Proposed step by step implementation of the learning activity

1. Students begin the investigation or design task individually, in pairs, or in small groups. 
2. An unexpected problem or obstacle arises during the activity. 
3. Students identify and discuss the problem and think of possible solutions. 
4. They select one solution, gather the necessary materials or resources, and test their idea. 
5. Students evaluate whether the solution works and, if necessary, adapt their approach. 
6. The activity ends with a short reflection and class discussion about the problem-solving process.
