1. Food Decorations

At a science-themed kids party, the food can be just as fun and creative as the decorations. Here are five cool food ideas to delight young partygoers and tie into the scientific theme. For more ideas, check out the Blog posts in the Science Party Food Ideas.


1.  "Edible DNA"

          - Creating a delicious twist with licorice and marshmallows to represent the structure of DNA molecules. I actually do this at school to

            educate the student on the components of DNA and their function in hereditary. For those teachers out there, check out the DNA A3

            posters that I use with genetic cards. (Teachers are always looking for new and creative material to engage kids...!)



2. Galaxy Popcorn

           - Mix popcorn with colorful edible glitter and star-shaped sprinkles for a cosmic snack.

           - The edible glitter is from cake decoration providers.


3.  Fruit Skewer Rockets

            -Assembling fruit chunks on skewers to resemble colourful rocket ships ready to blast off.


4.  Jelly Planet Slices

            - Round cookie cutters to shape colourful jelly into planet-like discs.


5. Volcano Cupcakes

              - Red frosting lava spilling over chocolate cupcakes, creating a delicious eruption of flavour.


These creative food ideas are sure to be a hit at any science kids party, adding an extra element of fun to the celebration. You of course can add so much flare with using alliteration for names, little signs etc as shown in the few examples below.

If you would like MORE examples, checkout the gallery and the Blog Posts on decoration ideas. I mean, let's face it: it is SO much fun getting your brain cells and creative mind into making these as well.  Admit it.

When it comes to science-themed cakes for kids' parties, the possibilities for creativity are truly endless. From beakers bubbling with colorful liquids to solar system cakes complete with edible planets, there are so many fun and imaginative ideas to explore. Here are some quick ideas:

      1. Microscope shape cake

                                     - A flat cake can be made easily at home and decorated to look like a microscope. Placed around the 

                                      cake can be plastic petri dishes filled with jelly and sour worms. This provides a visual for 

                                       microbiological plates.

      2. Volcano Cake:

                                    - This classic cake has SO many options. Over the years I have seen the smash cakes with lollies inside 

                                       being modified  to include a container in the middle. The container can then be filled with water and

                                        dry ice to provide the smoke OR  the classic bicarb and vinegar (although this is a little messy). The

                                        birthday child them smashes the cake after the  volcano has exploded!

      3. Periodic Table Cake:

                                     - Featuring elements spelled out in frosting. The elements can be created with the symbol elements

                                       spelling out the birthday child's name.

     4. Fossil 'dig' Cake:

                                      - When cut, little fossils inside the cake can be found. It can be decorated with mini dinosaurs on the

                                         top of the cake.

     5. A Willy Wonka Cake

                                      - You can mix and match your creative ideas. My science parties have been used along with other

                                       themes such as Harry Potter, Pokemon, Dinosaurs and Willy Wonka to name a few.  The cake below was

                                       an amazing creation that could be used in a Wonka Party. It was used in a recent party around the

                                       theme os 'S' and Science was part of that theme.




These creative science-themed cake ideas are sure to impress young party guests and make a memorable centrepiece for any celebration. Let your imagination run wild and bring a touch of scientific wonder to the dessert table with these exciting and visually stunning cake designs.

3. Science Decor

In addition to getting a professional host such as myself The Crazy Scientist, you can enhance the party location by creating a laboratory atmosphere with test tube flower vases, beaker centrepieces filled with colourful liquids, and bubbling dry ice experiments. Hang a solar system mobile from the ceiling, scatter glow-in-the-dark stars across the walls, and use black lights to make fluorescent decorations pop. Incorporate elements like periodic table tablecloths, atom-inspired balloons, and constellation banners to set the stage for a truly immersive experience.


Other decorative aspects you might light to include are:


1. Tablecloth designs


2. Cups and creative water bottle labels


3. Balloons

        - These can be printed, professional made or (if you are crafty) made

           yourself. Here you can see how a parent recently made a great

            bubbling beaker with balloons. So cool.


4. Entrance decorations (signs, stickers, spider webs, radiation elements


Consider adding a DIY slime station, a mad scientist photo booth, or a mini rocket ship prop for interactive fun. With these science decor ideas, you can transform any space into a whimsical and educational playground that sparks curiosity and excitement in party guests of all ages.

Tablecloths, stickers, cups etc

4. Science Dress-ups

Dressing up for a kids' science party opens up a world of exciting possibilities to ignite young imaginations and foster a sense of wonder.


Encourage party attendees to come dressed as their favourite scientist, astronaut, or even as a mad scientist with lab coats, safety goggles, and funky hair accessories. For a space-themed party, guests can don astronaut suits, futuristic space gear, or alien costumes to explore the outer reaches of the universe.


Alternatively, embrace a STEM theme with attire inspired by robots, engineers, or inventors, complete with gear belts, tool kits, and tech gadgets. To add a touch of magic, consider fairy or wizard costumes with a scientific twist, such as wands that light up or spell books filled with experiments.


By encouraging creative and imaginative dress-up ideas, kids can fully immerse themselves in the scientific theme of the party and embark on a thrilling journey of discovery and fun.

In my parties as The Crazy Scientist, I dress up with a multi-coloured tie-dyed lab coat. This not only makes the atmosphere fun but also gives me opportunities to talk about the science of colour. Over the years I have seen amazing costumes that children wear to the party and it really makes the atmosphere electric, fun and educational. 

Why not also include other dress items such as

  • Lab coats

  • Safety Glasses 

  • Name tags (with their names on - makes it easier for me when asking them to come up and do an experiment)

If you have organised a photo-booth, you will get an amazing collection of photos!
