So, what exactly do you do in the hands-on part of this event?

The rules offer some examples (like the bright light bulb task). Expect to have to build some sort of circuit and take measurements from it or a prepared one. Building materials could be as simple as snap circuits and go up in sophistication depending on what the supervisor has available.
Re: magnets, be ready for some simple magnet experiments, if anything at all.

Cool, thanks!

Does the current (amps) change or vary in a parallel circuit? I know it stays the same in a series circuit but my coach said that it can change in a parallel circuit.

It doesn't "change". But the current through each resistor is different in a parallel configuration.

Thanks. Trying to wrap my head around it, does voltage split evenly in a parallel circuit with two paths?

The voltage would be the same across both branches, but the current would split relative to the resistance of each branch. If they had the same resistance, then the current would split evenly.

If you're struggling with it conceptually, think in terms of the water pipe analogy. I find that helps me make sense of what physically is going on with what iwonder said above.

That works too, all the comparisons are on the wiki if you need.

No, I get it thanks. I just find it easier asking on the forum than my teachers or looking it up
