For 12 kids, most science parties cost $261 to $388. A typical one is about $353. Plan on about an hour. Most take groups of up to 25 kids. Almost all include a host who runs the party. None include food, so ask before you order pizza.

Science parties mix hands-on experiments with a bit of showmanship. They are a good fit for curious kids around 5 to 10.

Ask what the kids get to take home, and whether the experiments are messy enough to need old clothes.
