Entry Events
Events that will be used to introduce the project to studentsUnseen Light Challenge
**The "Unseen Light" Challenge:** Students are presented with seemingly impossible scenarios, like seeing around corners or communicating without visible signals. They must use their initial understanding of light's properties to propose preliminary solutions, sparking curiosity and highlighting the need for deeper knowledge. This connects directly to understanding light's behavior and challenges conventional ideas about its limitations.Light and Crime
**Light as an Interrogation Tool:** A crime scene investigation simulation where students analyze light patterns, shadows, and reflections to solve a mystery. This activity will require student to utilize properties of light to determine events that are not directly observable. This event will relate to student experiences from popular culture.Light Bending Reality
**"Light Bending Reality" Art Installation:** Students view and critique an exhibit of optical illusions and light-based art, then brainstorm their own interactive installation concepts. This encourages creative thinking about how light can be manipulated and perceived. This event directly relates to student interests in art and design while also providing an innovative approach to understanding light's properties.Light Based Invention
**The "Greatest Light-Based Invention" Pitch:** Each student researches and presents a pitch for a light-based technology that could solve a current global challenge (e.g., clean energy, communication). This fosters innovative thinking, connects to real-world problems, and necessitates a deep understanding of light's potential. This activity encourages students to think critically about the application of their knowledge.Decoding the Universe
**"Decoding the Universe with Light"**: Students analyze real astronomical data (spectra of stars, Hubble images) to uncover the secrets of distant celestial objects. This entry event will allow students to relate properties of light to real world phenomenon.Portfolio Activities
