In this multi-week project, 4th graders act as “community scientists” to solve the challenge of creating long-lasting bubbles. Students develop critical thinking by following the scientific method to test how changing different ingredients affects their results. Teams practice problem-solving and creativity by designing various wands and fixing designs when bubbles pop too early. The project strengthens connectedness and responsibility as students plan a safe and sustainable bubble event for their school community. By analysing their data and trying again, students build resilience and learn that every failed test provides important evidence for improvement.
SPIRIT Skill Focus
- Problem-solving
- Curiosity, sense of wonder and openness

- Valuing people and nature
Basic Information Sheet
| Age group | Student number | Duration | Number of stages | Subjects connection and relevance |
| 4th-6th grade students | Whole class (max. 30 students) working in teams | 8 sessions of ~45–60 minutes each (over ~3–4 weeks) + community bubble event | 8 stages | Science (scientific method, materials, mixtures, variables, data, conclusions) + community/civic engagement (embedded) |
National curriculum Link and Objectives
- Understand and apply the scientific method: observation → question → hypothesis → experiment → analysis → conclusion → iteration.
- Identify and control variables in fair tests (change one thing at a time).
- Collect, record, and interpret empirical data (bubble size, longevity, quality notes, environmental conditions).
- Make evidence-based decisions using comparisons and patterns.
- Plan and implement a real-world outcome for a real audience (school community), including safety and sustainability choices.
