4m 00-03275 4M Potato Clock DIY Green Science Kit – Build a Functional Vegetable‑Powered Clock with Crocodile Clip Leads, Copper/Zinc Electrodes, Mini Clock Motor & Illustrated STEM Guide for Ages 8+ | Mod 00-03275 l

Introduce young learners aged 8 and up to green energy through the 4M Potato Clock DIY Green Science Kit. This interactive STEM project empowers children to transform everyday produce—potatoes, lemons or apples—into functional electricity sources strong enough to power a mini clock. The kit includes a clock face module, copper and zinc electrodes, crocodile clips, and a clean activity sheet that guides kids through building parallel and series cell configurations. By exploring how different produce types generate voltage, children observe electrochemical reactions, circuit flow and the basics of voltage potential. This project promotes scientific reasoning and fine motor coordination while encouraging environmental themes. It’s mess-minimal, reusable and perfect for practical STEM discovery at home or in the classroom. Packaged and branded by 4M’s Green Science range, this kit blends curriculum-aligned learning with hands-on chemistry in a compact, safe and repeatable format. Kids witness bioelectric power—from earth to clock—in one empowering experience.

• Build a unique vegetable-powered clock using potato or lemon cells—kids connect electrodes, clip crocodile leads, insert electrodes into produce and activate a real clock motor powered by chemistry and creativity from food‑based energy.
• Complete kit includes mini clock head, copper and zinc electrodes, crocodile clip leads and activity sheet—everything needed for hands-on fun exploring electricity generation from potatoes or other acidic foods in a clean, educational project.
• Encourages real-world science learning—children aged 8+ learn about electrochemical cells, voltage potential, ionic conduction and circuit design by experimenting with different produce and electrode placement to maximize clock runtime.
• Supports environmental awareness and green STEM learning—using renewable bioenergy from root vegetables or fruits, kids explore sustainable power sources and gain insight into simple energy alternatives and chemistry essentials.
• Perfect STEM gift or classroom experiment—packaged for easy setup and reuse, ideal for birthday gifts, science fairs or family science time with instant visual payoff and multi-device exploration potential.
• From trusted 4M Green Science curriculum—safe, classroom-tested components backed by clear instructions that combine chemistry, engineering and hands-on creativity into a memorable, educational experience.
