Environmental Systems STEM Activities for Beginners – 50 Hands-On Missions for Grades 6–8

Middle school is when students start asking why and how do we know. Environmental Systems STEM Activities for Beginners answers with 50 hands-on missions for Grades 6–8 that build environmental science one idea at a time. As the book puts it: “Observe, Model, Protect Like an Environmental Scientist.”

For curious middle-schoolers

What is inside

• 50 two-page STEM missions for Grades 6–8 (ages 11–13)
• 7 sections, from Earth’s Spheres & Systems to Conservation & Systems Design
• Look & STEM Idea and Try & Draw pages with a mission goal, time, difficulty and materials list
• Key environmental science words: System, Cycle, Ecosystem, Watershed, Pollution and Biodiversity
• For Grown-Ups notes and a Certificate of Discovery
• Printable 124-page PDF — Level D “Innovators” of the Mathfa STEM series

How the sections are organized

The book moves through seven sections: Earth’s Spheres & Systems (8 missions, from Mapping Earth’s Four Spheres to Plan a Systems Investigation), Biogeochemical Cycles (7 missions, from Modeling the Water Cycle to Compare the Three Cycles), Ecosystems & Energy Flow (7 missions, from Producers, Consumers, Decomposers to Design an Ecosystem Study), Watersheds & Water Quality (7 missions, from Modeling a Watershed to Protect a Watershed), Soil, Air & Pollution (7 missions, from What Soil Is Made Of to Design a Clean-Air Solution), Biodiversity & Human Impact (7 missions, from Sampling Biodiversity to Analyze Human Impact Data) and Conservation & Systems Design (7 missions, from Reduce, Reuse, Recycle to Present Your Environmental Study). Every section opens with a mission plan, and the book ends with For Grown-Ups notes and a Certificate of Discovery for finishing all 50 missions.

Who it helps

Designed for students aged 11–13. It also works for homeschool families, middle-school teachers planning STEM units, tutors, and clubs — anyone who wants structured environmental science projects with clear goals.

How to study with it

Choose a regular STEM time — one mission per session works well. Read, predict, then build, measure or model. Record results on the Try & Draw page and discuss the evidence. When a section is complete, try its design challenge before moving on to the next.
