In ten lessons, students investigate how sound is made, how we see and how light passes through different materials. At the end they send their own messages with light and with sound. In every lesson students test something themselves and explain with what they observed.\u003c\/p\u003e\n\u003cp\u003eThe sound lessons start with what students can feel. First they notice a gentle vibration. Then they make a ruler sound and see that vibration and sound go together. In Lesson 3, sound moves a light object, so students can see that sound has an effect. The light lessons begin with a dark box. Students find that they can only see inside when light gets in. Next they test materials. Light passes through clear material, only partly through cloudy material and not at all through opaque material. The shadow investigation builds on this. The last two lessons are small design tasks, where students send a message across a distance with light and then with sound. Each lesson uses the same learning routine, introduced on the opening page, and students track their work in a learning record.\u003c\/p\u003e\n\u003ch2\u003eWhat's Included\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003eClassroom Material: 33 pages (PDF)\u003c\/li\u003e\n\u003cli\u003eTeacher Guide: 14 pages (PDF)\u003c\/li\u003e\n\u003cli\u003e47 pages in total\u003c\/li\u003e\n\u003cli\u003eEditable DOCX text version (pagination may differ)\u003c\/li\u003e\n\u003cli\u003eEditable PowerPoint presentation (PPTX, editable text)\u003c\/li\u003e\n\u003cli\u003ePrint-ready A4 PDF that prints on US Letter with fit-to-page\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch2\u003eThe 10 Investigations\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eSound and vibration (Lessons 1–3).\u003c\/strong\u003e Feel a gentle vibration; A ruler makes sound; Sound moves a light object.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLight and seeing (Lesson 4).\u003c\/strong\u003e Seeing in a dark box.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLight and materials (Lessons 5–8).\u003c\/strong\u003e Clear material; Cloudy material; Opaque material; Shadow investigation.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCommunicate over distance (Lessons 9–10).\u003c\/strong\u003e Send a light message; Send a sound message.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eAlso included.\u003c\/strong\u003e An opening page on the learning routine and a student learning record.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch2\u003eStudents Will Learn To\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003eShow that vibrating materials make sound and that sound can make materials vibrate\u003c\/li\u003e\n\u003cli\u003eExplain that objects can be seen only when light is present\u003c\/li\u003e\n\u003cli\u003eSort materials as clear, cloudy or opaque by testing how light passes through\u003c\/li\u003e\n\u003cli\u003eExplain how a shadow forms\u003c\/li\u003e\n\u003cli\u003eUse light or sound to send a message across a distance\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch2\u003ePerfect For\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003eGrade 1 physical science units\u003c\/li\u003e\n\u003cli\u003eScience stations with simple classroom materials\u003c\/li\u003e\n\u003cli\u003eSTEM time with a small design challenge\u003c\/li\u003e\n\u003cli\u003eGrade 2 students who need a review of light and sound\u003c\/li\u003e\n\u003cli\u003eHomeschool science with household items\u003c\/li\u003e\n\u003cli\u003eUK and Australia: roughly maps to Year 2 in England and Year 1 in Australia\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch2\u003eWhy Teachers Choose This Unit\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003eThe teacher guide includes an NGSS mapping and notes on assessment.\u003c\/li\u003e\n\u003cli\u003eEach investigation has its own answers and teaching decisions page.\u003c\/li\u003e\n\u003cli\u003eThe guide sets out the teaching concept and planning for the whole unit.\u003c\/li\u003e\n\u003cli\u003eAn observation and responsive support section helps you respond to student ideas during investigations.\u003c\/li\u003e\n\u003cli\u003eStudents explain with evidence from their own tests, not from a reading passage.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e\u003cem\u003eCreated with AI assistance.
