Science Learning Packet Grade 4, Week 6: 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. If you have difficulty accessing the material or have any questions, please contact your student’s teacher.

Science Learning PacketGrade 4, Week 6:

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.

If you have difficulty accessing the material or have any questions, please contact your student’s teacher.

Investigating Amplitude

1. Open the Custom Sound mode of the Sound Waves Sim.2. Press Play to play a sound, and while the sound is playing, use the

Amplitude slider to change the sound.3. Observe what happens as you change the sound. Use your eyes and ears

to make your observations.4. Use what you observed to answer the questions below.

The amplitude is __________ (larger/smaller) when the sound is louder.

The amplitude is __________ (larger/smaller) when the sound is quieter.

What happens to the waveform when you change the amplitude?

Analyzing Amplitude

1. Look at the Wave Printout below. Label the volume of the sound in each section of the waveform. You can use the following words as labels: loud, medium, quiet.

2. Open the Custom Sound mode of the Sound Waves Sim.3. Press Play to play a sound, and as the sound is playing, use the Amplitude

slider to try to make the Wave Printout match the one shown below. It may take a few tries!

4. Update your labels if needed.

Reading About Wavelength and Amplitude

1. Read the following sections of Patterns in Communication that contain information about both amplitude and wavelength:• Information That Travels as Waves (pages 6–7)• Treehopper Communication (pages 34–35)

2. As you read, don’t forget to look carefully at the diagrams and images as well as the text.

3. After reading, answer the following questions.

How are wavelength and pitch related?
