Energy is often defined as "the ability to do work." In this module we will see how energy flows through different states as it affects our world. You can also work on an experiment to see how much energy it takes to boil water! We will get a feeling for the vast scale of energy; from heating a single atom to the energy in our galaxy.
A Walk Through Time
This sit elooks at the evolution of time keeping, how humans have measured the passage of time throughout history. The site describes and shows depictions of ancient calendars, sun and water clocks, mechanical and quartz clocks, and world time scales and time zones.
Biology of Water and Health
This course encourages and trains students to think outside the box when addressing water-related problems. Our interdisciplinary approach is designed, for example,to give the health professional an introduction to the engineering components involved in the provision of safe water and sanitation. While at the same time providing the engineer an ecological framework for understanding the place of water in health, it also gives a voice to the ways in which water is involved in social interactions,
Despite gobs of data, it is still difficult to accurately predict the path and intensity of a hurricane. How are these predictions made? Are they getting more reliable? Will hurricanes be affected by global warming? And, while we're at it, what gets a hurricane turning in the first place?
Acids and Bases
You can access the problems below via the Load Homework dialogue in the File menu of the Virtual Lab. They have been organized by concept and ranked by difficulty (A ranking of 1 denotes an easier problem; 5 is more challenging). Word files for these problems are provided so that you may edit and distribute the assignments in your classroom. The following types of problems can be found:Strong and Weak Acid and Base Problems, Determination of the pH Scale by the Method of Successive Dilutions, St
When you work in a laboratory, chances are you are starting off with a concentrated stock solution. Being able to create solutions of varying concentration from this is a useful skill. Solutions with known concentrations are often called "standard solutions." You can learn about the concept of dilution and how to use dilution to make a standard solution from a stockroom solution in the following video.
You and a friend are hiking the Appalachian Trail when a storm comes through. You stop to eat, but find that all available firewood is too wet to start a fire. From your Chem 106 class, you remember that heat is given off by some chemical reactions; if you could mix two solutions together to produce an exothermic reaction, you might be able to cook the food you brought along for the hike. Luckily, being the dedicated chemist that you are, you never go anywhere without taking along a couple chemi

Study of Place: Antarctic Exploration
Each two-week module in the Study of Place curriculum is framed by an historical event that makes a connection between the physical environment and human activity. The activities focus primarily on physical and earth science content, geography, and inquiry skills. Assessments and scoring rubrics, including a pre-assessment that can be used for both modules, are embedded in each module, providing opportunities for tracking student learning. The Antarctic Exploration module is framed by Sir Ernest

Exploring Earth: Visualizations
This site features over 100 animations and images that illuminate key concepts in earth science. Examples are: coal formation, nuclear fission, growth of a continent, tectonic plate movement, volcanoes and earthquakes, fault motion, geyser eruption, wave motion, tornadoes, hurricanes, and more. Students can observe a single place on earth from multiple views, 3-D models of water and common molecules, different climate zones, and seasonal changes in the amount of sunlight reaching locations on ea
Exploring Earth: Investigations
This site provides more than 75 earth science investigations. Each presents photos and text (and sometimes video) that help students understand key earth science concepts. Among the topics: earth's layers, rocks, volcanoes and plate tectonics, earthquakes and mountains, surface and ground water, wind and currents, atmosphere and weather, climate change, oceans, our moon and solar system, and earth's history.
Take a Technology Inventory
This activity prepares students to watch the film, "Local Voices, Global Visions," by having them examine the presence of technology in their own lives. Students should be familiar with the use of spreadsheets and have a basic working definition of information and communication technology (ICT), using the Understanding page or from their own initial research on the subject. This activity is part of a series of lessons surrounding the film, "Local Voices, Global Visions."
Slave Narratives: A Genre Study
In this lesson, students will read selected excerpts from slave narratives, determining common characteristics of the genre. Students will then write their own slave narratives as a slave from their region of North Carolina, researching for historical accuracy and incorporating elements of the slave narrative genre to demonstrate understanding.
Development and Flooding: Is There a Connection?
In this lesson, students will take their knowledge about the hydrosphere and apply it to the issue of population growth and development. In particular, students will learn how increasing development in eastern North Carolina may have worsened the effects of flooding from Hurricane Floyd, due to lack of soil and tree absorption of run-off. Students will create their own development plans for North Carolina in small groups, explaining how their plan will benefit North Carolina’s water resources
De Facto vs. De Jure Segregation
In this lesson, students will contrast and compare de facto and de jure segregation, listening to oral history examples of each from residents of Charlotte, North Carolina. Students will then brainstorm solutions to each type of segregation, and will discuss why de facto segregation can persist even after de jure segregation is eliminated.
The Snowball Earth
This website contains an informational paper by Paul Hoffman and Daniel Schragg at Harvard University. The paper describes many lines of evidence supporting a theory that the entire Earth was ice-covered 600-700 million years ago. Each glacial period lasted for millions of years and ended violently under extreme greenhouse conditions. These climate shocks triggered the evolution of multicellular animal life, and challenge long-held assumptions regarding the limits of global change. Users can rea
Physical geography is the study of the earth's dynamic systems -- its air, water, weather climate, landforms, rocks, soils, plants, ecosystems and biomes -- and how humans interact with the earth's systems. Physical geography is the study of the world around you. Everyone, every day, interacts with the earth's dynamic systems. I challenge you to join me on an exploration of the complex, and exciting world in which you live! This is a freshman level college course in physical geography. It requir
Water and human health
Water is a natural resource that is vital for human survival and health, although only a tiny fraction of the Earth's supply is available to humans and terrestrial animals. In this unit we look at threats, such as pollution, to water's capacity to support life around the world.
Water for life
Atoms, elements and molecules are the building blocks of everything that makes up our world, including ourselves. In this unit you will learn the basic chemistry of how these components work together, starting with a chemical compound we are all very familiar with – water.
