Optics Subtask 9 OPTICS - SEEING IS BELIEVING! Energy and Control An Integrated Unit for Grade 8 mins240 Notes to Teacher 1. A review of the properties of light might include: a) Light travels in straight lines and its intensity decreases with distance from its source. b) Light reflects from a plane mirror according to the law of reflection. c) Light is refracted by transparent materials. d) Light is a form of energy e) The visible light spectrum is made up of different colours f) Visible light is only

Students will then classify the materials. 4. Hand out the blackline master, "Shining <span class="highlight">Light</span> at Various Objects" (BLM 8.4.1). The students, working <span class="highlight">in</span> pairs, will have 20 minutes to complete this task. Quickly review the task: - using the flashlight <span class="highlight">in</span> a dark area or <span class="highlight">in</span> the darkened room - shine a <span class="highlight">light</span> <span class="highlight">on</span> a variety of objects/materials - record your observations <span class="highlight">in</span> the "results" column of the sheet

Page 12 5.1.1 Indirect Lighting Indirect lighting uses fluorescent or metal halide lamps to up light a light color ceiling; the resulting reflected light is inherently very soft, shadow-free, and low-glare. Indirect lighting works well for both paper-based and computer tasks in rooms where the ceiling height is at least 9'-6" and preferably more than 10'-0". 5.1.2 Direct Lighting Direct lighting uses down lights to illuminate the reading tables. The down lights can be as small

All of the <span class="highlight">light</span> is reflected off the ceiling, so the illumination <span class="highlight">on</span> the stacks is very <span class="highlight">soft</span>, and the entire range of stacks appears
