The Pacific Science Center is a great place for the kindergartner through junior high crowd. The exhibits are interesting and interactive and keeps the kids entertained. The IMAX theater is impressive, so definitely catch a movie while you're here, and the laser show is compelling as well. There's a lot to see and do here, so plan on spending the afternoon. The Seattle Center Food Court is just a short walk a way, so it's nice to take a break and return for more. Definitely one of the nicer Science Centers around the country.
