Explore the concept of the calorie. Determine the calories/gram of the burned food by measuring its mass, and make conclusions about the experimental design.

This lab is designed to have students learn how to use a meter stick to create and calibrate a scale. This lab can be used as a stand alone lab or as a companion to a live lab using the same equipment. This lab is intended to be done...

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 provides a great overview of stoichiometry, the part of chemistry that studies amounts of substances that are involved in reactions. Content focuses on what you measure, and includes two examples.

Vasarosnamenyi Baro Eotvos Lorand, better known as Roland Eotvos or Lorand Eotvos throughout much of the world, was a Hungarian physicist who is most recognized for his extensive experimental work involving gravity, but who also made...

This page provides eight tables of useful information such as Important Constants, Submicroscopic Masses, Solar System Data, Metric Prefixes for Powers of Ten and Their Symbols, The Greek Alphabet, SI units, Useful Formulae, and other...

Discover atoms and molecules which make up matter, motion of atoms and how to measure the mass, volume and density of matter.

Students will use two different methods to determine the densities of a variety of materials and objects. The first method involves direct measurement of the volumes of objects that have simple geometric shapes, while the second uses the...

Adjust mountain snowfall and temperature to see the glacier grow and shrink. Use scientific tools to measure thickness, velocity and glacial budget.

Students explore the use of several biomedical engineering sensor devices, and then use the collected data to create and analyze scatterplots of the different variables to determine if any relationships exist between the measured...

[Free Registration/Login may be required to access all resource tools.] Convert among metric units of measure using powers of 10.

Convert between US customary measures of distance, volume, and mass. Students receive immediate feedback and have the opportunity to try questions repeatedly, watch a video or receive hints.

A lesson where students collect trash, sort, and record the mass in grams. They will use their knowledge of numbers to figure out what category of trash had the most. The biggest idea of the lesson is that students will be more likely to...

Students learn how to measure things using US Standard Units. Liquids, mass, length, and temperature are explored. Practice problems are included.

[Free Registration/Login may be required to access all resource tools.] In the following online tutorial students will identify three methods for measuring the amount of matter in a sample. They will define the mole and its relationship...

Students do work by lifting a known mass over a period of time. The mass and measured distance and time is used to calculate force, work, energy and power in metric units. The students' power is then compared to horse power and the power...

Activity helps students understand force, mass, and measurement.

In this first part of a two-part lab activity, students use triple balance beams and graduated cylinders to take measurements and calculate the densities of several common, irregularly shaped objects with the purpose to resolve confusion...

Students discover the concept that density is a characteristic property of water by measuring the volume and mass of water and calculating its density.

In this interactive lesson, learn what the "physical properties" of matter are and how can they be measured and observed.

The concern over obesity in children in the United States is staggering. This site provides research and statistics along with suggesting ways to change the epidemic. Includes video.

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

Need a unit converter? Links to the most common converters provide access to the answers you need quickly.

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.
