In the previous lesson, students began planning and conducting investigations of sound. Use tools and materials to design and build a device that uses light or sound to solve the problem of communicating over a distance. Plan and conduct investigations to provide evidence that vibrating materials can make sound and that sound can make materials vibrate. For the first half, we are investigating the question, "How do we communicate with sound?" This essential question incorporates two NGSS standards as we are beginning to investigate the properties of sound and also moving towards the culminating engineering design product. ![]() ![]() This unit is broken down into two main parts: sound and light.
