The Topic: 

Easier - Bubbles are round pockets of air or other gases in liquid (such as boiling water, fizzy drinks) or solid materials (plastic, glass). Bubbles can also be a thin, ball-shaped film of liquid that has gas trapped inside.
Harder - A bubble is a spherical mass of gas surrounded by a liquid or solid.
Soap bubbles are shaped by an equilibrium between their outward air pressure and the inward surface tension of the soap film. The detergent molecules tend to line up with one end pointing inward and the other outward, making the liquid surface more stable. The thickness of the soap film layer is due to these detergent molecules and is uniform for all size bubbles. Colors are seen because of the light diffraction through the soap film.

Find out everything that you need to know about bubbles.
What is so fascinating about bubbles? The precise spherical shape, the incredibly fragile nature of the microscopically thin soap film, the beautiful colors that swirl and shimmer, or most likely, a combination of all these phenomena? Let's look at the forces that mold bubbles.
Blowing Bubbles: Good Clean Fun (FamilyFun Magazine)
To blow a stream of beautiful bubbles, kids need only a casual knowledge of soap science. A delightful way to introduce the subject is with a homemade bubble factory.
Thinking Fountain: Bubble Geometry (Univ. of Minnesota)
Create bubble wands out of found objects (straws, pipe cleaners, strawberry baskets and coat hangers) and have your own bubble festival (This is a small site with pictures and some good probing questions about bubbles).
 Explore several of the websites below; then complete a bubble project or activity:
Bubbles and Balloons. After learning about bubbles at Professor Bubbles' Bubblesphere and Bubbles, explain how bubbles and balloons are alike and how they are different.
Write a Bubble Poem. Compose a poem about bubbles. Illustrate your poetry with an illustration created with KidPix. To read a bubble poem, go to an Ode to a Bubble.
Have a Bubble Contest. Using a recipe from Super Soap Bubbles, Bubbles, or Bubbles66, create your own bubble solution. You can also get good ideas at Soap Bubbles, Bubbles-Science World, and Amazing Bubbles. Experiment to find out what the best formula is; try increasing and decreasing the ingredients. Keep a log of your results. Visit Thinking Fountain: Bubble Geometry and then try constructing unique, different-shaped bubble wands. Use different materials to construct the wands. Find out which ones work the best. Photograph your competition. As a fun finale, have a bubble gum blowing contest.
Try Some Bubble Experiments. Learn more about bubbles by completing some experiments. You can experiment by making bubbles and antibubbles. You can investigate what kind of milk makes the best bubbles. Have fun with one or more of these.
