5.1 Strand
Earth’s major systems are the geosphere (solid and molten rock, soil, and sediments), the hydrosphere (water and ice), the atmosphere (air), and the biosphere (living things, including humans). Within these systems, the location of Earth’s land and water can be described. Also, these systems interact in multiple ways. Weathering and erosion are examples of interactions between Earth’s systems. Some interactions cause landslides, earthquakes, and volcanic eruptions that impact humans and other organisms. Humans cannot eliminate natural hazards, but solutions can be designed to reduce their impact.
Standard(s) 5.1.1: Analyze and interpret data to describe patterns of Earth’s features. Emphasize most earthquakes and volcanoes occur in bands that are often along the boundaries between continents and oceans while major mountain chains may be found inside continents or near their edges. Examples of data could include maps showing locations of mountains on continents and the ocean floor or the locations of volcanoes and earthquakes. (ESS2.B)
Practices
Analyzing and Interpreting Data Analyzing data in 3–5 builds on K–2 experiences and progresses to introducing quantitative approaches to collecting data and conducting multiple trials of qualitative observations. When possible and feasible, digital tools should be used.
-
Analyze and interpret data to make sense of phenomena using logical reasoning.
Disciplinary Core Ideas
ESS2.B: Plate Tectonics and Large-Scale System Interactions
The locations of mountain ranges, deep ocean trenches, ocean floor structures, earthquakes, and volcanoes occur in patterns. Most earthquakes and volcanoes occur in bands that are often along the boundaries between continents and oceans. Major mountain chains form inside continents or near their edges. Maps can help locate the different land and water features areas of Earth.

Patterns
Patterns can be used as evidence to support an explanation.
Storyline Narrative
To begin this storyline students will investigate the phenomenon, a volcano rapidly formed in a field in Paricutin. Students will obtain information about a volcano that grew in a field in Paricutin, Mexico over the course of 9 years, destroying the village.
Then students will obtain information about other North American examples of volcano and earthquake activity and mountain ranges to analyze patterns in the data. They will look at volcanoes in the area of Paricutin to understand and reason that the occurrence of that volcano was part of a pattern rather than a random act. From there, students will look at examples and nonexamples of volcanoes, earthquakes, and mountain ranges to further analyze and interpret data to find patterns of Earth’s features. Finally, when given a map with known volcano and/or earthquake occurrences, students identify which location is more likely to have the next occurrence and support their answer using the data from their investigations?

Storyline Narrative 8.2.6
Storyline Narrative:
In this storyline, students will obtain and evaluate information about the structure and function of analog and digital signals in order to communicate a reasoned argument to support the claim that digital signals are a more reliable means of communication than analog signals.
Students will engage in obtaining and evaluating information, first to define and describe a signal. Then they will be ready to explore the characteristics of analog and digital audio signals. After explaining the similarities and differences between these two types of signals, especially in terms of structure and function, they will be able to sort examples of objects and technologies that use them.
Students will then be ready to elaborate on what they have learned by obtaining, evaluating and communicating information about one means of communication. Lastly, student proficiency will be evaluated by a performance assessment: writing a claim, evidence, and reasoning (CER) paragraph.
Conceptual Understandings
Signals communicate information from sender to receiver.
How do signals vary?
Snapshot
Students obtain information about signals using online resources. They evaluate the information in order to identify the structure and function of signals. Then they communicate their understanding of signals in writing.

How do signals vary?
Snapshot
Students observe a series of images that represent a signal. They look for patterns in the series of images and ask questions about the patterns they observe.Then they listen to the sound bits that correspond to the images and repeat the observe, identify patterns, ask questions (OPQ) process.
Conceptual Understandings
Signals may change during analog transmission due to interference.
What other characteristics do analog and digital signals have?
Conceptual Understandings
Signals have distinct waveforms or structures.
What are examples of things that store or transmit signals?
Snapshot
Students watch a video clip to obtain information about analog and digital signals. They compare and contrast the types of signal. Then they write and share statements about the structure and function of analog and/or digital signals.
Episode 3
Explain
What other characteristics do analog and digital signals have?
Episode 4
Elaborate
What are examples of things that store or transmit signals?
Snapshot
Students sort 20 objects/technologies that store or transmit signals into two groups and then ask questions about the objects, technologies, means of communication and signals.
Conceptual Understandings
One example is music. Mp3 files are digital. Vinyl records store analog signals.
How are digital signals more reliable than analog signals?
Conceptual Understandings
Digital encoding and transmission of information has advanced science in a variety of ways.
Snapshot
Students choose a means of communication to research, obtain and evaluate information about it and then communicate what they have learned.
