27 STEM & science kit references
Filter by the scientific idea, by age-band certainty, or by whether product imagery exists. Every reference has a stable code — use it in your inquiry so we quote the correct variant. Standard production is 3-4 weeks.

Introduces buoyancy, propulsion and radio control through a buildable submarine.
Explores image formation and lens behaviour through a retro camera build.
Hands-on refraction, reflection and colour with optical blocks.
Introduces electrical signalling and Morse-style communication.
Builds a simple refracting telescope to explain lenses and magnification.
Compares solar power and radio control in one buildable vehicle.

About prices, photos and lead time. Where a CNY figure appears in a product's detail page it is the domestic 1688 source-listing reference price — not an export quotation. Imagery is labelled by type: supplier photograph, unretouched workshop photograph, or 3D render. Cards with no image show a labelled schematic, so you never mistake an illustration for the product. Factory SKUs, dimensions, age bands and packaging data appear only where a supplier spec sheet states them; everything else is marked “To confirm”. Standard production is 3-4 weeks after a confirmed order; MOQ and FOB/EXW pricing are confirmed per quotation.
