Fun Science Activities for Kids’ Parties

Do you have a science loving kiddo? Here are some great ideas and tips for the STEM loving kids. These are great for rainy day activities or things to keep a group busy at a party.

JP has always been a math and science kid. When he was younger we subscribed to Green Kid Krafts. It was a fun monthly box that came with experiments and projects. One month I happened to catch a great photo of his reaction to an experiment. I shared it on Instagram and tagged them. They reposted it to their Instagram and the picture made it on the back of a direction booklet. How fun!

STEM Party

In years past, we’d had several parties at local places and for this one we stayed home. One of the good things about a summer birthday is that the weather should be OK to be outside. I’ve avoided a lot of kids at the house until this party because of the pool. I just didn’t want the responsibility. By this time, I felt a little more comfortable with having a party at the house. By age 9, most kids are comfortable with water.

We had a set time for the ‘kids’ portion of the party. This is when we did a couple of projects and then they had a little time to swim. After all of the school and neighborhood kids were gone, we had a smaller amount family and friends stay. This part of the day was more relaxed.

Wigglebot

One of the projects we did was to build a Wigglebot. It was cute and they were all amazed at how it worked. The kids got to build and put together the motor and battery pack. It is a great way to start learning robotics.

The linked tutorial is great! Our kids were around the ages of 7-11. They did need some help with the fine motor of taping and some assembly. It’s helpful to have a few adults around if you are doing it as a large group.

To prep for this I made little bags for each person that included all of the supplies. This worked well so you aren’t spending time handing out supplies.

Elephant Toothpaste

The next project we did can be messy. We made Elephant Toothpaste. To prep for this I purchased 2 sizes of plastic condiment/jello shot type of containers. I collected empty water bottles and pre-filled them with the peroxide. The other supplies went into the little containers. Everything was pre-sorted for each kid in a bag on the trays. This doesn’t explode but I still had the kids jump back when they mixed everything. It oozes out and they thought it was so cool.

Party Details

After the experiments it was time for cake. The cake was from Creative Cakes (our usual). JP is very interested in Albert Einstein. I went with the generic ‘science’ theme and had them leave a spot for me to add the bobble head.

Of course I had fun with the theme and decorations. For snack items, I put jello in petri dish containers. I also filled test tubes and plastic light bulbs with trail mix and M&M’s. The dipped pretzels are always a hit and so easy to match the colors of your party.

For the other decor items I created the large background using my Cricut. It’s much larger than it can cut so in Design Space I sliced it into pieces small enough to cut. Once the pieces were cut I assembled it back together on the backdrop. The beakers were filled with water beads.

For the favor bags I included items needed for the projects as well as some fun things:

Safety glasses
Mini magnifying glasses
Candy
Their completed Wigglebot

Overall the party was a success. To recap, kids under 11 will likely need help with the Wigglebot. Extra adult hands will be a big help, especially if you have a group of kids.
