Birthday Parties

Port Discovery is Open for Play!


Birthdays at Port Discovery Children's Museum 

Port Discovery Children’s Museum has temporarily suspended in-person parties as we are currently working to reimagine your child’s future birthday filled with moments of wonder! Be on the lookout for what’s to come in 2021! Please be sure to check out some fun at-home birthday ideas below!

At-Home Birthday Party Ideas & Tips!

Parties for PreSchoolers

Host a great party for your three, four, or five year old, featuring some of our favorite activities!

Ready to celebrate your little one’s birthday? Enjoy some of our favorite experiments, art projects, and shows — all easy to put together with household items and a little imagination.

Painting with Slinkys

Slinkys are a favorite with kids (and adults!), and adding paint makes the play even more fun. All you need are some sheets of paper, paints, and a few slinkys. Mix the colors together and get painting!

DIY Hoop Gliders

Upgrade your paper airplanes with hoop gliders! Decorate some paper with markers until it looks like your type of glider. Then tape it onto a straw and throw! Compete to see whose glider flies the farthest, or experiment by using different sizes for hoops and straws.

At-Home Music Time

Join Miss Cailin for music time, featuring your hands, the floor, and your singing voice! Get ready to count and clap along.

A Storytelling Opera-tunity

Miss Cailin is back with a story! Join her to learn about opera, featuring a kid-friendly performance of Romeo and Juliet. Feel free to sing along and prepare for dancing!

Outer Space Themed

3… 2… 1… blast off! Reach for the stars with a space-themed birthday party!

Take your next party out of this world with these fun activities! We’re going to travel across the galaxy, learning about the planets on the way.

How-To DIY: Rocket Building at Home!

First step to exploring the stars: takeoff in a rocketship! Try out two different models. One is made of  balloons, straws, and string, and the other needs vinegar, baking soda, and a water bottle. Both will float! 

How-To DIY STEM at Home: Crater Time!

First stop for your rocket: the moon! Learn about how meteors cause craters on the moon and other planets with this fun experiment. Make sure to have flour, cocoa powder, and plenty of space outside.

At-Home STEM Projects Courtesy of NASA

Now that you’ve landed on the moon, it’s time to make a moon habitat! Learn how astronauts live in another atmosphere. Following NASA’s instructions, create your own moon habitat. Use old newspapers, tape, and staplers, and work together!

Meals from Outer Space

No birthday is complete without a birthday treats. Try out some delicious recipes from NASA! Shape your own asteroids with homemade mashed potatoes — everyone can make their own!

While the asteroids are in the oven, learn about the moon’s phases with Oreos. NASA has a helpful PDF explaining how each phase of the moon looks just like an Oreo. A new moon is just the black sky, so make sure to eat all of the cream filling off your cookie!

Birthday Party Policies


A 50% deposit is required at time of booking and all remaining balances are due one week prior to your scheduled party.


Cancelled parties booked six weeks in advance of scheduled date will receive a 50% refund of their deposit.  Cancelled parties booked less than six weeks forfeit their full deposit.


A rescheduled party must be rebooked within one month and be held within six months of original party date. Please keep in mind that we are currently able to accommodate parties through January 2019.

Inclement Weather

If, due to inclement weather on or around the date of your reserved party, you feel the need to cancel your party, Port Discovery Children's Museum reserves the right to retain your deposit if the Museum is officially open for admission on the day of the scheduled party. In the event Port Discovery Children's Museum is officially closed, we will reschedule your party for a later date.


Decorations are not permissible due to new paint and redesign of the birthday party rooms.
