Cells Genetics 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. Cells Genetics STEM Activities for Beginners answers with 50 hands-on missions for Grades 6–8 that build cell biology and genetics one idea at a time. As the book puts it: “Model, Compare, Explain Like a Cell Biologist.”

For curious middle-schoolers

What is inside

• 50 two-page STEM missions for Grades 6–8 (ages 11–13)
• 7 sections, from Cells & Cell Theory to Variation, Biotech & Design
• Look & STEM Idea and Try & Draw pages with a mission goal, time, difficulty and materials list
• Key cell biology and genetics words: Cell, Organelle, Membrane, Mitosis, DNA and Heredity
• 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: Cells & Cell Theory (8 missions, from The Discovery of Cells to Design a Cell Theory Investigation), Inside the Cell (7 missions, from Meet the Organelles to Design a Cell Comparison Study), Membranes & Transport (7 missions, from The Cell Membrane Gatekeeper to Plan a Transport Investigation), Cell Division & Growth (7 missions, from Why Cells Divide to Investigate Yeast Fermentation), DNA & Genes (7 missions, from The Shape of DNA to Design a Genetic Code Message), Heredity & Genetics (7 missions, from Dominant and Recessive Traits to Design a Heredity Prediction) and Variation, Biotech & Design (7 missions, from Mutations: Changes in the Code to Present Your Genetics 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 cell biology and genetics 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.
