Students explore the concepts of center of mass and static equilibrium by seeing how non-symmetrical objects balance. Using a paper cut-out shape of a parrot sitting on a wire coat hanger, they learn that their parrot exists in stable...

In this activity, students will learn about Newton's 2nd Law of Motion. They will learn that the force required to move a book is proportional to the weight of the book. Engineers use this relationship to determine how much force they...

On this site, find a variety of materials to help students understand the conservation of matter. Create lessons that allow students to measure and graph quantities that could show even if matter is heated, cooled or combined with other...

Manipulate the mass of a weight and the length of string in this interactive pendulum simulation. Change the speed, friction, and gravity to make the pendulum swing change as measurements are displayed on the screen. Younger students can...

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.

Students work as physicists to understand centripetal acceleration concepts. They also learn about a good robot design and the accelerometer sensor. They also learn about the relationship between centripetal acceleration and centripetal...

Participate in the investigation of a virtual crime scene using chemistry concepts to solve a mysterious death. The 40-50 minute activity can be used as a classroom lab or as a homework assignment. Additionally, teachers may request a...

Discover the many disorders associated with obesity, and learn how this epidemic affects us in today's society.

Students explore Hooke's law while working in small groups at their lab benches. They collect displacement data for springs with unknown spring constants, k, by adding various masses of known weight. After exploring Hooke's law and...

By the end of this section, you will be able to define net force, external force, and system; understand Newton's second law of motion; and apply Newton's second law to determine the weight of an object.

[Free Registration/Login may be required to access all resource tools.] For this learning module, students must subtract mixed metric units of weight. Includes video demonstrating a sample problem [0:53] and a set of practice questions.

[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...

Newton's three laws are deceptively simple, but they are the underpinning of all of physics and govern the mechanics all of your actions in everyday life. Take an in-depth look at these laws in this learning module.

The Center for Mathematics and Science Education at the University of North Carolina at Chapel Hill provides an interesting and easy-to-use dictionary of the history and meaning of many measurement terms. Metric, International, and...

Review the key concepts, equations, and skills for Newton's first law of motion, including the difference between mass and weight.

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,...

Conversion calculators galore! Convert just about anything from one measureable unit into another measureable unit here with over two dozen calculators. Each of the links is specific to a measureable quantity. Some examples include...

Weigh five little creatures on a metric scale, and subtract to find the mass to the hundredths place for each. A timer calculates your speed of computation.

Use this converter to find equivalent units for a measure. You can convert measures for area, length, weight, temperature, and volume.
