Sound Waves and Light Waves 

Grade Level: 1st

Subject: Science

Time Frame: 4 weeks (quarter 2)

​

Essential Questions

 

- what is sound and how does it travel?

- what causes different sounds?

- can we see more with or without light?

- what happens when an object is in the light path?

- what is a shadow and what causes a shadow?

- what is the difference between transparent, translucent, opaque and reflective surfaces?

- how does light react to different surfaces?

- what is communication?

- how do we use lights and sound to communicate?

- what types of devices do we use to communicate?

 

 

By the end of the unit, students will know:

 

- vibrations cause sounds

- sound can make objects vibrate

- we need light to see objects around us

- light can pass through transparent objects

- some light can pass through opaque objects

- light bounces off of reflective surfaces

- shadows are caused by opaque objects blocking the light source

- we use lights and sound to communicate

- we use a variety of devices to communicate

 

​

By the end of the unit, students will be able to:

 

- explain how sound is created

- explain what causes different sounds

- explain that we need a light source in order to see objects around us

- define and explain the differences between opaque, transparent, translucent, and reflection

- explain what causes shadows

- identify different ways we use lights and sound to communicate

- explain why it is important to communicate in different ways

- identify different devices we use to communicate

​
