Curated OER
Candy Quakes
Eighth graders, using a candy bar, gum, and Twizzlers, demonstrate the effects of deformational forces on the earth's crust. They examine the processes of rock and fossil formation.
Curated OER
Erosion
Students study various types of erosion. The purpose of these activities is to increase students awareness to the point where they can make intelligent decisions on proper land use.
Curated OER
Plate Tectonics
Students identify the three layers of the earth: core, mantle and crust. They demonstrate knowledge of the concepts of convergent and divergent motions of the earth and an understanding of plate tectonics.
Curated OER
Earthquakes And Volcanoes
Students investigate the concept of plate tectonics through focusing a research study upon the occurrence of earthquakes and volcanic eruptions. They find information that is used for class discussion. Students complete a mapping of...
Curated OER
Rock Layers
Students interpret a rock core sample from a clay model. In small groups, they layer modeling clay in a plastic container using coarse-grained spices sprinkled in to represent fossils. They switch containers with another group and remove...
Curated OER
Carving Mountains
Students explore geography by participating in an illustration activity. In this land-form instructional activity, students define vocabulary terms associated with glaciers and forests. Students utilize pens, cardboard and pottery clay...
Curated OER
Candy Quakes
Eighth graders use candy to show the effects of deformation forces on the earth's crust. In this rock and fossil formation instructional activity students construct models and simulations to describe and explain natural phenomena.
Curated OER
Earthquakes and Seismic Waves
Students investigate the Richter scale and seismology in a teacher-led lab in which they are introduced to the concept of seismic waves and epicenter location. They further investigate the inner workings of a seismograph and practice...
Curated OER
Mesozoic Era in Arkansas
Eighth graders study the geology of Arkansas from 225 million years ago to 65 million years ago. They discover they types of strata laid down by the Gulf of Mexico. They examine the economic importance to the community.
Curated OER
Law of Superposition
Students identify the law of superposition and it states that beds of rock in a series are laid down with the oldest at the bottom and younger layers on the top. They construct a legen for a block diagram and construct a block diagram...
Curated OER
Core
Eighth graders examine conditions that can lead to the formations found and correlate the layers. In this rock layers lesson students complete an activity that allows students to take their own "core sample".
