Lesson plans, activities, worksheets, and STEM kits for Pre-K through 12th grade – created by educators who teach in real classrooms every day.
Great STEM teaching requires more than a textbook and a worksheet. From designing hands-on engineering challenges to scaffolding scientific inquiry for early learners, K-12 educators need practical, classroom-tested materials written by people who understand the daily realities of teaching. RelayEd connects you directly with working teachers and STEM specialists who create the resources they wish they'd had.
We're building a library of K-12 STEM resources – from lesson plans on force and motion , to hands-on activities for early learners , to full units on the engineering design process . As our educator community grows, so will the materials available here. In the meantime, explore teaching strategies on the RelayEd Blog .
The kinds of resources our K-12 educators are building for this collection.
Standards-aligned lesson plans and multi-week units covering life science, physical science, earth science, engineering, and mathematics.
Inquiry-based experiments, engineering challenges, maker projects, and guided investigations with student handouts.
Practice sheets, graphic organisers, vocabulary activities, and formative assessments ready to print and use.
Complete project guides with materials lists, step-by-step instructions, and assessment rubrics for classroom or at-home STEM exploration.
