Project ideas for a Geometry class?

Question

I'm a first-year teacher with a very rambunctious group of sophomores in a Geometry class. I've been trying to think of a good project for them to do. Something hands-on would be good. They already did tesselations (a staple of every high school geometry class) and really worked hard on them and did a good job. I'd like to do two projects per semester, but can't think of another good one. If it helps, we're working on proofs and midsegments of triangles right now - but the project doesn't have to be directly related to that.
Any ideas for something I could assign to these kids would be greatly appreciated. Thanks!

I remember we all went out side and used a shadow of a flag pole to measure the apx height.
