If you have ever had to adjust to a new time zone, you have noticed that it takes a while before you start to feel normal again. By shifting your sleep and activity schedule, you have altered the pattern of your body's circadian rhythms....

The article explains temperature. Specifically, you will learn about the temperature scale, temperature scale conversions, and the types of instruments used to measure temperature. Included are solved examples and interactive problems...

The Center for Mathematics and Science Education at the University of North Carolina at Chapel Hill provides an interesting and easy-to-use dictionary of the history and meaning of many measurement terms. Metric, International, and...

Based on experimental observations, students describe, on the molecular level, why the liquid in a thermometer goes up when it is heated and down when it is cooled.

If you're lucky enough to live in a place that gets snow in winter, you know that the feel of the snow can vary a lot. Sometimes it can be light and fluffy, and other times heavy and wet. This project shows you how to use data from daily...

Students practice the engineering design process as they explore devices used to measure changes in temperature. They work in teams to design, build, test, and evaluate their own temperature gauge made from everyday materials.

In this science fair project, use an infrared thermometer to measure the temperature of differently colored paper exposed to sunlight, and calculate energy emission using the Stefan-Boltzmann equation. Find discussion questions, a list...

Learn that temperature measures average kinetic energy, and heat is the transfer of energy from hot systems to cold systems. Consider what makes a good conductor. (Requires Java)

This site from the U.S. Geological Survey provides great definitions of seven measurements that can be taken on water. Includes pH, dissolved oxygen, and turbidity. Click Home to access the site in Spanish.

See how thermometers measure temperature by the molecular movement of the liquid inside.

For this activity, students will be given a set of materials: cardboard, a set of insulating materials (i.e. foam, newspaper, etc.), aluminum foil, and Plexiglas. Students will then become engineers in building a solar oven from the...

Harmful algal blooms occur when algae, which form the base of the ocean food web, grow in massive numbers and produce toxic or harmful effects on people, fish, shellfish, marine mammals, and birds. In this project you will learn how to...

This resource explains the structure of the metric system of measurement; the basic units of measurement for length, volume, and mass; and provides charts for each type of measurement. A chart of customary US units is also given.

Want to learn more about climate change, global warming, and greenhouse gases? This web page contains links to websites around the world concerned with providing information about these. Topics include climate shift, greenhouse effect,...

Lesson plan that allows students to investigate the effect of water temperature on fish behavior. Students measure, collect data, and interpret the results.

This lesson plan familiarizes young scholars in grades 4-6 with using the metric system and performing conversions.

Instructions for how to make an electrical thermometer. The electrical thermometer works like this - the design consists of four resistors each made from about 40 meters of very thin copper wire. The electrical resistance of wire changes...

This activity introduces students to the complex chemistry of estuarine water. Students investigate how chemical and physical water quality factors-pH, temperature, dissolved oxygen, and salinity-change and interact over varying time...

Learners are introduced to the basics of the Earth's weather. Concepts include fundamental causes of common weather phenomena such as temperature changes, wind, clouds, rain and snow. The different factors that affect the weather and the...
