Have you seen a square bubble?
Bubbles form because of the surface tension of water. Water is polar: hydrogen atoms in a water molecule are attracted to oxygen atoms in other water molecules. So water molecules cling together.
The surface tension of water alone is too strong to make good bubbles. Adding soap to water reduces surface tension and adds an oily film that slows evaporation for longer lasting bubbles.
Simple structures make the best bubbles.
Start with 8 liters of warm water in a bucket or deep sink. Use a container at least 30 cm (one foot) in diameter and at least 30 cm (one foot) deep. A large bucket is ideal, or try a rectangular file box (from any office store).
Add 1/2 cup of liquid dishwashing detergent. Mix the bubble solution gently and remove excess foam.
For tougher, longer lasting bubbles, add 1 tablespoon glycerin.
Making the Bubbles
Working in groups promotes valuable team skills. By discussing the challenges of a group project, students practise communication in mathematical language, and draw deeper understanding from the observations of their team members.
No previous knowledge required
Students with a wide range of proficiency levels achieve excellent results exploring concepts with Zome System.
Activities do not require specific levels of language comprehension. Students explore universal concepts accessible to everyone, regardless of cultural background. Activites may be used to promote language skills in English as a Second Language classes.
Recording created Bubbles
Children are very proud of the bubbles they create.
Use a camera to record achievements and create a visual reminder of the concepts learned.
The components will fade and become brittle with prolonged expose to sunlight. Dirty parts can be washed in a garment bag in a washing machine. Zome System components are made of high quality ABS plastic and are very durable.
Ozpod Pty Ltd supplies Zome System to educators, children, specialty retailers, scientific institutions, and experimental users in Australia.
