Explore bending of light between two media with different indices of refraction. See how changing from air to water to glass changes the bending angle. Play with prisms of different shapes and make rainbows.

Students work in groups to create soap bubbles on a smooth surface, recording their observations from which they formulate theories to explain what they see (color swirls on the bubble surfaces caused by refraction). Then they apply this theory to thin films in general, including porous films used in biosensors, listing factors that could change the color(s) that become visible to the naked eye, and learn how those factors can be manipulated to give information on gene detection. Finally (by experimentation or video), students see what happens when water is dropped onto the surface of a Bragg mirror.

Students explore the many different ways that engineers provide natural lighting to interior spaces. They analyze various methods of daylighting by constructing model houses from foam core board and simulating the sun with a desk lamp. Teams design a daylighting system for their model houses based on their observations and calculations of the optimal use of available sunlight to their structure.

Students are introduced to sound energy concepts and how engineers use sound energy. Through hands-on activities and demonstrations, students examine how we know sound exists by listening to and seeing sound waves. They learn to describe sound in terms of its pitch, volume and frequency. They explore how sound waves move through liquids, solids and gases. They also identify the different pitches and frequencies, and create high- and low-pitch sound waves.

In a hands-on way, students explore light's properties of absorption, reflection, transmission and refraction through various experimental stations within the classroom. To understand absorption, reflection and transmission, they shine flashlights on a number of preselected objects. To understand refraction, students create indoor rainbows. An understanding of the fundamental properties of light is essential to designing an invisible laser security system.

Students learn and use the properties of light to solve the following challenge: "A mummified troll was discovered this summer at our school and it has generated lots of interest worldwide. The principal asked us, the technology classes, to design a security system that alerts the police if someone tries to pilfer our prized possession. How can we construct a system that allows visitors to view our artifact during the day, but invisibly protects it at night in a cost-effective way?"
Students learn the basic properties of light the concepts of light absorption, …
Students learn the basic properties of light the concepts of light absorption, transmission, reflection and refraction, as well as the behavior of light during interference. Lecture information briefly addresses the electromagnetic spectrum and then provides more in-depth information on visible light. With this knowledge, students better understand lasers and are better prepared to design a security system for the mummified troll.
Through an introduction to the design of lighting systems and the electromagnetic …
Through an introduction to the design of lighting systems and the electromagnetic spectrum, students learn about the concept of daylighting as well as two types of light bulbs (lamps) often used in energy-efficient lighting design.
Students learn about the basic properties of light and how light interacts …
Students learn about the basic properties of light and how light interacts with objects. They are introduced to the additive and subtractive color systems, and the phenomena of refraction. Students further explore the differences between the additive and subtractive color systems via predictions, observations and analysis during three demonstrations. These topics help students gain a better understanding of how light is connected to color, bringing them closer to answering an overarching engineering challenge question.
Students examine various materials to investigate how they interact with light. They …
Students examine various materials to investigate how they interact with light. They use five characteristicsâtranslucency, transparency, opaqueness, reflectivity and refractivityâto describe how light interacts with the objects.
Students determine the refractive index of a liquid with a simple technique …
Students determine the refractive index of a liquid with a simple technique using a semi-circular hollow block. Then they predict the refractive index of a material (a Pyrex glass tube) by matching it with the known refractive index of a liquid using the percent light transmission measurement. The homemade light intensity detector uses an LED and multimeter, which are relatively inexpensive (and readily available) compared to commercially available measurement instruments.
This is the first lesson of this unit to introduce light. Lessons …
This is the first lesson of this unit to introduce light. Lessons 1-5 focus on sound, while 6-9 focus on light. In this lesson, students learn the five words that describe how light interacts with objects: "transparent," "translucent," "opaque," "reflection" and "refraction."

The following resource contains the assets (or resources) to accompany the Sask DLC Science 8 course. Please note that this is not the content of the course, but the assets used to support and deliver it. The files are organized in a zip folder and a collection.
Students learn the relevant equations for refraction (index of refraction, Snell's law) …
Students learn the relevant equations for refraction (index of refraction, Snell's law) and how to use them to predict the behavior of light waves in specified scenarios. After a brief review of the concept of refraction (as learned in the previous lesson), the equations along with their units and variable definitions, are introduced. Student groups work through a few example conceptual and mathematical problems and receive feedback on their work. Then students conduct the associated activity during which they practice using the equations in a problem set, examine data from a porous film like those used in biosensors, and apply the equations they learned to a hypothetical scenario involving biosensors.
