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 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 8.1.6
OVERVIEW: Over the next several days the students will be developing and using models to reinforce the idea that in a chemical reaction atoms/matter are conserved and not created nor destroyed. We will be teaching the students about the Law of Conservation of Matter or also known as the law of conservation of mass. It states that for any closed system (no transferring of energy) the mass or matter of the system must remain constant over time, hence the quantity of mass is “conserved”. The only way to change the mass of the system would be to add or remove it.
Students experience a phenomenon in which matter appears to be lost when a chemical reaction takes place. They will measure the mass of the reactants, perform the reaction, and measure the mass of the products. Students will ask questions about what they experienced. Students then compare the masses of the reactants and products of several chemical reactions in episode 2. They will decide if any mass was lost and if so, what might have happened to it. Students are introduced to the Law of Conservation of Mass (matter). In this episode three students will review the Law of Conservation of Mass and learn how to recognize if chemical equations follow this law. They will review how to write molecular formulas and will learn how to write a full chemical equation, including how to show the number of molecules involved. In episode four, students will create a model demonstrating that in a chemical reaction, matter is conserved, or the same atoms rearrange to form new molecules, following the Law of Conservation of Mass.
Assessment: The assessment for this standard is the model that the students create in episode 4 to demonstrate the law of conservation of mass. As part of that they should demonstrate that they understand how to read a chemical equation and can recognize if the follows the law of conservation of mass as it is written (if it is balanced).
Episode 1
​
Question
What happens to mass of reactants during a chemical reaction?
Snapshot
Students experience a phenomenon in which matter appears to be lost when a chemical reaction takes place. They will measure the mass of the reactants, perform the reaction, and measure the mass of the products. Students will ask questions about what they experienced.
Conceptual Understandings
Sometimes it appears that matter is lost during chemical reactions.
Is mass always lost during a chemical reaction?
Conceptual Understandings
Students will discover that according to the Law of Conservation of Mass, the mass of reactants should equal the mass of the products of a chemical reaction. In a chemical reaction bonds between atoms break apart and rearrange to create new substances.
What do balanced equations look like with the law of conservation of mass?
Snapshot
Students will compare the masses of the reactants and products of several chemical reactions. They will decide if any mass was lost and if so, what might have happened to it.
Students are introduced to the Law of Conservation of Mass (matter).
Episode 2
​
Question
What happens to the atoms when a chemical reaction occurs?
Episode 3
​
Question
What do balanced equations look like with the law of conservation of mass? How do we balance equations?
Snapshot
Students will play the PhET Balancing Equations game to learn how and what balanced equations look like.
Conceptual Understandings
Students will discover that balanced chemical equations demonstrate the law of conservation of mass.
Can we create a model to illustrate the Law of Conservation of Mass?

Question
Can we create a model to illustrate the Law of Conservation of Mass?
Snapshot
In this episode, students will create a model demonstrating that in a chemical reaction, matter is conserved, or the same atoms rearrange to form new molecules, following the Law of Conservation of Mass.
Conceptual Understandings
The final assessment for this standard is the model that students create demonstrating the Law of Conservation of Mass during the final episode.
