Students will learn about sound and how sound moves. Students then work together to make an instrument (a kazoo) to make sound.

Students will create a musical pipe using straws of different lengths. They will create their own tune.

This parent guide supports parents in helping their child at home with the 2nd Grade Science content.

This resource accompanies our Rethink 2nd Grade Science Forces & Motion unit. It includes ideas for use, ways to support exceptional children, ways to extend learning, digital resources and tools, tips for supporting English Language Learners and students with visual and hearing impairments. There are also ideas for offline learning.

This unit was created by the Rethink Education Content Development Team. This course is aligned to the NC Standards for 2nd Grade Science in Forces & Motion.

In this lesson, students will learn about the kazoo. Students will learn about what it is, how it is made, and how sound is produced. Students will also learn how to make their own kazoo.

In this lesson, students will investigate how sounds are produced by different vibrations.

Students will explore sound by creating a "telephone" out of two empty yogurt cups and string.

In this activity, students make a record player out of simple materials and investigate how sound is produced from vibrations.

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 lesson, students will understand what a vibration is and how it relates to sound.

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 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 lesson, students will make different musical instruments in stations and discuss how each produces sound.

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.

This resource provides background information about various instruments and how they produce sound.

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 objects, string, and covering or uncovering their ears. A detailed scientific explanation follows the activity.
