Introduce the idea that the objects used in music are made of matter. Ask students to name common classroom items that are matter and predict which materials might make different sounds.

Share ideas, listen, and make simple predictions about sound and material.

Set out objects made of different materials. Direct students to sort them by material type and discuss which ones might make louder, softer, higher, or lower sounds.

Sort items, compare choices, and record one observation.

Provide percussion instruments or classroom sound makers. Ask students to identify what each instrument is made of and test how the material affects sound.

Play instruments gently, identify materials, and note sound differences.

Guide students to create a simple sound maker using available materials, such as a rubber band box or cup shaker. Emphasize that the object is matter and has properties that affect sound.

Build a simple sound maker, test it, and describe the materials used.

Play a short music clip and ask students to move like different objects made of matter, such as heavy metal, light paper, or bouncing rubber. Connect movement ideas to physical properties.

Move creatively, respond to music, and connect actions to object properties.

Bring students together and review what they learned at the centers. Ask a few groups to share one fact about matter and one way material affected sound.

Share responses and listen to class discussion.

Lead a quick exit discussion: "How is matter connected to music?" Summarize that instruments and sound makers are made of matter, and their materials change the sounds we hear.

Respond orally and restate the main idea in their own words.
