AP9301 - $5.50
How does this bird defy the laws of gravity? Because of two well-placed weights at the end of its colorful wings, its center of gravity is located at the very tip of its beak. Spin it on its stand or balance it on a finger. Wingspan of 6 1/2"....
AP6376 - $13.55
This balancing act will be a real attention getter! Students will remember the concept of the center of gravity involved in this demonstration. A large water-filled bottle and a wooden board seem to defy gravity as together they balance on the board's...
AP7065 - $14.70
Easily show your students how to locate the center of gravity of an irregularly shaped object. Once the center of gravity is determined, insert a pencil inot the proper "center of gravity" hole and spin the object—it will rotate smoothly....
AP7066 - $16.25
Effectively show that the path of an irregularly shaped object, when thrown in the air, is a parabola—just as Newton predicted! Locate the center of mass of the “irregular” foam object by hanging a small weight from three corners of the object. Mark...
AP7068 - $49.70
Balance your physical science curriculum with our most popular center of gravity demonstrations-all available in one complete set! Quickly show your students how to locate the center of gravity of an object using a hanging plumb line. Watch the object...
AP4671 - $25.70
Discrepant events are powerful teaching opportunities. And the Center of Gravity Paradox is a “dandy.” Everyone knows that a low center of gravity is more stable than a high center of gravity. Your students' thinking caps will have to go on in order...
AP6836 - $5.10
Introduce the concept of center of mass with this inquiry based lesson. First, lay the center of mass bottle on its side. Your students will think this is simple enough. Then, pick up the bottle and secretly allow the counterweight inside the bottle...
AP7067 - $60.65
Challenge students to locate the center of gravity for objects of various shapes. Students place the corner of one polygon on a hook so that the object hangs freely. Then, they hang a weight tied to string from the same corner. Using a dry-erase marker,...
AP4712 - $38.05
Can something roll uphill? Students will be amazed as the cone in this demonstration appears to magically roll uphill. Careful inspection will reveal that the apparent gravity-defying paradox is really not what it appears to be. The center of gravity...
AP6486 - $19.60
Show the connection between center of gravity and stability. With this quick and effective hands-on experiment, students explore center of gravity principles, and learn why a tower with a low center of gravity can be tilted farther than one with a...
AP6640 - $14.15
Here's a paradox-a device that remains balanced when a heavy plastic tube dangles from one end while being supported at the opposite end by a single fingertip. Remove the tube and the device falls. How can this be? It's center of gravity! This simple...
AP6689 - $27.60
What principles must engineers follow to build safe structures such as bridges, buildings, or even a simple hanging sign? In this hands-on lab, students become structural engineers as they experiment with a simple form truss to determine the most structurally...
AP6762 - $111.60
What principles must engineers follow to build safe structures such as bridges, buildings, or even a simple hanging sign? In this hands-on lab, students become structural engineers as they experiment with a simple form truss to determine the most structurally...
AP4603 - $102.95
Students discover firsthand how the balance point of a system is affected by mass distribution. First, they measure the mass of randomly selected plastic tubing, steel rod and wood dowel. Next, they combine the pieces in a specific configuration and...
