This website provides explanations of mass, weight, and density with directions for building simple scales and balances. Provided as encouragement to teach these concepts to young children, it offers a good review for older students.

Resource contains and example problem and solution of how to compute percent compound within a mixture when given the mixture's mass and element percents.

Students conduct a hands-on investigation to determine how matter, changing state, effects the property of weight. Students will collect data and graph their results. Resources include step by step instructions, a data worksheet, videos...

Use this interactive body mass index calculator to determine if your weight is under, over or normal for your size and read about things you can do to maintain a healthy weight.

This site gives an explanation that distinguishes mass from weight. It distinguishes between the two types of mass (inertial and gravitational), and gives the equations for computing both.

Students learn the difference between weight and mass. Practice problems are included to check for comprehension of the concept.

This lesson explains many basic concepts of atomic structure. It starts with atomic mass and number and then works up to more sophisticated information on electron configuration and how each element fits into the Periodic Table.

The purpose of this lesson is to help students understand the relationship between the mass and the weight of an object. Students will study the properties of common materials and why airplanes use specific materials.

Lars in Antarctica needs help. Can you help him with all the months of the year and with mass?

In this lesson, students will investigate why the Cartesian diver dives and rises in a 2 liter bottle. They will also, through their own discovery, come up with a question and then change one variable and record their results. Students...

On this interactive site students learn to use various units of mass to solve problems and put objects in order by their mass.

In this activity, students use a Dual Range Force Sensor to measure the weight of pennies. They understand the difference between mass and weight. Students also determine the difference in weight of an object on the moon, Mars, Saturn,...

Students explore the meaning of density and use their math skills to graph mass/volume data, write an equation for a line, and interpret the slope of the line. Students also find the density of two unknown mineral samples and use those...

This article on weight will help you prepare for the AP Physics test. Included are example problems to help you practice.

[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...

Peruse this resource to learn about gravity, its importance, the Universal Law of Gravitation, the difference between mass and weight, and more fun facts.

Could the location of the Olympic host city have an effect on weightlifting events? This activity provides an interesting context in which to engage with weight, mass and gravitation, and is aimed at A-level students (grades 10, 11, and...

Third graders will understand weight, mass, and gravity.

Hang various mass weights on spring scales while you adjust the spring stiffness and damping in this online activity. Slow down the action, take it to another planet, or watch the amount of potential, thermal, and kinetic energy.

Students learn about the concept of pushing, as well as the relationship between force and mass. Students practice measurement skills using pan scales and rulers to make predictions about mass and distance. A LEGO MINDSTORMS NXT robot is...

Learn about body mass index and how this number affects your overall health. Then plug in your own data to find your BMI.

The learning activity explores weight. Students weight different items and compare their mass from smallest to largest.

[Free Registration/Login Required] An informational text debating whether or not schools should send reports home about students' body mass index (BMI). A question sheet is available to help students build skills in reading comprehension.

Students learn about standard units of mass. Topics include ounce, pound, and ton. Practice problems are included to check for comprehension of the concept.
