Bubbles are a great way to have fun and explore the properties of air, water, color, and light at the same time. Have children really observe the bubbles that you make this month.

Ask:
How are bubbles made? How can you figure it out?

Experiment:
Have children experiment with different bubble wands. Have them design and test different bubble wands from any of these materials: drinking straws, pipe cleaners, string, six-pack plastic rings, funnels, and paper cups.

Discuss:
Talk about these bubble facts: Bubbles are made up of air surrounded by a thin film of water. The film, or skin, wraps around moving air, trapping the air within. A soapy solution allows the "skin" of the water to stretch. Soapy bubbles are stronger than plain ones because the soap lessens the surface tension, allowing the skin to stretch.

Bubble Recipe:

Mix 2 cups water,
¼ cup liquid soap,
and 1 teaspoon sugar.
Stir.
Dip bubble wand in and blow!
