Base Plates for science experiment

davery

I am a noob here and helping my daughter with her science project. She is a Lego fan and wants to use them in her project. She wants to demonstrate that a bridge with an arch design is stronger than a single span bridge. We have enough legos, but need some base plates that can be the top, or road, of the bridge. That would mean the bricks need to attach from the bottom. These could be about any size around 12 x 24 or so. Any ideas?

You want plates. 16x16 are common. But you could use smaller ones in two layers, overlapping them.

Ideas on "what" to buy? or "where" to buy?

Sounds like 16x16 plates are best as CCC says. The NinjaGo game is the best set to get these from as there are 4 in a relatively inexpensive set. (BTW I noticed it was 50% off in the UK Brand Store I visited Saturday.)

Or check out BrickLink; probably cheaper.

If 16 is too wide and you need 12-wide max, you'll need to make a road out of 6x12 plates.
