Pupils make small cuts (fracture nuclei) in processed cheese food and then apply stresses perpendicular or parallel to the cuts to see how fractures grow. They make predictions before each experiment and explain their results to the rest...

Students apply the scientific method to identify rocks from glacial deposits, hypothesize how they got there and then test their hypothesis. They are given the experience of active, hands-on inquiry.

Twelfth graders use this game to find minerals given rocks and outcrops in a plausible (but not real) geologic setting. They play without outside encouragement for hours as the world is fun to explore and the scoring system encourages...

Students examine how to use GIS software to analyze patterns of groundwater flow. Seepage lake elevation data from the Sand Hills of Nebraska is used to construct a water table map and flow net using Esri's Arc Map software.

Students use an interactive online mass balance model to observe levels of chlorofluorocarbons over the past few years. Students evaluate the influence protocol emissions will have on the future levels of CFCs.

Students play an online strategy game working with a limited budget. They collect and interpret seismic data to search for oil traps, file environmental impact statements before drilling and use drill logs to determine when to start...

Students compare carbon dioxide (CO2) data from the Mauna Loa Observatory , Barrow (Alaska) , and the South Pole over the past 40 years to help them better understand what controls atmospheric (CO2).

Twelfth graders explore the Earth's radiation budget using Earth radiation Budget Experiment (ERBE) data archived at the IRI/LDEO Climate Data Library. They use photometers and light sources to work through several hands-on activities...

Pupils watch a demonstration using a Slinky during a lecture on basic wave properties. Properties addressed in the demo include wave speed, wave length, amplitude, period, and frequency.

Young scholars discuss the importance of identifying the main idea in reading selections. After reading newspaper articles related to nutrition, students identify the main idea of the selection and three supporting details. A reading...

Learners work in groups, plotting carbon dioxide concentrations over time on overheads and estimating the rate of change over five years. Stacked together, the overheads for the whole class show an increase on carbon dioxide over five...

In this questions and answers worksheet, students read 25 answers and write an appropriate question that could go with each one.

Young scholars develop a sense of geologic ("deep") time and the ways in which Earth scientists construct the geologic time scale. They study he major events that shaped Earth, including the origin and evolution of its lithosphere,...

Learners investigate arctic geology and hydrology as well as tundra ecology as they consider options for sewage treatment. Public safety, environmental impact, and issues of construction and engineering be explored.

Students use a microcomputer connected to a conductivity probe to measure the total dissolved solids in local area water samples. Students then compare their measurements with others in their class as well as other standard measurements.

In this verb worksheet, students read about the verb "BE." Worksheet is informational only, and covers explanations, examples, making questions and using negatives.

Students reflect on the fairness of rating movies, television, radio, books, magazines, Web sites and other media. They submit their own entries for a media rating guide.
