History's Thermometers
Ancient coral beds give scientists clues to past ocean temperatures in much the same way that tree rings indicate historical weather conditions. High school scientists examine coral oxygen isotope ratios and plot the data as a function...
NOAA
History's Thermometers
How is sea coral like a thermometer? Part three of a six-part series from NOAA describes how oceanographers can use coral growth to estimate water temperature over time. Life science pupils manipulate data to determine the age of corals...
Curated OER
Dating Sedimentary Strata
Students investigate how the age of sedimentary strata is determined. In this sedimentary strata instructional activity, students work through problems that show that geological history covers millions of years. They distinguish between...

The History of Life
In this history of life worksheet, students complete a crossword puzzle by figuring out the vocabulary words associated with the 11 clues given. Then students review how paleontologists use fossils to learn more about past living things...

Assessment & Evaluation
Seventh graders study elapsed time, radioactive decay and half-life. In this time machine lesson students complete several activities and view a presentation.

Plate Tectonics I
Young geologists get a glimpse beneath the earth's surface in this plate tectonics investigation. After first learning about the different layers of the earth and the constant movement of its plates, young geologists work in small groups...

A Scale of the Earth
Students create a scale model of the different eras, periods, and epochs of Earth's 4.6 billion year history. In addition to different time periods, other major events will also be added to the model from fabricated radioactive decay...
Curated OER
Rocks, Minerals, and Erosion
Young scholars identify and describe rocks that contain records of the earth's history and explain how they were formed. They formulate questions about and identify needs and problems related to objects and events in the environment, and...
Curated OER
work in pairs for the activities of this lesson which include researching and identifying butterflies, writing, and a brief oral presentation.
Students explore the concepts of rdioactive decay and dating. They generate a radioactive decay table, use their data to plot a decay graph, develop the concept of half-life, and then use the graph to find the age of a mummified seal in...
Curated OER
Impact Craters
Students investigate the factors affecting the size of a crater. In this space science activity, students collect data from the activity and graph them. They explain how velocity of impact relate to crater size.
Curated OER
Developing a Local Stratigraphy
Students examine rock strata for the distribution, deposition, and age of sedimentary rock. They describe rock types in a variety of outcrops and construct a regional stratigraphy.
Curated OER
Crater Creation
Students examine the Oregon state quarter and discuss how Crater Lake was formed-geologically and according to Native American legend. They practice making predictions and identifying the beginning, middle, and end of a story.

Alphas, Betas and Gammas Oh, My!
Referring to the periodic table of elements, nuclear physics learners determine the resulting elements of alpha and beta decay. Answers are given in atomic notation, showing the atomic symbol, mass, atomic number, and emission particles....

Exploring Potential Human Impacts
Arctic sea ice reflects 80 percent of sunlight, striking it back into space; with sea ice melting, the world's oceans become warmer, which furthers global warming. These activities explore how humans are impacting ecosystems around the...
Curated OER
Crater Creation
After looking at the back of a quarter featuring Oregon terrain, learners distinguish between fiction and non-fiction and identify the beginning, middle and end of a story. First, they listen to legends that describe the creation of...
