Students learn about physical models of groundwater and how environmental engineers determine possible sites for drinking water wells. During the activity, students create their own groundwater well models using coffee cans and wire screening. They add red food coloring to their models to see how pollutants can migrate through the groundwater into a drinking water resource.

Our modern world uses many different materials, often complexly constructed and difficult to recycle. Students investigate the elements in a smartphone and innovations in cement and steel. They also consider the challenge of communicating about large and complex numbers. This guide an extension of the TILclimate episode "TIL about materials."

In this 7th grade humanities lesson, students prepare tortillas, pico de gallo, and tomatillo salsa after learning about the different agricultural techniques developed by the Mayan, Aztec and Inca civilizations.

This video segment adapted from Interactive NOVA profiles two scientists who were surprised in 1984 to discover a hole in our atmosphere's ozone layer as big as the United States.

Students learn about geotechnical engineers and their use of physical properties, such as soil density, to determine the ability of various soils to offer support to foundations. In an associated activity, students determine the bulk densities of soil samples, and assess their suitability to support foundations.

Soil and Water Conservation: An Annotated Bibliography highlights freely-available online resources covering various aspects of soil and water conservation, and is designed to be a resource for conservation students and practitioners. The thirteen chapters in the annotated bibliography are grouped into four sections, including History and Fundamentals, Conservation Practices, Conservation Implementation, and Careers. Types of cited resources include extension bulletins, USDA NRCS conservation practice standards, and other government reports and resources. Cited resources are generally concise, easily read, and meant for general audiences. Annotations and images are used to provide context for each resource. Many contributors made Soil and Water Conservation: An Annotated Bibliography possible through their assistance with technical edits, outline development, identifying resources, or writing annotations. Chapter authors are experts and practitioners of soil and water conservation, or students of soil and water conservation who worked under the supervision of the editor, Colby Moorberg. The annotated bibliography is used as the primary text for Kansas State University’s AGRON 635 – Soil and Water Conservation, which is taught by Moorberg.

Students will use images, U.S. Census Bureau data, and interactive maps to visualize and calculate arithmetic (population), agricultural, and physiological densities at local, regional, and national scales. They will also transfer their calculations to bar graphs.

In this lesson students investigate how the layers of a spacesuit protect an astronaut in space.

This course looks at all forms that energy exists. It explains how energy is used in: transport, agriculture, industry, commerce and households. It describes how energy is stored using storage systems such as: battery, flywheels, compressed air, chemical energy systems and pumped storage. This course explains the problem of depletion of energy resources. It describes the environmental damage associated with the use of fossil fuels, acid rains, dangers posed by leaded fuels, oil spills, gas leaks and explosions, water pollution caused by poorly managed coal mines, and air pollution. It describes the environmental damage associated with the use of fuelwood, uranium, hydro-power plants and wind. It also explains possible solutions to the energy-related problems.

Students complete three different activities to evaluate the energy consumption in a household and explore potential ways to reduce that consumption. The focus is on conservation and energy efficient electrical devices and appliances. The lesson reinforces the relationship between power and energy and associated measurements and calculations required to evaluate energy consumption. The lesson provides the students with more concrete information for completing their culminating unit assignment.

This unit delves into the fundamental science and historical contexts to help students explore the question "How can knowledge gained from the Manhattan Project and the Hanford Site contribute using nuclear technologies to positively impact humanity in the future?."Nuclear Chemistry is a great capstone unit for a standard high school chemistry course in that it is fantastic opportunity for students to explore the crossroads between scientific knowledge and the societal implications of new discoveries. Students will have the opportunity to Delve deep into the science standards while also connecting their learning to what it means for us as a global society.

The culmination of the Explore the Salish Sea Curriculum is improving the environment for wildlife and people in your own community. Students will review the science and traditional ecological knowledge-based recommendations they have made after each scientific investigation throughout the previous units, then choose one to put into action. Their choices will depend on available resources, time, and expertise available.

In this lesson, students find their location on a map using Latitude and Longitudinal coordinates. They determine where they should go to be rescued and how best to get there.

This series of 18 captioned images depict several weather and climate-related events such as flooding, drought, glacial retreat and wind erosion. The Climate Kids website is a NASA education resource featuring articles, videos, images and games focused on the science of climate change.

In this video adapted from Storyknife Productions, Alaska Native pilots share how they use traditional knowledge to read the landscape and predict the weather.

Prior to reaching households, water is exposed to a variety of treatments designed to render it fit for human consumption and use. One of the first treatment steps is the removal of suspended solids using chemical additives called flocculants. In this activity, students learn about two commonly used flocculants and clean water collected from a local pond or river. They experiment with flocculant, stirring and pH variables.

This activity allows children to explore the effects of oil spills on birds.

This activity identifies and explains the benefits of and threats to coral reef systems. Students read tutorials, describe the role of satellites, analyze oceanographic data and identify actions that can be undertaken to reduce or eliminate threats to coral reefs. As a culminating activity, students prepare a public education program.

The purpose of this resource is to familiarize students with modeling as it relates to remote sensing and digitized images. Students will use the symbolic map created in the beginning activity to produce a digitized image and begin to see why ground verification of satellite data is necessary.

This video demonstrates students measuring the transparency of water, a measure of water quality, using a Secchi disk or turbidity tube. Field measurements of water temperature are also shown. The resource includes a video and a written transcript, and is supported by the Water Transparency and Temperature Protocols in the GLOBE Teacher's Guide. This is one of seven videos on hydrology in the 24-part instructional video series describing scientific protocols used by GLOBE (Global Learning and Observation to Benefit the Environment), a worldwide, hands-on, K-12 school-based science education program.
