The pyramid’s sides act as four mirrors, situated at 45° angles on a smartphone or tablet screen, and create a hologram-like projector.\nBy the end of this activity, students should be able to:\nuse a template to construct an open pyramid\nuse the four reflective surfaces on the pyramid to view a 3D display\nbegin to use scientific terms including ‘reflection’ and ‘angle’\nmake changes to the pyramid (and local environment) as needed to improve the specular reflection and 3D display.\nFor teachers\nIntroduction/background\nLight basics\nLight is a form of energy produced by a light source. Light can come from incandescent sources (a light bulb filament, the Sun or a flame) or luminescent sources (LEDs, computer screens and glow worms).\nRegardless of how light is produced, light travels in a straight line until it hits something else. Once light hits another surface, lots of things can happen to it, but in this activity, we will focus on the reflection of light.\nLearn more about light in the articles \u0013 HYPERLINK \"https://www.sciencelearn.org.nz/resources/171-light-basics\" \\h \u0014Light basics\u0015 and \u0013 HYPERLINK \"https://www.sciencelearn.org.nz/resources/48-reflection-of-light\" \\h \u0014Reflection of light\u0015.\nHologram projectors\nCreating an actual hologram requires the use of a laser to bounce (reflect) light off mirrors and is not something we usually do in a classroom setting due to equipment and safety issues. However, we can create a 3D projection that looks similar to a hologram.\nIn this activity, students make a transparent, four-sided pyramid. The pyramid’s sides act as four mirrors, situated at 45° angles on a smartphone or tablet screen. The screen and pyramid become a hologram projector. When used with a holographic animation video, moving 3D images (holograms) appear inside the pyramid.\nThe pyramid template comes in two sizes. Use the smaller size to create a projection on a smartphone and the larger size to create a projection on a tablet.\nUse a photocopier to print the template onto overhead projector transparencies or print the template and ask students to use a felt pen and ruler to copy the design onto the transparency/clear binding cover.\nOverhead projector transparencies and clear binding covers are available from stationery supply stores. The student handout provides a link to a YouTube video. Many other videos are available, simply do an online search for ‘3D holographic video’.\nWhat you need\nAcetate sheet(s) – for example, overhead projector transparency or clear binding cover\nCopies of the \u0013 HYPERLINK \\l \"30j0zll\" \\h \u0014template\u0015\nAccess to a photocopier or laser printer\nSmartphone or tablet\nAccess to YouTube video\nScissors\nFelt pen\nRuler\nTeaching suggestions\nBegin by exploring the information and the images in the article \u0013 HYPERLINK \"https://www.sciencelearn.org.nz/resources/48-reflection-of-light\" \\h \u0014Reflection of light\u0015.\nLook at the image \u0013 HYPERLINK \"https://www.sciencelearn.org.nz/images/45-types-of-reflection\" \\h \u0014Types of reflection\u0015 either online or in the student handout. Discuss the titles, scientific vocabulary, directionality of the arrows and the types of surfaces.\nLook at the image \u0013 HYPERLINK \\l \"gjdgxs\" \\h \u0014Activity set-up and direction of reflection\u0015 in the student handout. Discuss whether the reflection is specular or diffuse. (It is specular because the light reflects from a smooth surface. Students may require help making comparisons between the two diagrams. The specular reflection in the first diagram shows multiple arrows, while there is only one arrow in the activity set-up. The two diagrams also show the light coming in from different directions, although both are reflecting at 45° angles.)\nFollow the student instructions to construct the pyramid.\nThe projection works best in a darkened room. Some faces of the pyramid may work better than others, so try rotat","cbCaiaFUvlbmTLi0","https://ap.wps.com/l/cbCaiaFUvlbmTLi0","docx",1140802,6,"English","# Introduction/background\n## Light basics\n## Hologram projectors\n# What you need\n# Teaching suggestions\n# For students\n## What to do\n# Pyramid template","[{\"question\":\"What materials are needed to make the hologram-like projector?\",\"answer\":\"Students need acetate sheet(s) such as overhead transparency or a clear binding cover, printed copies of the template, scissors, a felt pen, and a ruler, plus a smartphone or tablet and access to a YouTube video.\"},{\"question\":\"How do students use the pyramid to create the 3D display?\",\"answer\":\"Students cut and fold the transparent four-sided pyramid so its faces act as mirrors at 45° relative to the screen.
