STC-Middle School™, STC3 Edition: Earth's Dynamic Systems 5-Class Unit Kit

(in stock)


Grades 6–8. Unit Driving Question: How do the dynamic systems of Earth change its surface?
Unit Highlights—How did that aquatic fossil end up on the top of that mountain? In this unit's 12 lessons, students learn about gradual processes (erosion, deposition, plate motion, and fossilization) and catastrophic events (earthquakes, volcanoes) and how they contribute to changes on the earth's surface. Students track the transfer of energy, build models, and investigate mineral resources. Students conclude the unit with research on preparedness for catastrophic events. Are we ready for "The Big One"?

Earth's Dynamic Systems addresses the performance expectations, and attendant science and engineering practices and crosscutting concepts, deemed appropriate for grades 6 through 8 by the Next Generation Science Standards® (NGSS). It helps students develop a better understanding of geologic systems, how those systems change over time, and how engineering, technology, and applications of science are connected to each other and to students' daily lives.

Each lesson in this unit builds on the skills and concepts presented in previous lessons. As students progress through the unit, they take increasing responsibility for their own learning. Eventually, students plan and conduct their own procedures and analyze the results they obtain. Therefore, the unit should be taught in its entirety; it should not be used as a sourcebook of occasional experiments.

To structure and scaffold the development of students' knowledge, skills, and cognitive reasoning, this unit includes three primary lesson types: pre-assessment, skills and knowledge building, and assessment. The pre-assessment lesson allows educators to assess students' preconceptions, misconceptions, and skills. Skills and knowledge building lessons provide multiple opportunities for students to grow and learn through formative assessment. The assessment lesson includes both performance and written assessment activities that function together as a summative assessment of student learning.

This 5-Class Unit Kit comes with a Teacher Edition, teacher access to Carolinascienceonline.com, 16 reusable hardbound Student Guides (item #513503), student eBook access, and the materials needed for a teacher to teach up to 5 classes of 32 students per day.

Lesson Summaries
Lesson 1: Pre-Assessment

Focus Question: What do you know about geologic processes?
Students are introduced to two geologic events, the eruption of Krakatau in 1883 and the discovery of the Burgess Shale in 1909, through primary source documents and images. They consider these events, predict the way they may have occurred, and develop questions to explore about these events during the unit.
Lesson 2: When the Earth Shakes
Focus Question: Why are some structures damaged when Earth shakes?
Students observe videos of earthquakes and are introduced to shake tables as a way to model earthquakes. They design and conduct an experiment to investigate the effect of design variables on the way model buildings respond to shaking. Students use experimental data to describe conditions for areas with the greatest and least risk for future earthquake damage. Students then use iterative testing and modification to design a model of an earthquake-resistant house.
Lesson 3: Analyzing Earthquake Data
Focus Question: How can we collect data about earthquakes?
Students explore how data pertaining to earthquakes can be collected and analyzed. They explore wave motion, use model seismographs to collect simulated earthquake data, analyze seismogram readings, and use earthquake data to locate the epicenter of a quake. Through these investigations, students come to understand how earthquake data can show patterns that help in the prediction of future quakes.
Lesson 4: Investigating Plate Movement
Focus Question: How do changes in the lithosphere affect Earth's surface?
Students plot earthquake data to investigate patterns caused by earthquakes. They also examine the structure of Earth's interior to gain an understanding of the dynamic nature of Earth. Using models, students also simulate the movement of tectonic plates and examine the cause and effect of plate movements along faults.
Lesson 5: Cycling Matter and Energy
Focus Question: How do heat and pressure impact geologic features?
Students model the rock cycle and investigate the role of heat and pressure in cycling matter and energy. They also examine rock samples and use observational data to engage in an argument from evidence about the formation of each sample.
Lesson 6: Volcanoes: Building Up
Focus Question: How are volcanoes formed?
Students gain an understanding of how volcanoes are formed by modeling the movement of magma through Earth's surface. They then examine information pertaining to different types of volcanoes and gain an understanding of the relationship between earthquakes and volcanoes.

Lesson 7: Volcanoes: Eruption
Focus Question: How do volcanoes change Earth's surface?
Students conduct investigations to gain an understanding of how volcanoes contribute to the modification and creation of landforms. Students then revisit the Krakatau event and construct an explanation for the phenomenon, which involves changes at Earth's surface. Students make predictions for how surface features will continue to change in the future as geoscience processes continue to occur.
Lesson 8: Changing Earth's Surface
Focus Question: How have geoscience processes changed Earth's surface?
Students model several different geoscience processes to gain an understanding of their effect on Earth's surface. They research a real-world example of a process they modeled and present their findings. Students then revisit the Burgess Shale event and construct an explanation for rock deformation.
Lesson 9: Analyzing the Fossil Record
Focus Question: What do fossils and layers of sediment tell us about Earth's past?
Students investigate how fossils are formed and what they can tell us about the planet's history and the organisms that they represent. Through modeling and simulations, students examine the role of fossils in explaining the geologic events of the past. Students also use fossils to analyze and interpret patterns related to existence, diversity, anatomical structures, and extinction of organisms.
Lesson 10: Distribution of Resources on Earth
Focus Question: How do geoscience processes impact the distribution of resources on Earth?
Students map the locations of a specific mineral resource to reveal its uneven distribution and construct a scientific explanation. They use a model to simulate drilling for a natural resource and calculate the cost of the simulated exploration. Students also conduct research related to the mineral, energy, and groundwater resources of Earth and present their findings to the class.
Lesson 11: Evidence of a Dynamic Earth
Focus Question: What evidence suggests that Earth is a dynamic geological system?
Students again revisit Burgess Shale fossils and construct an explanation for an aquatic fossil being found well above sea level. Students will describe an appropriate timescale for the time since the fossil was underwater and the rate of elevation increase. Students will also analyze and interpret data related to the distribution of fossils and rocks, continental landforms, and features on the seafloor as evidence for plate motion in Earth's past.
Lesson 12: Assessment: Earth's Dynamic Systems
Focus Question: How can we use knowledge of Earth's dynamic systems to understand the past and prepare for the future?
The unit concludes with a two-part assessment. The first part is a Performance Assessment, in which students, acting as scientists, prepare and present proposals for mitigating the effects of future geodynamic events. Students also evaluate proposals from other groups and make recommendations for which proposals should receive funds. In the second part, students complete a Written Assessment that covers the performance expectations, disciplinary core ideas, crosscutting concepts, and science and engineering practices addressed in this unit.
