Science Party Invites

Science Party Invitation Ideas

If you have time, it’s always fun to create your own birthday party invitations, especially since it’s something you can work on with your child. Here are some crafty ideas that will get your party guests excited for your science party:

  • Cut a piece of construction paper into the shape of a flask. At the bottom of the flask, cover the area with glue and sprinkle green glitter over the surface. At the top of the flask write the party details.
  • Attach your invitation to a vial of touchable bubbles, which come in a neon test tube and don’t pop. You can also include safety goggles, a child-sized lab coat or a cool rock with your invitation.
  • Buy mini plastic clipboards and write your party details in a list format on an index card. Clip the index card to the clipboard and deliver to your party guests.
  • Print out a card-sized image of the periodic table of elements. On the back of the picture, write the following poem.

Put your safety goggles on and get ready to discover,

A birthday party for a true science lover!

Decorating & Food Ideas

Science Party Decor

Science Party Decoration Ideas

For balloons, streamerspartyware and cutlery, we suggest using the colors lime green, orange and bright blue. Here are some more creative ways you can turn your home into a science lab:

  • If you child has completed any science projects recently, be sure to display them around the room.
  • Grow rock crystals several weeks before the party and display them in the party area.
  • Label a table “weird science” and place putty and goopy or odd toys on the table. You can also place rulers, a clipboard, pens, beakers with water, and food coloring on the table. See what weird things your guests make!
  • Place a large periodic table of elements on the wall or cut squares out of construction paper and write a different element on each and tape them to the walls.
  • Set up plastic microscopes and slides away from the food area. Prepare some slides with things the children can look at, such as grass, a leaf, a piece of candy, a fingernail, fabric or other interesting items.
  • Drape a child-sized lab coat on the back of each chair at the party table. If the lab coats have pockets, you can put a pen and pencil in each one.
  • Hang a yellow sign that reads “Safety Glasses Must Be Worn at All Times.” You can also hang a banner at your front door that reads “Caution, Mad Scientists at Work.”

Science Party Food

Science Party Food Ideas

In addition to party favorites like chicken fingers, hamburgers, or hotdogs, here’s how to add some scientific fun to the food table:

  • Molecular Fruit: Use a melon baller to scoop fruit such as watermelon, cantaloupe and honeydew into balls. Attach them together with toothpicks so that they look like molecule chains. You can also use grapes and blueberries.
  • Elemental Sandwiches: Cut grilled cheese, or turkey and cheese sandwiches into fourths. On each sandwich square write an element’s periodic table abbreviation (Ar, He, H, Pb, Au, etc.) with Kraft Easy Cheese.
  • Pizza Science: Cooking is a science too! Allow the children to create their own pizza by providing them an assortment of toppings and small pizza dough. In addition to common pizza toppings, you can provide some more interesting choices such as shredded cheese, pineapple, grilled chicken, Alfredo sauce and hot dog slices.
  • Beaker Soda: Serve fizzy drinks in clean, new beakers. Green soda like Mountain Dew or lemon lime fruit juice would look perfect with a gummy worm draped over the side of the beaker!
  • Test Tube Jell-O: Prepare green or blue Jell-O according to the package and serve in test tubes.

Science Cupcake Idea

Make cupcakes for your little scientists that use their initials as the decorations. Simply follow the directions below and use our picture as your reference.

  1. First, bake cupcakes using one of our cake batter recipes.
  2. Prepare buttercream or vanilla frosting and separate evenly into six bowls.
  3. In each bowl of frosting, add 3-5 drops of food coloring. Each bowl of frosting should be red, blue, orange, yellow, green or purple.
  4. Frost the cupcakes in different colors.
  5. Use black piped icing to write each guest’s initials on a cupcake. The first letter should be capitalized and the second letter should be lowercase. For example, if a child’s name was John Smith, you would write “Js” on the cupcake. This way, the cupcakes will look like periodic element abbreviations!
  6. Arrange all the cupcakes in groups by color in the shape of the periodic table and serve.
