During the study of light and sound waves students will develop their science skills through inquiry, prediction, observation, exploration, discussion and recording. These lessons focus on students collaboratively problem solving, discovering and investigating to find answers and solutions. They will answer questions such as; What happens when materials vibrate? What objects can be used to communicate over a distance? What happens when light is blocked or when materials of different kinds are placed in the path of a beam of light? Each lesson includes science and engineering practices, disciplinary core ideas and crosscutting concepts which are a part of Next Generation Science Standards.
