Sc 8 Unit C Light and Optics Links Science 8 This is new resource from LearnAlberta. It contains learning resources that address topics from the junior high science curriculum: Light and Optical Systems. The resource includes interactive Gizmos licensed from ExploreLearning. The topics include: The Penumbra Effect Additive Color v2 Subtractive Color v2 User ID LA15 password 9544 2Learn.ca Unit A science interactive links. ScienceFocus Internet links for Unit 3. Science Focus 8 Student Resources Study tips, quizzes, and cool things to do. Science In Action 8 Hotlinks Science In Action 8 Tech Ideas Light and Optics Interactives Light Terms Glossary Students use a PowerPoint template to provide definitions, examples, and graphics for terms used in Unit 3, Light and Optical Systems. Light and Lenses A Light Sampler Students will interact with the content of five different Web sites, all of which deal with different "light and optical" concepts. They will then choose one of the Web sites and evaluate it in terms of its usefulness, format, content, as well as its applicability to the light and optical unit. An Edmonton Public Schools ICT project. Science, Optics and You Follow the links to explore some of the Java-based interactive tutorials that reveal the mysteries of light and optical systems. What is Light? Internetconnect Topic 1 Optics for Kids Explore the basic concepts about light, and optics. Penumbra Effect This ExploreLearning Gizmo allows the user to gain an understanding of how partial shadows are created. The simulation features multiple light sources and adjustable light spacing. The width of the shadow-casting block and light distance can also be changed and the resultant cast shadow observed. Screen shots may be taken to record data. The resource includes an exploration guide and assessment questions. Reflection Internetconnect Topic 2 Concave Mirrors-Real Images Concave Mirrors-Virtual Images Convex Mirrors-Virtual Images Refraction Internetconnect Topic 3 Light and Optics Virtual labs and simulations for interactive learning. Lessons and labs for reflection, refraction and lens optics. Refraction of Light Using a Lens Concave and Convex Mirrors Internetconnect Topic 4 Lenses and Vision Internetconnect Topic 5 Eyeball Challenge: Mission 1 Students investigate a range of animal eyes (dog, cat, bee, fish, eagle and human) and discover that these animals see things in different ways because their eyes have different structures. Students then find their way through an ancient temple by choosing eyes suited to avoiding hazards and solving puzzles. Reading Between the Lines Using this interactive resource from The Learning Federation, students can explore three of the more common types of vision problems: myopia (short-sightedness) and hyperopia (far-sightedness). The resource allows students to compare effects of corrective lenses on reading at different distances. Students view a cross-section of the eye that illustrates focal variations causing each vision problem. Glossary terms, background information, and challenges to test and extend the student’s knowledge are also included. Far Out Lenses Using this interactive resource from The Learning Federation, students can simulate building a telescope using two convex lenses to look at the moon. Students first choose the focal length of the two lenses: the eyepiece lens and the objective lens. They can then move the objective lens to focus the telescope. The resource allows students to determine which lens pair produces the greatest and least magnification. Background information and glossary terms are also included. Laser Eye Surgery Webquest Simple Magnification A magnifying glass is a bi-convex lens. It is convex on both sides, meaning that the glass is curved outward to form a dome. Things look bigger looking through convex lenses. Microscope Magnification Eye Site Your one stop source of information about eyes. Topics include eye anatomy, ailments, eye games and activities. Another net nugget from Mr. Slade. The Eye: Structure And Function Students will research the diversity of eyes in order to prepare an illustrated report about the eye of one type of animal. Eye, Eye, Eye, Eye: Questions About Eyes Whose Eye Is It Anyway? Extending Human Vision Internetconnect Topic 6 Microscope Magnification A microscope is a tool used by scientists to make things appear larger than they really are. This site allows you to look at a variety of specimens using different magnifications. How Cameras Work Cameras combine optical, chemical and mechanical processes in a simple, yet amazing device. Get inside a single lens reflex camera. How Night Vision Works Learn how night-vision goggles work. The Source of Colours Internetconnect Topic 7 Additive Color v2 This ExploreLearning Gizmo allows the user manipulate the intensity of simulated spotlights in primary colours (red, green, and blue) and observe the resulting secondary colours which comprise the remainder of the visible spectrum. The RGB values of the overlapping areas are measurable. The resource includes an exploration guide and assessment questions. Subtractive Color v2 This ExploreLearning Gizmo allows users to move spots of yellow, cyan, and magenta paint on a white surface. As the colours overlap, other colours can be seen due to colour subtraction. The intensity of the cyan, magenta, and yellow can be adjusted, and the RGB (red, green, blue) values at any location can be measured. An exploration guide and assessment questions are included. Resolution and Colour Depth Mix n Match You can mix just three colors of light to make over 16 million different colors! Mixing Primary Colours Primary Additive Colours Java Tutorial Subtractive Primary Colours Java Tutorial Single Filter Emission Java Applet This applet allows you to place a single, pure colored filter on a lamp. The lamp's light can be set by three scroll bars (red, green, and blue). The color of the filter can be selected. Colour In Dots Discover how colour pictures in magazines are produced using tiny coloured dots. Colour Wheels Optical illusions based on movement can be constructed in a variety of ways. Here we explore color wheels (with adjustable speeds) using simple patterns that create some spectacular optical illusions. The Wave Model of Light Internetconnect Topic 8 Electromagnetic Spectrum This virtual lab has a worksheet. Spectrum Use this java applet to discover the relationship between wavelength and energy.
