In this lesson, Students will learn about the laws of reflections through an inquiry-based introductions activity and then apply what they learn to create a laser maze. In the main portion of the lessons, students will be tasked with building a laser system that can be used to protect 9 precious gems in an exhibit hall. Their goal will be to plan, design and build a system of mirrors that reflect a single laser beam to ensure that each of the gems is protected from theft. Students will be asked to demonstrate their laser maze and present how it is used to protect their gem collection. This lesson supports the grade 10 science curriculum and includes a variety of vocabulary strategies that will support FSL learners.
