Matter: Mass and Weight
What is the difference between mass and weight? Find out by using these sites. Includes lesson plans, classroom activities, and animation. There are eThemes resources on metric measurement, gravity, properties of matter, and phases of matter (gas, liquid, and solid).
BrainPOP: Mass, Volume, and Density
Watch Tim and Moby explain about mass and weight. NOTE: Site available by subscription only.
Your Weight on Other Worlds
Students can find out what they would weigh on another planet. Students should only put a number in the "Enter your Weight Here." This text may be too advanced for younger students, but there is good background information for teachers.
Ask Dr. Math: Mass versus Weight
Teachers can learn about the difference between mass and weight. Note: This site includes ad.
Mass, Weight, and Density
Teachers can learn the difference between mass, weight, and density. Included are instructions to construct a simple mass balance and a weight scale. Note: This site is appropriate for older students.
This lesson plan for fourth graders has them using a balance.

Gravity and Weight on Other Planets
In this lesson plan, students will learn about mass, weight, and gravity. Note: This site includes ads.
eThemes Resource: Math: Metric Measurement
These sites are about length, volume, mass, and temperature and the metric system. Learn the history of the system and what the prefixes mean. Includes several sites that do online conversions, games, and in class activities.
eThemes Resource: Physics: Gravity
These sites explain how the earth's gravity works. Includes photos, simulations, videos, hands-on activities, and online quizzes.
eThemes Resource: Matter: Properties
Find out how properties of matter describe its various states. Discover the states of matter that exist on our planet and in the universe. Includes experiments with different states of matter and observing the changes as well as animated movies, lesson plans, worksheets, and online quizzes. Several sites have lesson plans for teachers.
eThemes Resource: Matter: Gases, Liquids, and Solids
These sites explain and define the three stages (or phases) of matter: gas, liquid, and solid. There is also information about a fourth phase called plasmas. Includes animations of particles, videos, illustrations, and activity ideas. There are link to eThemes resources on the properties of matter and mass and weight.
