Students identify and analyze how the geologic time scale was developed by investigating 11 periods of time and the vast expanse of time of the Earth's existence. They study their period, determine the important factors indicative to...

Can you imagine Washington DC and London as close neighbors occupying the same continent? Learners will be fascinated as they step back in time and discover the evolution of the earth's continents and oceans from 4.5 billion...

Learners create a simple tool to visualize geologic time. They create knots to represent the K/T, P/T and Precambrian boundaries in a 4.6 meter string with each millimeter representing one million years. They then refer back to this...

Young geologists attempt to predict the appearnace of a geode's internal structure based on how it looks from the outside, its mass, and its physical characteristics. In this geologly lesson, learners use scientific equipment to collect...

Take young geologists on an exploration of the collection of rocks and minerals that we call Earth with an upper-elementary science lesson. Through a series of class discussion and hands-on investigations, young scholars learn about...

Seventh graders study the law of superposition by creating models of fossils in layers of rock. They examine how fossils are usually found in sedimentary rock which leads to the study of geologic history in those rocks.

Seventh graders model radioactive decay using pennies, collect data from their model, apply scientific visualization techniques to their data and create animated models explaining the concept of radioactive half-life.

Underclassmen create a cone-shaped landform and then draw a contour map for it. Then they examine a quadrangle (which was easily located with an online search), and relate it to what they experienced. The accompanying worksheet is...

Students use topographic maps to identify parts of rivers. In addition, they discover gradient and predict changes in the channels caused by variations in water flow. Other activities include sketching a river model with a new channel...

Seventh graders study the theory of plate tectonics.  In this activity lesson students complete an activity to determine how seafloor spreading and volcanoes contribute to solving the plate tectonics...
