Students study the properties of air, water, color, and light while having fun with bubbles!
- Grades: PreK–K
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.
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.
Mix 2 cups water,
1/4 cup liquid soap,
and 1 teaspoon sugar.
Dip bubble wand in and blow!
