan costs $2,199 as a flat price and provides access to the Mystery Science curriculum. The Homeschool Membership costs $199 as a one-time annual purchase and includes full access to lessons and resources. School pricing may vary by school size or district and requires submitting school information. There is no free plan, so organizations and educators should evaluate the paid access model against the breadth of instruction and resources they need.
Mystery Science is primarily browser-based, with access through Mac or PC browsers including Chrome, Firefox, Safari, and Microsoft Edge; mobile viewing is also supported. Google Classroom and Google Forms integrations help teachers distribute student links, digital assignments, and assessments within a familiar workflow. The product is a strong fit for K–5 educators who want guided, multi-subject science lessons with supporting materials and digital assessment options. Educators seeking a narrowly focused lesson library, or a non-browser product, may prefer a different approach.
