HS-PS4-5
The standard
Communicate technical information about how some technological devices use the principles of wave behavior and wave interactions with matter to transmit and capture information and energy.
Next Generation Science Standards
What this standard means
Students need to explain, in words and simple diagrams, how devices use waves to send, receive, or capture information and energy. They should connect wave behaviors like reflection, absorption, transmission, and interference to real technologies such as solar cells, cell phones, Wi-Fi, cameras, fiber optics, and medical imaging.
Mastery looks like a clear technical explanation that links the device, the type of wave, the wave interaction, and the outcome. Students often get stuck using vague phrases like “waves make it work,” mixing up energy and information, or describing the device without explaining the wave behavior behind it.
Ways to teach it
- Have students label a diagram of a solar cell, phone tower, or ultrasound probe with the wave type, interaction, and output.
- Ask students to write: How does one device use waves to capture or transmit information without moving matter from place to place?
- Give a three-question exit ticket asking students to match a device, wave behavior, and purpose, then explain one match in a sentence.
- Show a barcode scanner, phone camera, or wireless router and ask students to trace how waves carry or capture useful information.
