Students will engage in observation and interaction with sound to better understand vibrations, volume and pitch, and the different mediums that sound can travel through.
In this classroom activity, students will discover that when objects vibrate a …
In this classroom activity, students will discover that when objects vibrate a sound is produced. Students will first observe different sound sources such as a music box or sound-making toys. They will then list their observations and come up with an answer to the question "How is sound made?" Groups will then come up with ways to test their conclusion to how sound is made and share with the class. As a class, students will conclude that vibrations cause sound and that a sound source is an object that is vibrating and a sound receiver is what detects sound vibrations.

In this lesson, students will observe a demonstration on water bottles being played as instruments with different amounts of water in them. They will then investigate further by experimenting with water bottle liquids, rulers, or straws to determine how size or length of object affects pitch.
In this lesson, students explore the concept of sound by creating a …
In this lesson, students explore the concept of sound by creating a paper straw instrument. Students work in groups to experiment with changes in tone and pitch by changing the length of the straws. At the conclusion of the lesson, students are asked to write a paragraph explaining how sound was produced in the straw and why the pitch changed. A diagram of how to cut the straws properly in preparation for the lesson is included.
In this activity, students will be able to visualize, and thus better …
In this activity, students will be able to visualize, and thus better understand, the vibrations that sound makes through this simple project. They will set up an apparatus made of common materials and use light and a mirror to make sound waves visible.
The Sound unit explains what sound is, how it travels, and some …
The Sound unit explains what sound is, how it travels, and some of the properties of sound, such as pitcha nd volume. It explores how ears hear and encourages students to take care of their ears. In the unit introduction activity, students will listen to sounds of a pencil tapping objects and try and guess what each object is made of.
Students will investigate how sound reaches the ears by experimenting with metal …
Students will investigate how sound reaches the ears by experimenting with metal objects, string, and covering or uncovering their ears. A detailed scientific explanation follows the activity.
Students will learn how sound travels. Students will experiment with a ruler …
Students will learn how sound travels. Students will experiment with a ruler being bent on a desk to see if they can see the vibrations and hear the sound. Students will be partnered up to experiment with a hanger and cups.
