Students learn about the basic properties of light and how light interacts with objects. They are introduced to the additive and subtractive color systems, and the phenomena of refraction. Students further explore the differences between...

Projections and coordinates are key advancements in the geographic sciences that allow us to better understand the nature of the Earth and how to describe location. These innovations in describing the Earth are the basis for everything...

Students complete a self-guided exercise in worksheet format combined with Google Earth that helps them explore practical and observable differences between different projection and coordinate systems. The activity improves their skills...

Cryptids, creatures of questionable existence, are used as a source of data to guide students into the creation of their own GIS data layer in Google Earth. The activity serves the purpose of a tutorial to teach students how to make data...

Students learn how viruses invade host cells and hijack the hosts' cell-reproduction mechanisms in order to make new viruses, which can in turn attack additional host cells. Students also learn how the immune system responds to a viral...

In this unit, students learn the very basics of navigation, including the different kinds of navigation and their purpose. The concepts of relative and absolute location, latitude, longitude and cardinal directions are discussed, as well...

Students use a watt meter to measure energy input into a hot plate or hot pot used to heat water. The theoretical amount of energy required to raise the water by the measure temperature change is calculated and compared to the electrical...

Several activities are included to teach and research the differences between renewable and non-renewable resources and various energy resources. Students work with a quantitative, but simple model of energy resources to show how rapidly...

Students will learn about bone structure, bone development and growth, and bone functions. Later, students will apply this understanding to answer the Challenge Question presented in the "Fix the Hip" lesson and use the acquired learning...

In this activity students will learn the basic concept of Global Positioning Systems (GPS) using triangulation and measurement on a small scale in the classroom. Students discover how GPS and navigation integrate mathematic and...

This lesson describes the major components and functions of the immune system and the role of engineers in keeping the body healthy (e.g., vaccinations and antibiotics, among other things). This lesson also discusses how an astronaut's...

Students are introduced to air masses, with an emphasis on the differences between and characteristics of high - versus low-pressure air systems. Students also hear about weather forecasting instrumentation and how engineers work to...

This lesson plan helps students explore the functions of the kidney and its place in the urinary system. Students learn how engineers design instruments to help people when kidneys are not functioning properly or when environmental...

For thousands of years, navigators have looked to the sky for direction. Today, celestial navigation has simply switched from using natural objects to human-created satellites. A constellation of satellites, called the Global Positioning...

This activity explains what a fever is and how the immune system uses it to try and protect the body against germs. The students then explore temperature further by creating a model of a thermometer and completing a temperature...

What do you know about the respiratory system? This site gives a detailed description of this integral human body system. Don't miss out.

[Free Registration/Login Required] Using video content and assessment integration students will learn about the human muscular system.

A comprehensive tutorial that depicts the parts of a subsystem within a system. This tutorial dissects a rocket and explains how each part is integral to its actual functioning. Excellent links to otherresources dealing with aerodynamics.

[Free Registration/Login may be required to access all resource tools.] Students explore the scientific implications of measurement, and learn about system international metrics, dimensional analysis, scientific notation, and more.

[Free Registration/Login may be required to access all resource tools.] Students investigate how all types of energy, including work, relate to each other and are conserved in a closed system.

In this activity students will work with municipal data and computer mapping to determine the priorities of emergency response to flooding in a local town. This can be used as a lab activity or as a group or individual project, and can...
