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.

This interactive game has students apply skills in estimation, measurement, and basic addition using pearls. Students are asked to estimate the number of pearls in a treasure chest by making predictions and using number sense. The skills...

Several learning modules that explain the difference between mass and weight. Each module includes a video introduction and detailed lesson plan.

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.

[Free Registration/Login may be required to access all resource tools.] Definition of weight and how to calculate the weight of an object.

This lesson focuses on gravitational fields and includes what one is, the formula for gravity force, defining weight, formula for mass, an example of how to calculate gravity force, a practice question, and a link to a test.

Using a Periodic table with a list of atomic weights for reference, practice figuring moles of 103 elements.

Covers the meanings of force, friction, and gravity, and the differences between magnetic and elastic spring force, and between weight and mass. The effect of air resistance on an object's motion is also touched upon.

A comprehensive guide for learning all about mass with definitions, how to calculate mass, the difference between mass and weight, solved examples, and practice questions.

Learners 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...

A tutorial exploring the relationship between mass and weight. The tutorial also explains the difference between the concepts through pictures and examples.

Join Maria and Boris the Astronaut in their journey. Learn about mass, weight, and gravity in space.

This task challenges a student to use understanding of measurement to convert accurately between units of weight.

In this student-paced module, students apply Newton's Laws of Motion to everyday life, calculate mathematical relationships involving force and motion using algebraic formulas, and understand the difference between mass and weight.

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...

Through ten lessons and numerous activities, students explore the natural universal rules engineers and physicists use to understand how things move and stay still. Together, these rules are called "mechanics." The study of mechanics is...

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

Think about the relationships between weight and size of similar objects. This interactive exercise focuses on using critical thinking skills and estimation skills to predict how many mini and regular gummy bears it takes to have the...

Take a quick trip to the other planets, and hop on the scale to find out how weight there compares to weight on Earth.

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...

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

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.

[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.
