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

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 investigate how sounds are produced by different vibrations.

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

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.

Students will work individually to design and build an instrument out of provided materials to make the loudest instrument they can. Students will need to work out what materials will cause vibrations in order to make sound. Students will be allowed to touch and plan before design as well as have time to fix and rebuild. The students will need at least an introduction to instruments and how their sound is created.

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

In this lesson, students will explore how sound travels through the air and how sound interacts with the eardrum. Students will stretch plastic wrap across a bowl, place rice grains on top, and make observations when a noise is made close to the bowls. Students can experiment with different sizes of bowls and varying volumes of the noises.

Students will explore the relationship of vibration and sound in this lesson by making sound wave vibrations on various instruments and classroom materials. Students will then work in groups or in a whole class setting to classify the sounds made using a reproducible chart included in the lesson. A class discussion of the concepts of actions causing vibration and vibration causing sound completes the lesson.

In this lesson, students learn that sound is a form of energy and will understand and explore how different sounds may be made by making a variety of materials vibrate.

Driving Question: How can I, as a 1st grade engineer, design a device to let people know I am safe, using light and sound?

Students learn about the human ear and the basic information about each part of the ear (structure and function) and how the ears are used for hearing and balance of the body. Text for this article is appropriate for the elementary level. A Spanish version of the article and a read-aloud option are also provided on the site. This resource supports the English language development of English language learners.
