Parents’ Night Out

Pacific Science Center holds monthly Parents’ Night Out events all year round for kids in grades K-5. Recently we have expanded our Parents’ Night Out program and in addition to our evening events, we are proud to offer Parents’ DAY out and School’s Out events both at the Science Center in Seattle and at Mercer Slough Environmental Education Center in Bellevue. For questions, call (206) 443-2925.

Transfers & Cancellations: There is a $10 fee per child for transfers to another date. There are no refunds.

For all events beginning in October 2016, participants must register for a new account and complete a new medical form to ensure that our records are up to date. You only have to fill out this form once per child per year.

Participants will be supervised in age groups by our outstanding and experienced staff all evening.

November 19: Lunar Lunacy
Power your engines, set your target, and prepare for lift off! It’s time to travel to the moon! Discover how much you weigh in space, simulate the feeling of walking on the moon’s surface, and design an air-powered rocket to take-home. Visit our planetarium to get a close-up look at the moon and end the night snacking on liquid nitrogen ice cream!

December 17 (DAY OUT): Short Circuit
Prepare to be shocked as we explore the world of electricity. Experiment with a variety of circuits, design a greeting card that uses LED lights, and watch your hair raise with a Van de Graaff generator. Snack on a frozen treat using Liquid Nitrogen and explore The International Exhibition of Sherlock Holmes before this electrifying evening ends!

  • 10:30 a.m. – 4 p.m.
  • $55, or $45 for Members

Parents’ DAY Out at Mercer Slough

While parents spend an entire Saturday out, kids spend the day at Mercer Slough Environmental Education Center getting hands-on with nature science!


  • 10:30 a.m. – 4 p.m.
  • $55, or $45 for Members

October 29: Creepy Crawlies
Look under a fallen log to find all the creepy, crawly, creatures that make the forest their home. Search for centipedes, dig for worms, and follow the slug-slime trail. Study the difference between insects and other arthropods and then wiggle like a worm and slide like a snail. Interesting invertebrates will be the bee’s knees today!

December 3: Water Water Everywhere
Earth might not be the only planet in the universe with water, but its the most important to us! Explore water in all its forms during your water filled day. Watch water flow in pipes and gutters, paint pictures of clouds, and look for life in the pond. It will probably be raining, so put on those rain boots and dance the water cycle boogie.

School’s Out Programs at Mercer Slough

When school is out for kids in Bellevue and Seattle school districts, Mercer Slough has you covered! We will spend the day exploring environmental science on your child’s day off from school.


  • 8 a.m. – 4 p.m.
  • $85, or $75 for Members

Thursday, November 10: All Things Big and Small
Teeny-tiny or gargantuan, minuscule or massive. Our world is made of big and small things. Get out your microscopes and binoculars to look at tiny fungus and towering trees. Practice measuring height and weight as you decide if a whale, a tree or a school bus is the biggest. Challenge your friends to find the largest leaf and the tiniest pebble in your exploration of all things big and small.

Friday, November 11: Take a Hike!
Get ready to take a hike around the Mercer Slough Nature Park. Gather your 10 essentials, put together a first aid kit, and follow your map and compass. Practice Leave No Trace rules as you complete scavenger hunts and play games in the field. Eat a healthy hiking snack on your journey, and then see if you can follow the treasure map to the surprise at the end. This day will be a trip!
