Students will explore how human population growth, air pollution, agriculture, mining, water use, and other human activities have impacted the environment and the mark they will leave in the fossil record.
In this lesson, students will learn that ice formations on land will cause a rise in sea level when they melt, whereas ice formations on water will not cause a rise in sea level when they melt. They will also learn that ice is less dense than water, that ice displaces water equal to the mass of the ice, and they will practice some of the steps involved in a science investigation.
Students practice calculating Simpson's Index of Diversity using playing cards as "species." Then they will use the equation and a sample set of data to calculate Simpson's Index of Diversity for a representative sample. Students can also conduct their own studies to obtain data.
Students compare water quality at different points in a stream or river. They will use freshwater invertebrates to obtain and compare biotic index scores for different sampling stations.
Students willl create and review the parts and purposes of an aquifer.
This online article describes aquifers as a source of freshwater located below the surface of the earth. The movement of water into and out of aquifers is also discussed.
In this unit students should be able to describe multiple types of irresponsible fishing practices contributing to the collapse of currently fished seafood; identify sustainable seafood available in your community; and
make responsible seafood choices.

Much of the more than 30 million tons of asbestos used in the United States since 1900 is still present as insulation in offices and schools, as vinyl-asbestos flooring in homes, and in other common products. This book presents a comprehensive evaluation of the relation of these fibers to specific diseases and the extent of non-occupational risks associated with them. It covers sources of asbestiform fibers, properties of the fibers, and carcinogenic and fibrogenic risks they pose. The book may be read online, printed, or purchased from the site.
This article provides an overview of using rubrics as a method of assessment and discusses technological tools that facilitate the creation of rubrics.
Students learn about the composition of the atmosphere and how atmospheric conditions affect humans.
Students will learn about the structure and composition of the atmosphere. Students will also track weather conditions for four days. and relate their observations to atmospheric characteristics.

This site features Java Applet, QuickTime, and Flash animations that illustrate characteristics and functions of the atmosphere. They show how atmospheric temperature, pressure, and density change with respect to changing altitude, the way different kinds of radiation (x-ray, ultraviolet, visible, and infrared) act in various levels of the atmosphere (troposphere, stratosphere, mesosphere, and thermosphere/ionosphere), how oxygen gas and chlorofluorocarbons (CFCs) interact with ultraviolet radiation to create and deplete ozone, and the manner in which radiation is trapped in the atmosphere, causing the greenhouse effect and global warming. The animations can be paused and rewound to stress important points. These resources are suitable for use in lectures, labs, or other teaching activities.
This is a four-day unit focusing on the composition, properties, and structure of Earth's atmosphere. The lessons are embedded in a Google Slide presentation (http://bit.ly/AtmosphereCharacteristics) allowing teachers to modify the lessons to their needs. Formative and summative assessments are included in the form of warm-up and exit ticket questions and a summative project.
This resource discusses severe weather that can occur around the globe.
In this lesson, students will use Google Earth to explore global temperature changes. They will use Google Earth to determine how the temperature of the Earth has changed during a recent 50-58 year period. They will also explore, analyze, and interpret climate patterns of 13 different cities, and analyze differences between weather and climate patterns.
