HS-PS4-5: Communicate technical information about devices that transmit and capture information and energy.

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.]


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 device (CCD) used in digital camera
  • Photocells
  • Photomultipliers
  • Gold-leaf electroscope
  • Image intensifier (night vision goggles)

  • Radio
  • Electron microscope
  • Thermographic camera (infrared camera)
  • Wireless power transfer (farfield or radiative techniques)
  • Radar
  • Sonar
  • Wifi
  • Mobile Phone
  • Seismic reflection imaging
  • Cameras

Radioactive Dinner Plate

Image
This video shows two plates being measured for emission of radiation. The orange Fiesta plate was made using a glaze which contains uranium oxide. Fiesta dinnerware was produced by the Homer Laughlin China Company of West Virginia. Prior to World War II the glazes used natural uranium.  This practice stopped during the war when the US government seized the company's stock of uranium for the Manhattan Project.  In the late 1950's the Atomic Energy Commission relaxed restrictions on uranium and production practices switched to using depleted uranium to produce the red-orange glaze. The US Environmental Protection Agency recommends that dinnerware produced with uranium glaze should not be used for food, drink or food storage.

The Effect of Concentration on the Rate of a Chemical Reaction

Image
This video shows a classic lab examining the effect of concentration of reactants on the rate of a chemical reaction.  This video supports NGSS HS-PS1-5 . In this experiment solutions of sodium thiosulfate and hydrochloric acid are combined in a beaker.  The reaction produces a precipitate which eventually makes the liquid turn cloudy.  The reaction beaker is placed over a piece of paper with a letter "X" printed on it.  The reaction is said to have gone to completion when the "X" can no longer be seen through the liquid in the beaker. I have used this video as a warm up or as a flipped lesson which has students make observations, record data about the reaction time for the trials, create a graph and form a conclusion about the effect concentration has on the speed of a chemical reaction. This lab was originally published by Flinn Scientific as a Chem Fax!  Use this link to see the full description of the experiment.
