Unlock hands-on STEM learning with one complete kit

The BIGRANK Science Kit is a portable, all-in-one lab designed to turn curiosity into tangible electronics experiences. Inside, 58 circuit parts and 34 circuit elements give kids flexible building blocks for creative exploration, from glowing lights to spinning fans and musical cues. The compact design encourages ongoing experimentation and repeat play, whether at home or on the go.

What you can build with one box

With a single box, kids can explore dozens of configurations and assemble items that respond to their ideas. The kit supports 520+ project possibilities, depending on how components are combined, giving room to experiment and iterate as ideas evolve into functioning demos or small inventions.

• Radar modules, fan modules, fiber optic filaments, and light bulbs spark visual and interactive results.
• Sound modules and small motors introduce cause-and-effect learning with real-time feedback.

Why this kit appeals in real life

Portable and neatly organized in a reusable storage box, the kit travels easily for family trips or weekend workshops. It’s designed to engage kids ages 8 to 12 in a safe, hands-on way, encouraging questions, careful observation, and problem solving as they tinker.

• Great for classroom warm-ups, family science nights, or independent tinkering at home.
• Helps develop critical thinking and practical electronics basics through play.

Getting started and safety

Notes for smooth setup: a few small parts require adult supervision for younger children. The kit runs on batteries—3 AAA and 3 AA—batteries are not included. A clear, supervised environment helps kids explore with confidence.

Perfect gift option

Whether for a birthday or a holiday, this BIGRANK kit blends education with play and keeps young minds engaged year-round.
