Students investigate how light reflects, refracts, travels, and can be blocked or filtered by solving the Great Light Detective Challenge and testing illusion ideas with an optometrist or ophthalmologist. Teams apply scientific evidence to design an accurate light-based illusion and create a performance kit containing the trick, an explanation sheet, and audience Q&A cards. Through repeated rehearsals, peer and teacher feedback, and a final dress rehearsal with a local magician or performer, students revise their science explanations, timing, and audience cues. At the Light & Illusion Showcase Night, students perform for families, explain what is really happening, answer questions, and reflect in small groups on effective choices, improvements, and responses to setbacks.
Learning goals
Students will investigate how light reflects, refracts, travels through materials, and can be blocked, filtered, or internally reflected, using observations to predict cause-and-effect outcomes. They will graph changes in shadow length and direction and use evidence about distance to explain why the Sun appears brighter than other stars. Teams will apply scientific ideas to design a safe illusion, create an accurate blueprint and Q&A cards, and revise their trick and explanation through design tests, short rehearsals, peer-teacher feedback, and coaching from an eye-care professional and local performer. During the family showcase and small-group reflection, students will communicate clearly, share team decisions, answer audience questions, and explain how feedback, setbacks, and surprises shaped their final performance.
Standards
[Next Generation Science Standards] 5-ESS1-2 - Represent data in graphical displays to reveal patterns of daily changes in length and direction of shadows, day and night, and the seasonal appearance of some stars in the night sky.
[Ohio] 5.PS.2 - Light and sound are forms of energy that behave in predictable ways.
[Next Generation Science Standards] 3-5.AF.1.3 - Ask questions that can be investigated and predict reasonable outcomes based on patterns such as cause and effect relationships.
[Next Generation Science Standards] 5-ESS1-1 - Support an argument that differences in the apparent brightness of the sun compared to other stars is due to their relative distances from Earth.
Competencies
Effective Communication - Students practice listening to understand, communicating with empathy, and share their learning through exhibiting, presenting and reflecting on their work.
Critical Thinking & Problem Solving - Students consider a variety of innovative approaches to address and understand complex questions that are authentic and important to their communities.
Collaboration - Students co-design projects with peers, exercise shared-decision making, strengthen relational agency, resolve conflict, and assume leadership roles.
Self Directed Learning - Students use teacher and peer feedback and self-reflection to monitor and direct their own learning while building self knowledge both in and out of the classroom.
Content Expertise - Students develop key competencies, skills, and dispositions with ample opportunities to apply knowledge and engage in work that matters to them.
Products
Students will create a Great Light Detective evidence board with observations, questions, predictions, and diagrams explaining the launch illusion. Teams will maintain a design portfolio containing light investigations, shadow-data graphs, prototype sketches, test results, rehearsal feedback, and documented revisions. Each team will produce a safe, original illusion using reflection, refraction, total internal reflection, or polarization, refined with feedback from peers, the teacher, an eye-care professional, and a local performer. The final Light & Illusion Showcase Night kit will include the performance-ready trick, a labeled scientific blueprint and explanation sheet, audience Q&A cards, and a brief team reflection on successes and setbacks.
Launch
Begin with the Great Light Detective Challenge: a local magician performs a safe light-based illusion while teams silently record what they notice, wonder, and think may be happening. Students rotate through stations with mirrors, water-filled containers, flashlights, and polarizing filters to test their predictions about how light reflects, bends, travels, or is blocked. Teams create evidence-based explanations, compare them with the magician’s reveal, and identify questions they still need to investigate. Conclude by asking how they can design a scientifically accurate illusion and use a science magic show to amaze an audience while explaining what is really happening.
Exhibition
Host a Light & Illusion Showcase Night for families, with each team performing its student-made trick and displaying a scientific explanation sheet that illustrates how light creates the effect. Audience members use student-created Q&A cards to ask about reflection, refraction, total internal reflection, polarization, and the team’s design revisions. A local magician helps host the show and Q&A, while an optometrist or ophthalmologist highlights accurate connections to eyes and lenses. End with small-group reflections in which students celebrate effective performance choices and explain how they handled setbacks or surprises.
