A barge is hauling metal beams through the Panama Canal. While the barge is in a closed lock in the canal, all the metal falls overboard into the water in the lock. The water in the lock falls.

I believe this is a 'density' question.
The metal beams are more dense than water. When the beams are on the barge, a volume of water equal to the weight of the beams is 'displaced' (rises) by that weight. This volume of water is greater than the volume of the metal beams (because of the difference in density between water and metal).
When the beams are in the water (at the bottom of the canal) they displace an amount of water equal to their volume which is an amount of water that is LESS than the equivalent weight of the beams.
Hope this helps. Best wishes.
P.S. This is a very interesting physics question!

The barge floats higher due to the loss of weight and the displacement of the water decreases, lowering the level.

Please see the links listed in the sourses section. They may help.
The water has to be at a certain level for the lock gate to open and let the boat out.

Gravity holds our atmosphere on top of our heads, and keeps everything below it intact/safe. Gravity pushes down on everything on Earth.
Good Luck and I hope I helped!

water falls due to gravity, which is the effect of the Earth's attraction/pull on masses.

the metal has became a lock or dam.
