HS-PS4-5. 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.* [Clarification Statement: Examples could include solar cells capturing light and converting it to electricity; medical imaging; and communications technology.] HS-PS4-5. Evidence Statements This performance expectation has students communicating technical information about two devices using varying formats (textual, graphical, oral and mathematical are listed in NGSS evidence statements. I'm having my students research two devices (one that relies on the photoelectric effect, a second that depends on wave properties) and then create a screencast video using text, images and narration to teach their classmates about the device they selected. Devices that depend on the Photoelectric Effect: Photovoltaic cells (solar panels) Photocopiers Charge coupled devi
