- Invisible results during experiments: If the rainbow does not appear, the teacher supports inquiry with guiding questions like: “What could we try differently?” Don’t treat failure as a mistake — encourage it as a new opportunity to try again.
- Groups working at different speeds: Prepare differentiated worksheets with optional extra questions or colouring templates for rainbows.
- Poor lighting conditions: Use alternatives such as a video, projected images, or LED light sources.
- Maintaining focus: Turn experiments into short challenges, e.g., “You have 5 minutes to observe as many colours as possible!”
- Fostering a sense of community: Let students create a large collaborative rainbow collage and offer each a “Young Explorer Certificate” at the end.
