Bring the science of light and reflection to life with this engaging STEM challenge designed for upper primary school students (grades 4-6). This hands-on STEM unit combines inquiry-based learning, engineering design, and problem-solving as students investigate the science of how light travels, reflects, and can be used to solve real-world challenges.
.
.
Students begin by exploring the properties of light through interactive experiments and investigations. Using mirrors and directed light sources, they discover how reflection works and develop a deeper understanding of key physical science concepts. As their knowledge grows, students receive an exciting mission from “Headquarters”: a secret agent has gone missing, and they must design and build a device that allows the agent to see over walls and around corners without being detected by an evil supervillain.

.
Using the engineering design process, students plan, create, test, and improve their own working devices while applying their understanding of light and reflection. This exciting STEM engineering challenge encourages critical thinking, creativity, collaboration, and perseverance.
.
.
The unit culminates in a fun obstacle course challenge and/or pattern relay where students test their inventions, solve clues, and complete mission-based tasks. These engaging activities provide authentic opportunities to apply scientific knowledge in a meaningful context.
