Unit Storyline
Students likely have experiences with cellular phones, whether their own or family members’. Likely the phones are used for much more than just making calls and sending text messages. Throughout the chapter, students will apply principles of sound and light to cellular phones to begin to explore the basics of how phones work. These principles include the wave model of sound, both the wave and photon model of light.

Crosscutting Concepts To help students Think Like a Scientists, they need to know how to question and gather evidence in order to refine and revise what they know and understand. The information below provides suggestions for connecting Thinking Maps to our science concepts. The thinking maps listed are general connections and should not be seen as the only maps that could be used. Using Thinking Maps in Science
Cause and Effect
Critical Questions: What evidence is there for this cause and effect relationship? What are other possible causes? How is this relationship similar to others? How does changing one event affect the results?
Systems and System Models
Critical Questions: What parts and sub-systems make up this system? What interactions and processes involve this system? How is this system alike or different from others? What are the effects of modifying one part of the system?
Energy and Matter
Critical Questions: How are energy and matter related in this system? Where does the energy for this system come from? Go?
Stability and Change
Critical Questions: What causes change in this system? Stability? Is the stability static or dynamic? What are possible catalysts for changing the stability?
Anchor Phenomenon
PEER Anchoring Phenomena & Storylines
Phenomenon Option 1 How do scientific models help us prepare for natural disasters?
In February of 2023, a powerful earthquake struck the countries of Turkiye and Syria, causing widespread damage and loss of life. Earthquakes are a more common event than most people might think. Most of them are barely noticeable, but powerful earthquakes are among the most dramatic and deadly natural disaster that happen on Earth. Scientist use models to understand how earthquakes are caused and how they travel. By studying earthquakes and seismic waves, scientist can also make claims about the Earth itself and what is inside it. How do you think scientist compare earthquakes with each other? How can scientists use data about seismic waves to better predict and prepare for earthquakes?
Phenomenon Option 2 How do waves help us communicate?
Students likely have experiences with cellular phones, whether their own or family members’. Likely the phones are used for much more than just making calls and sending text messages. Throughout the chapter, students will apply principles of sound and light to cellular phones to begin to explore the basics of how phones work. These principles include the wave model of sound, both the wave and photon model of light.

Local Colorado Phenomena Connections
Exploring local Colorado phenomena can offer students relatable and engaging examples of waves in action. Here are a few ideas:
Echoes in the Mountains: The Rockies provide an excellent setting to discuss sound waves and echoes. You can explore how sound waves travel, reflect off surfaces, and create echoes in mountain landscapes.
Colorado River Rapids: Use the rapids to explain water waves. Discuss how waves are formed, their characteristics, and how they interact with obstacles in the river.
Sunlight and the Continental Divide: The Continental Divide can be used to explore light waves. Discuss how sunlight is diffracted and refracted when it passes over the mountain range, impacting weather patterns and creating phenomena like rainbows.
Wind Patterns in the Great Plains: Discuss how wind waves form on the plains, explaining concepts like wave speed, amplitude, and frequency.
