Vocabulary
- Paleoclimate: The climate of the geological past.
- Stratigraphy: The study of rock layers (strata).
- Mold and Cast: Types of fossil formation where an impression is left in sediment.
- Trace Fossils: Fossils that provide evidence of the activity of organisms.
- Biostratigraphy: Using fossil organisms to date and correlate rock layers.
- Index Fossil: A fossil used to define and identify a particular time period.
- Carbon Dating: A method for determining the age of ancient organic material.
- Fossil Record: The totality of fossilized artifacts and their placement.
- Sedimentary Rock: Rock formed by the accumulation of sediment.
- Geologic Timeline: A representation of the sequence of events in Earth’s history.
Utah Seed Standards
- SEEd.7.4.4: Analyze fossils to provide evidence of the history of life on Earth.
Activities
- Fossil Dig Simulation: Use clay to create and find fossils.
- VR Activity (Victory XR): Explore a virtual fossil dig site.
- Quiz: Fill in the blanks for key fossil terms.
Lesson 4: Plate Tectonics and Earthquakes 🌋
Objectives
- Explore the theory of plate tectonics.
- Understand how plate movements cause earthquakes.
Vocabulary
- Tectonic Plates: Large pieces of the Earth’s crust that float on the mantle.
- Fault Line: A crack in the Earth's crust where earthquakes often occur.
- Seismic Waves: Waves of energy caused by earthquakes.
- Magnitude: The size or energy of an earthquake.
- Epicenter: The point on the Earth’s surface directly above the earthquake's point of origin.
- Subduction Zone: An area where one tectonic plate slides beneath another.
- Transform Boundary: Where two plates slide past each other.
- Convergent Boundary: Where two plates collide.
- Divergent Boundary: Where two plates move apart.
- Aftershock: Smaller earthquakes that follow a larger quake.
Utah Seed Standards
- SEEd.7.4.5: Use data to predict the effects of tectonic plate interactions.
Activities
- Create a Tectonic Map: Students work in groups to illustrate tectonic boundaries.
- VR Activity (Engage): Experience tectonic plate movements.
- Assessment: Group presentations on tectonic activities.
Lesson 5: Human Impact and Climate Change 🌍
Objectives
- Recognize how human activities accelerate geological changes.
- Explore the concept and impact of climate change.
Vocabulary
- Anthropogenic: Resulting from the influence of human beings on nature.
- Climate Change: Significant and lasting change in weather patterns.
- Deforestation: The clearing or thinning of forests.
- Pollution: Contamination of air, water, or soil.
- Sustainability: The ability to maintain ecological balance.
