NGSS Connections: PS4.B Electromagnetic Radiation

• Make observations to construct an evidence-based account that objects in darkness can be seen only when illuminated (1-PS4-2)
• Plan and conduct investigations to determine the effect of placing objects made with different materials in the path of a beam of light. (1-PS4-3)
• Some materials allow light to pass through them, others allow only some light through and other block all the light and create a dark shadow on any surface beyond them, where the light cannot reach. Mirrors can be used to redirect a light beam. (1-PS4-3)
• Develop a model to describe that light reflecting from objects and entering the eye allows objects to be seen.
• The path that light travels can be traced as straight lines, except at surfaces between different transparent materials (e.g., air and water, air and glass) where the light path bends (MS-PS4-2)
