Mississippi Science P.8.6

P.8.6 is a cluster heading. These are the individual standards under it.

• P.8.6.1

  Interpret the characteristics and behaviors of sound and light waves to determine the relationship between matter and energy; determine the medium for transmiss...

• P.8.6.2

  Investigate research-based mechanisms for capturing and converting wave energy (frequency, amplitude, wavelength, and speed) into electrical energy.

• P.8.6.3

  Conduct simple investigations about the performance of waves to describe their behavior (e.g., refraction, reflection, transmission, and absorption) as they int...

• P.8.6.4

  Use scientific processes to plan and conduct controlled investigations to conclude sound is a wave phenomenon that is characterized by amplitude and frequency.

• P.8.6.5

  Conduct scientific investigations that describe the behavior of sound when resonance changes (e.g., waves in a stretched string and design of musical instrument...

• P.8.6.6

  Obtain and evaluate scientific information to explain the relationship between seeing color and the transmission, absorption, or reflection of light waves by va...

01

What Students Need to Do

Students compare sound and light by amplitude, frequency, wavelength, and speed. They test how waves behave when they meet different materials and how changing a stretched string affects its sound. They explain how a device can turn wave energy into electrical energy.

02

What Mastery Looks Like

Students link louder sounds to greater amplitude and higher pitch to greater frequency. They change one variable in a string test and explain why sound needs matter to travel, but light can cross space. They predict what a mirror, lens, or colored filter does to light and explain how a microphone makes an electrical signal.

03

Common Misconceptions

Students may think louder sound has a higher pitch. Some think sound travels through empty space or that light needs air. Others think a red filter creates red light rather than transmitting red light and absorbing other colors.

How to Assess It

Exit ticket: A student plucks a rubber band beside a phone microphone and shines white light through red film. Ask what changes when the band is plucked harder, why the microphone needs air, and why the film looks red.

1. 01

   Stretch a rubber band over a tissue box, change its tension, and use a phone tuner app to record each pitch.

2. 02

   Ask students to write two sentences explaining why sunlight reaches Earth through space but sound from the Sun does not.

3. 03

   Sort cards showing a prism, mirror, clear window, and black shirt into refraction, reflection, transmission, and absorption.

4. 04

   Give pairs a microphone diagram and have them trace how sound vibrations become the electrical signal in a phone call.

• PHS.6

  Students will explore the characteristics of waves.

• P.4.6C

  Students will demonstrate an understanding of the properties of sound as a form of energy.

• P.1.6B

  Students will demonstrate an understanding of sound.

• PHY.4

  Students will investigate and explore wave properties.
