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...

Young scholars 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.

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.

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,...

Read about the use of data loggers in one high school class. The data loggers were the key to quantifying the relationship between temperature, light, and biodiversity. Although this is relevant to high school science links are provided...

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

This micro-field guide was created by 5th and 6th graders in Marlboro, Vermont. Groups of 3 or 4 students worked together to investigate their own 3 by 3 foot research plot, over multiple visits, and then created a field guide to their...

Look to this site for many important numbers and conversion factors used between the metric system and the customary system, such as speed of light, body temperature, distance from sun to earth, plus more.

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...

Scientists have warned that as CO2 levels in the atmosphere rise an increase in Earth's temperature by even two degrees could lead to catastrophic effects across the world. But how can such a tiny, measurable change in one factor lead to...

Students 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...
