FOCUS: Sound is what we hear when something is vibrating. The vibrating object – whether a violin string, a singing bird, or a gurgling brook – creates a sound wave that travels to our ears, where we interpret its meaning. Sound waves need a medium like air, water, or a solid through which to move; they cannot pass through a vacuum. The Earth’s atmosphere, hydrosphere, and geosphere provide a way for sounds to travel. Many animals depend on sound to learn about their surroundings and to communicate with others of their kind.
Objective: To begin to explore and ask questions about sound.
Ask children to put their hands on their own throats as they make a noise like a frog and sing like a bird. What do they notice? Next, ask all children to make a “shush” sound. Do they notice a difference?
PUPPET SHOW “Calls of the Wild”
Objective: To learn how different animals hear and make sounds, and how sounds are important in their lives.
Perform the puppet show, or have a group of children perform it for the class. Afterward, ask questions to review the key details and vocabulary in the story. How was sound important to the different animals in the puppet show? (Chickadee – contact calls, listening for danger; woodpecker – finding food, advertising territory; jay – alarm, warning others; hare – knowing the weather, knowing where he is, listening for predators.) What are some other ways that sound is important in our lives or those of animals? (Calling for help, young begging for food, crossing roads, enjoying music, speaking, etc.)
Materials: puppets, script, stage, three signs for audience participation.
PAINT STICK ORCHESTRA
Objective: To investigate what is happening when something makes a sound.
Give each child or pair of children a paint stick. Have one child place the stick flat on a table or desk, so that about two thirds of it extends out beyond the edge. Continue reading Nature of Sound – Activities
