Ninth graders explore the concepts of motion, velocity and acceleration through graphing their own movement using LoggerPro. They become more familiar with the computer technology. Students explore graphing in real time and graph on...

What is a chemist's favorite plant? Stoichiome Tree! Scholars produce hydrogen gas by reacting magnesium with hydrochloric acid. Then they calculate the molar volume of the gas produced before answering assessment questions. 

Learners discuss the importance of water in our daily lives. For this physics lesson, students calculate the pressure of water tower systems. They investigate the effect of certain variables using a computer simulation.

For this mass worksheet, students fill out a two column notes sheet about mass. Students fill in short answers for 17 places in the notes sheet.

By the end of this section, you will be able to do the following: Perform unit conversions in both SI and English units, Explain the most common prefixes of SI units, and be able to write them in scientific notation.

[Free Registration/Login may be required to access all resource tools.] In this lesson, students will describe the International System of Units (SI) and be able to convert units between International and English systems.

[Free Registration/Login may be required to access all resource tools.] In this online tutorial students will begin to identify the seven base units of the International System of Units. They will understand the commonly used metric...

Students use three tracks marked on the floor, one in yards, one in feet and one in inches. As they start and stop a robot specific distances on a "runway," they can easily determine the equivalent measurements in other units by looking...

The learning resource discusses units, dimensions, and measures used in Chemistry. Some topics explored are dimension, symbols in metric units and symbols in English units. The activity consists of definitions and explanations.

As part of a larger site called "Getting started in Chemistry," this site examines the units of scientific measurement with specific attention given to SI base units, SI decimal prefixes, units outside SI, and more.

Here's where to obtain your official brochure on SI, from the people who derived it. Little info at this site, except how to order an official brochure (and its cost). Or you can download a copy free.

By the end of this section, you will be able to associate physical quantities with their International System of Units (SI) and perform conversions among SI units using scientific notation; relate measurement uncertainty to significant...

The innovative resource introduces learners to setting a scale when making measurements, units of measurement, and entomology. The activity has an interactive online version and a printable data sheet.

[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.

An interactive tutorial teaching the basics of measurements and units. Anyone can learn the SI units of measurement with this easy-to-understand slideshow.

Learn about physical quantities, SI units, and derived units in this chapter of a physics of textbook.

BIPM (Bureau International des Poids et Mesures) is an international organization, located in France, an equivalent of our National Institute of Standards and Technology (NIST). This site is the BIPM intro page to their official...

This is the definitive source for information on SI base units, derived units, squares, cubes, luminosity, field strength and flux density.

A tutorial which introduces the International System of Units, and its use in making measurements during scientific investigation.

Very complete chart of conversion factors for English to SI (metric) unit measurements and SI (metric) to English unit measurements. Includes length, area, volume, mass, temperature, illumination, and force & mass (stress).

This site examines the specific difference between mass and weight in addition to length, temperature, and time.

The world's roundest object helps solve the longest running problem in measurement- how to define the kilogram. A kilogram isn't what it used to be. Literally. The name, weight, and definition of a kilogram has been changing constantly...

As part of a larger site called "Getting started in Chemistry," this site examines various topics related to measurements and the error and uncertainty that accompanies the methods of measurements.

This activity assesses students' knowledge and understanding of measurement and science.
