But that learning may be cut short if the camp can't raise desperately needed funding - and fast. It needs $100 per week for each camper to stay open. Much less than that has come in because many parents have been laid off and can't afford to pay. Money from other sources has dried up too.
"We had over 65 kids coming to us from different agencies, prepaid, and that didn't come through this summer. This is why we're in such financial stress," said Waller.
Waller says keeping the camp open is important because it's not just a place for kids to learn. It also keeps them occupied through the summer months and out of trouble in other places.
"Watching TV, probably doing something I'm pretty sure I'm not supposed to do," said volunteer Christian Andrews. "I get a sense of responsibility for the kids. I'm basically a mentor for them."
Now, with a weekly budget of $5,000 and dwindling support, the camp could close within days. Organizers say a flood of donations is desperately needed.
"I would want somebody to do it for my little brothers and sister, or would have done it for me, since I didn't go to summer camp," offered volunteer Qdeisha Robertson.
Fun in the Sun has a fundraiser planned for Friday. It's a fish fry from 1 p.m. to 7 p.m. at 2312 South Alston Avenue in Durham. If you can give money, click here to donate to the camp's parent organization: the Star Foundation.
