What to pack for a school weekend trip to the beach?

pack clothes for however many nights, plus an extra. I think cams, a swimsuit, t-shirts and shorts should be fine. And then a towel, sunscreen, bug spray, and water bottles should be packed, too. I think maybe if you need-goggles, and a swim cap. Also, I'm a person who always packs extra, so haha, an extra toothbrush...also, a camera, if allowed, and a cell phone should come with.
