15 Birthday Party Themes For Kids

Planning birthday parties for my kids is one of my absolute favorite things about being a mom. I love brainstorming ideas with them, scrolling Pinterest for decorations, games, food, and party tips, and ultimately, bringing their visions to life in a way that makes them feel loved, known, and celebrated. I usually start months ahead of time and I thoroughly enjoy the process from start to finish.

But I realize that not everyone thrives in the same way, and what is life giving to me, may not be life giving to the next person. That is one of the reasons I love blogging. I get messages from moms, thanking me for putting party ideas together so that all they have to do is purchase similar items, download my free printables, and set up their child’s party without all of the legwork. It brings me so much joy to know that I am making life easier for those who do not enjoy the creative process of party planning in the same way that I do.

Over the years, I have posted at least 15 different party themes, and I thought it was time to do a blogpost compiling all of these ideas into one for parents who are not sure what theme to go with and would like to browse through all of the parties I have put together over the years. Here is a list of all of the parties on my blog so that you can have quick links to get to each of them to see if any spark interest in your child. Happy party planning!

In addition to these full party posts, I have 15 fun treats and activities that can be incorporated into some of your future parties.

I hope that this post provided some fun inspiration for your upcoming events. Leave a comment to let me know what your next party theme is going to be!


Science Experiment Party


Micah is our little scientist.  He loves all things science, so naturally, when he was about to turn 10, we began to plan the ultimate Science Experiment Birthday Party.  The vision started to take shape one afternoon when we bought a slab of dry ice for Micah to “play” with.  He literally spent over 4 hours experimenting with it.  I decided then and there that dry ice experiments would be the main event of the party.  I wanted to include a couple of other simple activities as well.  A Coke and Mentos demonstration, cornstarch and water play, and build your own edible molecules made this an unforgettable birthday party!

The decorations were quite simple, since most of our time was spent on the science activities.  I created a really fun “Happy Birthday Micah” banner using letters from the periodic table and a couple of science symbols.  My cricut came in handy for most of the homemade decorations.  I used an old toy microscope as our centerpiece and placed Micah’s plasma ball near the food area.  I used a black sharpie to draw lines and numbers on clear plastic cups to make them resemble beakers.  I lined our counter with everything needed for the party, so that it was quickly accessible to keep things moving along.

We read up on the proper safety precautions needed when handling dry ice, so we were well prepared to host a party of this kind.  In the birthday invitations, I asked that a parent be present to help supervise their own child/children and asked the kids to come dressed in long sleeves, long pants, and close toes shoes.  We provided gloves and safety goggles for each person handling the dry ice and when the kids arrived we were all ready to go. #CommissionsEarned

Water mixed with dry ice in some mason jars makes for some pretty awesome smoke, but when you add a couple of drops of dish soap, you take it to a whole new level.  What kid doesn’t like to create a giant mass of bubbles that turns to smoke when popped!?! IMG_9592IMG_1705IMG_9585

Did you know that you can blow up a balloon by placing it over a water bottle with a small chunk of dry ice inside?  But why stop there, a rubber glove pulled over a mason jar will work as well…and it’s pretty awesome to let it fill up so much that it pops off all on it’s own. IMG_1711

Time to get messy.  Cornstarch mixed with water makes for such a great hands on experience.  You can actually shape the mixture into a solid ball, open up your hand, and then watch it melt before your very eyes and turn back to liquid form.  And what kid doesn’t enjoy getting a little bit messy just for fun!?! #CommissionsEarnedIMG_1724IMG_1670

Dots candy and toothpicks make the perfect edible molecules.  Try and create real models, like carbon dioxide, or just create your own crazy molecule.  Science can be fun and tasty at the same time! IMG_1684IMG_1733IMG_1737Petrie dish anyone?   A couple of drops of food coloring, a few sprinkles, and 4 of Wilton’s black sugar pearl sprinkles turn ordinary green jello into an edible science experiment.  #CommissionsEarnedIMG_1677IMG_1662Gummy lifesaver topped marshmallow pops dipped in nerds are always a huge hit in our house.  I used Wilton’s candy melts in dark chocolate and orange to create these yummy treats.


Wilton’s candy melts are perfect for creating edible cupcake toppers.  To go along with the science theme, I created beakers, test tubes, and molecules.  Mini m&m’s completed the look.  IMG_1648IMG_1675IMG_1650

What’s a science party without test tubes?  These plastic test tubes made great party favors to send home with Micah’s friends.  Chewy Airhead Bites are the perfect size candy to fit into the tubes, but you could use a variety of different candies. #CommissionsEarnedIMG_1651
