Are there any simple "experiments" that can be done in a high school science lab that could demonstrate some sort of basic principals of wormholes or spacetime? Or sort of proving how long something would take to get through a wormhole or why you wouldn't be able to travel through them etc.

My favorite explanation of something similar to a wormhole is this, from Madeline L'Engle's A Wrinkle in Time
There's a bit more after this on dimensions, but it doesn't completely explain the issue (plus it uses some slightly wrong physics--it is, after all, a children's book)
You can do this explanation with a string. Then show them that a string (one-dimensional) had to be bent into a two-dimensional loopy thing.
Then, do the same thing with a piece of paper. Here, a 2D paper is bent into a 3D thing.
Now try to explain how this is possible in the real world--bending of 3D space into 4D spacetime in a loopy manner.
It would help if you explained the standard rock-in-a-rubber-sheet analogy of general relativity at first. Of course, I've seen this particular analogy lead to misconceptions/confusions frequently. But there's no way that I know of to explain it correctly without confusing the lot of them.
