My younger brother was assigned a to make a quiz board project for physics class, and I believe that instead of doing what is shown on the format sheet, we could make one much more attractive and practical.

Here's my problem... I have never even touched a wire before. So, I just need a little help on the set-up, and what I should purchase. I've already done a little bit of homework about this, so lets see if it pays off.

Basically, we have 6 questions and six answers.
I think I need a momentary button next to each of the questions, that when pressed down will light up a christmas light that is next to that questions corresponding answer.
All of this should be able to fit on a 24'' x 14'' foam board.

Diagram time!

() = Button Off | (!) = Button Press
** = Light Off | *!* = Light ON

Non-Functioning
() Question # 1 Answer # 4 **
() Question # 2 Answer # 3 **
() Question # 3 Answer # 1 **
() Question # 4 Answer # 5 **
() Question # 5 Answer # 2 **

When playing the game:
(!) Question # 1 Answer # 4 **
() Question # 2 Answer # 3 **
() Question # 3 Answer # 1 *!*
() Question # 4 Answer # 5 **
() Question # 5 Answer # 2 **

Anyone think they can help a poor soul out?

So you're saying that when you press the button for question 1, the answer for question 3 lights up?

I'd say you have wired the button for question 1 up to the light for question 3.

And why are you doing his homework?

Hi and welcome to Electronics Point :)

You said 6 questions and 6 answers but your "diagrams" only have 5 of each.

So you just want a column of buttons, and a column of indicators, with the buttons wired to illuminate the indicators with some predetermined mapping?

You've answered your own question. You need:
6x "momentary" pushbuttons;
6x light bulbs in holders, or LEDs with current limiting resistors (see https://www.electronicspoint.com/threads/got-a-question-about-driving-leds.256849/ );
1x power source to suit the light bulbs or LEDs
Insulated wire

Here are some links to components on Digikey. I don't know where you are because you didn't fill that in on your profile, but if you don't buy from Digikey, at least these will give you an idea of what you can use.

Pushbuttons:

If you want to be smart you could do the mapping between questions and answers using a pluggable module, so you could use it for different sets of questions and people couldn't learn and remember which answer number corresponds to each question.
