Gear Train Board Kit – Four Colour Gears on a Pegboard, Beginner Gears STEM Set
Mount four colourful gears on the pegboard, turn the first one and follow the motion: speed and direction change at each gear.
Designed by Mematrix Lab
Description
A first look at gears
This simple kit is a pegboard with four gears of different sizes. Push the gears onto the pegs so their teeth mesh, turn the first one and watch the motion pass along the chain. Count the turns of each gear, change their order and see how size changes speed and direction.
Science it demonstrates
- Meshing gears turn in opposite directions
- Gear ratios: small gears turn faster than big ones
- Idler gears: changing direction without changing speed
- Counting and comparing turns
What you'll do
- Push the gears onto the pegboard
- Turn the first gear and follow the motion

Shipping
Standard shipping: $9.00 for the first item, +$1.80 for each additional item. Free shipping on orders over $260.
We ship worldwide, by default with economical international post (UPU / China Post small packet) to keep shipping costs low. Orders are usually handed to the carrier within 2–5 business days, and economical international post then takes about 10–30 business days to arrive; these are estimates, not guarantees. Delivery time depends on the destination and on postal and customs handling. If you need your order by a certain date, email us before ordering: faster shipping can be arranged, with the extra cost charged at the carrier's actual rate. Items that contain batteries or magnets are marked on their product page and ship by a special carrier line; some countries and regions cannot be reached by that line, and if yours is one of them we refund the order in full.
Customs & duties
Import duties, taxes and customs requirements depend on the destination country, the shipping route and the local customs office, so we cannot say in advance whether any will apply to your parcel. Customs may hold a parcel, ask for more information, or ask for duties or taxes to be paid, even when the declared value is correct. If you have a question about your country, email us before ordering.
