science party ideas

Ready for a super science party? Grab your goggles and lab coats and get ready to have tons of fun playing games and performing lots of really cool experiments. Here are some of our favorite ideas to help you plan your event. Who knows what you’ll discover!

Science Party Invitations

Test Tube Invitations — Write up your science party information on a piece of paper (there are some fun scrapbooking papers with beakers or bubbles that look like floating molecules). Then roll up the paper and put it into a screw top plastic test tubes. These should either be hand delivered or sent in a padded mailing envelope.

Mad Science Invitations — Make this science party invitation by downloading the famous picture of Albert Einstein sticking his tongue out for the front image. Under it, write something like, “Come get crazy at _________’s Mad Science Party!” Then add your party information on the inside of the card.

If you are looking for online invitations, you can always find lots of great online party invitations with a free RSVP manager at Evite, or

**General Invitation Tips** — If you choose to make your own invitations, don’t forget to include the date, location, and time of your event. It is also helpful to put the host’s name, RSVP by date, and either your phone number or email.

Science Party Decorations

Here are some of our favorite science party decoration ideas:

Dress up your party space to look like a laboratory. Here’s how:

  • Biohazard Area — Make and hang the triangular yellow sign that designates an area as a biohazard zone. Use caution tape as streamers to further the look.
  • Sterile Zone Curtain — Inside the front door, hang a clear plastic dropcloth that has been cut into strips 3/4 way to the top to simulate walking into a sterile environment. (A fun idea for favors is to hand out lab coats and goggles at the door to your newly sterilized scientists.)
  • Mad Scientist Check-In Table — Set up a check-in table in your entryway for your scientists to make name badges before entering the party. (They might choose names like “Dr. Slime” or “Frank N. Stein”) Use a glow stick to perform a retinal scan on your scientists before they move on to the next area. If you have some props, like a lava lamp, a swing arm desk lamp, or science-related books, you can put these out on the table to further set the mood.
  • Bottles and Beakers — On your table and countertops, fill a variety of beakers and glass jars with different colored water (use food coloring) and different colored candies and gummy worms to create a bright party display.

Science Party Activities

Geometric Environment Design and Engineering Station – At a craft station table, set out one plastic plate for each child. In the center of the table, place bowls full of toothpicks and mini marshmallows. Let the children work to create towers, bridges, or geodomes out of toothpicks and marshmallows. You can give prizes for the tallest tower, the strongest bridge, the most creative shape, or anything you choose!

Atom Burst Game — Tie a balloon to each child’s leg near the ankle (2 per child). Then have them run around and try to burst each others’ atoms by stomping on them without theirs getting popped. The last one with a live atom wins!

Mentos Explosion— (Or the release of Carbon Dioxide Gas) Materials Needed—1 2-liter bottle of Diet Coke (Note: Use diet soda rather than regular to cut down on the sugar sticky mess)  Take your group outside for this experiment and have them step back. Drop the Mentos into the rocket tube and watch as the soda erupts into a huge geyser. (You might choose to have more than one geyser set up and have the teams see whose geyser is the highest.)

Test Tube Wonders

Gravity Goo

Make Your Own Snow

Magic Marbles


Make Flubber — Kids never get tired of this classic science activity. Here is how to make it:

Mix thoroughly:

  • 1 1/2 cups very warm water
  • 2 cups Elmer’s glue
  • food coloring (optional, as could stain clothing and skin)


In a separate bowl, mix thoroughly:

  • 1 1/3 cups very warm water
  • 2 level teaspoons Borax


Mix the contents of the two bowls together kneading until it is fully combined. Discard any remaining liquid.

Make your Own Lava Lamps

Materials Needed: Small bottles (Such as individual sized pop bottles), vegetable oil, food color, Alka-Seltzer tablets

1. Put our one bottle for each child, partially filled with vegetable oil.

2. Have the children add water to their bottles in the same proportion as the oil.

3. Have them add a few drops of food coloring to the mix. (The water and oil will separate and only the water will be colored.)

4. Have them each add an Alka-Seltzer tablet to their mixture and tightly screw their bottle cap on. (This will cause the colored water to bubble up through the oil, creating a lava lamp effect.)
Completed Lava Lamps can then be put into the children’s goody bags to take home.

Ivory Soap Soufflé

Materials Needed: 1 Bar of Ivory Soap, 1 Bar of a different brand of soap

1. Hold up the 2 soaps and ask children to predict if they will sink or float. Demonstrate by dropping the soaps into water in a bucket or your sink. (Only Ivory will float) Discuss why they think Ivory Soap floats. They might suggest that there are air pockets in the soap.

2. Cut the Ivory Soap into two pieces to show that there are no visible air pockets hiding in the soap.

3. Now the fun part… Place the Ivory Soap on a folded paper towel in the center of the microwave. Cook the soap on HIGH for 2 minutes –DO NOT OVERCOOK.

4. Be sure to watch the soap as it erupts during the cooking process into a puffy cloud of soapiness.

5. Allow the soap to cool for a minute before handling it. It will be puffy but rigid.

After the experiment, explain that all soap has water vapor inside of it, and in the case of Ivory, air that has been whipped in to the bar itself. The heat causes the trapped water to make bubbles, and the trapped air to expand, making the bar puff up in a way similar to popcorn.

* Note – Other brands of soap that don’t have air in them will just heat up and melt in the microwave.

Science Party Menu Ideas

Petri Dish Jello. A great snack idea for a science party!

Petri Dish Jell-o Surprise

What you need:

  • 2 3-ounce boxes Jell-O
  • 14 petri dishes
  • gummi worms and mini jawbreakers


Follow the quick-set directions on the Jell-O packages.
Pour the liquid mixture into petri dishes
(each package makes about seven dishes’ worth), then have the kids add candy “growths.”
Place the dishes on a tray and refrigerate for 30 minutes to set.

Fruit Ball Molecules — Use grapes, cherries (pitted), and melon balls from canteloupes, honeydew and watermelon and connect them with toothpicks to make fruity molecules!

Deviled Egg Eyeballs — Slice hard boiled eggs in half and make deviled eggs. On top of the eggs, use sliced olives for the eyeballs and sliced roasted peppers for the crazy bloodshot part.

Deviled egg eyeballs can be a fun science party food

Mad Science Juice – Serve different colored fruit drink in beakers for cups, and freeze plastic bugs or other fun items into ice cubes to float in your science concoctions!
