ES 8-E-13
We are learning to describe how landforms are created through a combination of destructive (eg. weathering and erosion) and
constructive processes (eg. crustal deformation, volcanic eruptions, deposition of sediment)
We are looking for a description of destructive processes of
 Weathering and the two basic types of weathering.
o Chemical

Physical (mechanical)
We are learning to formulate and identify questions to connect science concepts and guide their investigations.
We are looking for students to:
 Identify the questions
 Make the connections between the concepts

ES- E-13
We are learning to describe how landforms are created through a combination of destructive (eg. weathering and erosion) and
constructive processes (eg. crustal deformation, volcanic eruptions, deposition of sediment)
We are looking for how these destructive processes of erosion occur:
 Mass movement.
 Landslides
 Mudslides
 Slump
 Creep
4
ES E-13
We are learning to describe how the constructive process of deposition of sediment creates landforms.
We are looking for how the following are created by deposition of sediment:
 deltas
 alluvial fans
 meanders
 oxbow lakes

ES 8-12
We are learning to explain the processes involved in the rock cycle that are directly related to thermal energy and forces in the mantle that
drive plate motion.
We are looking for an explanation of the processes in the rock cycle:
 Heat and pressure create metamorphic rock
 Melting, cooling and solidifying create igneous rock
6
ES 8-E-14
We are learning to explain how folding, faulting and uplifting contribute to the rearrangement of rock layers.
We are looking for an explanation of each of the following and how they contribute to the rearrangement of rock layers.
 Folding- rocks are rearranged by bending
 Faulting- rocks are rearranged by movement of faults
 Uplifting- rocks are rearranged by tectonic activity forcing them upward
LS 8-D-4
We are learning to explain that the diversity of species is developed over generations, as shown by the fossil record.
We are looking for how the fossil record shows the evolution of life on Earth:
 Animals which have become extinct
 Older rocks contain fossils of simpler organisms
 Younger rocks contain fossils of more complex organisms
 The activities of ancient animals
7
LS 8-D-5
We are learning to describe how organisms may become extinct if the environment changes as shown by the fossil record.
We are looking for how these environmental changes could cause mass extinction:
 Ice age
 Tectonic activities
 Floods
8
ES 8-E-9
We are learning to describe the structure of the Earth’s interior.
We are looking for a description of the characteristics of Earth’s interior:
 Crust, mantle, core
 Lithosphere, asthenosphere
9
ES-8-E-9
We are learning to describe how the Earth’s crust is divided into tectonic plates which ride on top of the slow moving currents of magma in
the mantle.
We are looking for how the following evidence supports plate movement (continental drift):
 Landforms
 Fossils
 Climate
10
ES 8-E-15
We are learning to explain how boundaries cause different landforms.
We are looking for the landforms created at:
 Divergent boundaries:
 Mid-ocean ridges
 Rift valleys
 Convergent Boundaries
 Mountain building
 Trenches
 Transform
 Off-set features
11
ES 8-E-10
We are learning to explain that most geological events result from plate motion.
We are looking for a explanation of features on the Earth’s surface created by plate tectonics:
 Mountain building
 Volcanic eruptions
 Hot Spots/Island arcs
 Faults/Earthquakes
12
SI 7-B-7
We are learning to use graphs, tables and charts.
ES 8-E-10
We are looking for use of graphics to study physical features and to make inferences about relationships between variables
 Density
 Heat transfer
.
We are learning to explain that most geological events (volcanic eruptions, mountain building) result from plate motion.
We are looking for use of maps to explain the plate movement as it relates to the location of mountain ranges, volcanoes, and rift valleys.

We are learning to illustrate how the three type of plate boundaries cause volcanoes (landform).
ES 8-E-15
We are looking for a graphic showing how the three types of boundaries create volcanoes:
 Divergent boundaries
 Convergent boundaries
 Transform boundaries
