The camps are encouraging young ones to keep their minds active as well.
Max Olgmanns, 7, was among the youngsters who jumped right into their first robotics lesson at Lavner Camps in Bala Cynwyd.
"I'm basically interested in anything involving technology," Max said.
The goal, of course, is to learn to make a robot. The trick for these campers is learning how to get there.
"All I need to do to make it move. It would be kind of like an engine," said 8-year-old Taylor Levinson.
Cooking sessions were also in full swing. Chicken stir fry was on the menu for the culinary campers, but first things first. These "chefs-in-the-making" learned the safe way to chop with hoping of boosting their kitchen repertoire.
"I've cooked a little in school, occasionally at home, but this will be a fun change," said 13-year-old Alexandra Gredzinski.
Exploring and focusing on one or two specific interests is the idea in this camp.
"I think the trend you'll see nationally - some summer camp specializing in certain areas. I think traditional day camps are a lot of fun, learn skills, excel," said camp owner Justin Lavner.
Not everyone was a novice at their chosen program. Some experience tennis players were polishing their skills, hoping to play tennis in Division 1 programs.
