Alright in bio we did a lab where an old candle was placed in a finger bowl. The finger bowl was filled with 150 ml of water so the water went up to 1/2 of the candle. You light the candle and cover the candle with a beaker. In about 10 seconds, the candle goes out. Why did that happen?

Yes, I agree that the candle used up all the oxygen available under the beaker.
I suspect that the reason water was in the bowl was to be sure that no air leaked under the bottom edge of the beaker.
The process of burning is called oxidation because it uses oxygen. As soon as the oxygen is used up, the burning stops. That's why firefighters sometimes spray foam over whatever is burning. The foam cuts off the air supply.

the candle flame didn't have enough oxygen to continue. For example: if you cover a candle with a container, the candle flame will go out. Thats my guess
