Rockin’ Geology Party

I’ve got a seven-year old on my hands, people! How did this happen? I’m far too young to have such a big kid already, right. Right?

Alas, ’tis true. And right now my girl loves all things geological. As her current hobby of choice, rock collecting naturally lent itself to rock-sharing and hands-on exploration at her birthday party. With actually rock specimens to study as well as fun rock-themed activities, the kids had a great time learning and celebrating the birthday girl.

I started with cute (and free) rock and mineral images from this source  and built her invitations and all the paper goods from there. Let me be honest with you, I am no pro when it comes to swanky artistic software. All my stuff is created in good, old-fashioned Microsoft word. But I love the way the invites and info cards all turned out.



Next, I created image cards to build a pin board. The pin board served as my backdrop to all of the amazing rock specimens my fabulous neighbor, Mary, lent us. It pays to live across the street from a geologist!

And the rock specimens really were amazing. I had a serious case of geological envy. Kinda wanted them to stay…permanently.

Snacks were deceptively easy. I always fret over this one. Keeping it real; I’m not a big fan of party snacks. While I love to eat them, trying to find a cute way to tie them into your party is usually a bit much for me. But I came across this awesome lesson plan on making geological soil strata and decided to adjust it to meet my needs. I created a “Soil Strata Snack” and the kids went in a circle, filling a clear cup with snacks that represented the layers of the earth/soil. It was great in that all I had to do was empty stuff into bowls and the kids got to “make” their own snack. That’s a win right there on my part, people!

Then we had the kids hit up stations. This was the fun part (outside of decorating…y’all know I love to decorate). We had a rock exploration station where kids got to look at and handle different rock specimens.



I made reference cards and mini field note journals where they could write down and draw their observations.



And a rock dig area. I bought a large bag of tiny tumbled rocks, spray painted some larger rocks into “gold nuggets” and let the kids go to town trying to find them all in our sand pit. This was a big “time” hit in that the kids spent quite a bit of time here. I actually plan on doing this again with the girls, just to give them something to do outside.

There was a “Pet Rock” station, where garden rocks were transformed into best friends.

And the coolest station; the Radioactive Station. My wonderful neighbor/geologist, Mary, brought over special rocks that glow under a black light. We turned one of our coat closets into the radioactive room and the kids went in four at a time to see them.



Another big hit at the party was the cake. I made an amethyst geode cake. I looked like a baking goddess.

I’m a fraud.

Yes, I baked and decorated the cake, but it doesn’t get much easier than a bundt cake made from boxed funfetti cake mix and dyed purple, butter cream frosting dyed gray, and purple rock crystal candy. It does, however, look much harder. Again, a win in my opinion.



All in all, the birthday girl had a “rockin” good time (sorry, I couldn’t skip a pun opportunity) and her friends enjoyed celebrating with her.

And I enjoyed watching my baby girl get just a bit bigger…but not too big. I’m not ready for that.

      Thanks, Kate! I made the cards with manila card stock. I found the free images at this site,, and printed them out. I also used a rounded corner card punch for the edges, but a glass edge, pencil an scissors will do just as good of a job. Hope that helps!

    Hi Roxanne, found this page while searching for ideas for my son’s 7th birthday party. What is it about 7 year olds and rocks? Looks like you threw a fabulous party! Any chance you remember where the soil stratification graphic came from? It’s wonderfully compelling and simple for the 7 year old set. Thank you!

    Hi Roxanne – where did you get the rock crystal from? I am having trouble finding big crystals that arent on a stick or string. Thanks!

      Hi Kim!
      If you’re in Sacramento, the rock candy on string can be found at Candy Heaven. Otherwise, if you look up rock candy on string on Amazon you’ll find a ton of color options that will do!
