Grade: 4th

Standards:

• 4-PS4-1. Develop a model of waves to describe patterns in terms of amplitude and wavelength and that waves can cause objects to move.

Summary:

After this lesson, students will understand that different waves have different properties. Students get to move about the room and practice making waves of different kinds using jump ropes, slinkys, or their class-made wave machine. Predicting what they think needs to happen to produce waves of higher amplitude will lead to the realization of more energy equals a higher amplitude.

Focus Questions:

• What is amplitude?

• What do you predict needs to happen to produce waves of higher amplitude?

• Is there a difference in waves as they move away from the initial point? Describe it

• What is needed to make a particle move through a large distance?

Summary:

Students will learn about vibration and why it is so important to sound. Additionally, they will be able to describe how sound works and the ways that sound can be changed.

Focus Questions:

• What happens when things vibrate? How do you know?

• What does sound do?

• What are vibrations?

Summary:

How can people communicate from far away? What ways can we use sound to alert someone to an emergency or that they need to give us attention? Students will learn about how people communicate from far away with and without using sound. At the end of the lesson, students can try an experiment.

Focus Questions:

• How do we communicate over long distances without using sound?

• If you needed someone to hear you from far away, what can you do?

• Other than light and sound, how else do we communicate?

Summary:

In this video, students explore waves, the different vocabulary words related to waves, and how waves help us hear. Common items like water and slinkies are used to help students visualize and understand what waves are.

Focus Questions:

• What are waves?

• What is amplitude?

• What is wavelength?

• How do waves help us hear sound?
