Waves, Energy, and Information Suggested science learning activities for SPS students during the COVID-19 school closure.
Seattle Public Schools is committed to making its online information accessible and usable to all people, regardless of ability or technology. Meeting web accessibility guidelines and standards is an ongoing process that we are consistently working to improve.
While Seattle Public Schools endeavors to only post documents optimized for accessibility, due to the nature and complexity of some documents, an accessible version of the document may not be available. In these limited circumstances, the District will provide equally effective alternate access.
Due to the COVID-19 closure, teachers were asked to provide packets of home activities. This is not intended to take the place of regular classroom instruction but will help supplement student learning and provide opportunities for student learning while they are absent from school. Assignments are not required or graded. Because of the unprecedented nature of this health crisis and the District’s swift closure, some home activities may not be accessible.

Answer the following questions about how sound travels between a mother dolphin and her calf. Base your responses on what you have studied about waves in Chapter 1. Use the Sound Diagram on the next page for Questions 1–3.
1. On your Sound Diagram, label the source and label the listener.
2. On your Sound Diagram, label what is traveling and draw an arrow to show the direction it is traveling.
3. On your Sound Diagram, label what is moving a little but not traveling.
4. Explain how the sound gets from the mother dolphin to her calf. Make sure to include what is moving a little, and what is traveling far.
Waves, Energy, and Information —Lesson 1.5 (optional)
Chapter 1: Check Your Understanding
This is a chance for you to reflect on your learning so far. This is not a test. Be open and truthful when you respond.
Scientists investigate in order to explain how or why something happens. Am I getting closer to figuring out how a mother dolphin can communicate with her calf underwater?

I understand what travels far in a sound waveand what moves only a little. _____ Yes _____ Not yet
I understand how sound energy travels throughthe particles of a material. _____ Yes _____ Not yet
I understand why some dolphin sounds are different from other dolphin sounds. _____ Yes _____ Not yet
I understand that science explanations describehow or why something happens. _____ Yes _____ Not yet
