In this 3-stage STEAM program, 2nd-grade students explore the science of rainbows through storytelling and hands-on experiments. Children use mirrors, CDs, and water spray bottles to investigate how light and water interact to create different colors. The activity builds critical thinking and curiosity as students observe natural phenomena and test their own scientific ideas. Students develop problem-solving and flexibility skills by adjusting their tools and light sources to get the best results. The project concludes with artistic drawing and group reflection, helping children value nature and think step-by-step like scientists.

Brief description of the STEAM program

In this STEAM activity, teachers guide second-grade students in exploring the natural phenomenon of rainbows through storytelling, hands-on experimentation, and creative expression. Students investigate how light and water interact by working with simple tools such as mirrors, water, spray bottles, CDs, and prisms. Through guided inquiry, observation, and discussion, children move from curiosity and questions toward basic scientific explanations, while also expressing their understanding through art. The activity is multi-sensory, inquiry-based, and age-appropriate, supporting early scientific thinking, creativity, collaboration, and reflective learning.
