Bowling Ball Pendulum

AP6839

Demonstrate the conservation of energy with a real classic! Hold a heavy bowling ball pendulum against the tip of your nose. Release the bowling ball without moving your head and allow it to swing through its pendulum arc. The students' shock and fea...

Wrecking Ball

AP7799

Smash through barriers in student understanding of energy and motion! Build a structure using the included wooden planks, turn the crank to wind the hoist rope and then watch the destruction. A great lesson on pendulums, collisions, and how energy is...

Balancing Bird

AP9301

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". C...

Center of Gravity Demostration Set

AP7068

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 objec...

Center of Gravity Toss - Demonstration Kit

AP7066

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 ...

Center of Mass Bottles

AP6836

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 ...

Diving Eggs Inertia Challenge - Newton's First Law Demonstration

AP7419

Students experience the effects of inertia every day—riding in a car, playing sports, even picking up their backpacks. Present a more dramatic demonstration of Newton’s law of inertia by safely and simultaneously dropping three eggs into beakers of w...

Double Cone and Ramp

AP4712

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...

Fascinating Finger Balance Demonstrator

AP6640

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...

Center of Gravity Paradox

AP4671

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 ...

Guinea and Feather Tube

AP4670

Objects fall with the same acceleration-don't they? Watch and compare the falling acceleration rate of a feather and a guinea (coin) with air resistance and in a vacuum using this clear acrylic demonstration tube. The results are unforgettable! The s...

Galileo's Paradox - Hinged Stick vs. Falling Ball Demonstration Kit

AP6693

In the blink of an eye, illustrate important concepts such as torque, acceleration and center of mass with this discrepant event demonstration. A stick with a cup near one end and a hinge at the other is propped at an angle with a support rod. A ball...

Personal Hovercraft - Demonstration Kit

AP7516

It’s not a flying car, but it’s the next best thing! Entertain while you educate your students with Flinn’s amazing personal hovercraft. This vehicle is perfect for the study of Newton’s three laws of motion. Apply a one-time force to the hovercraft ...

Inertia Ball/Pendulum Bob

AP6037

Dual-purpose, heavy-duty zinc ball can double as a pendulum bob or as the key element in a dramatic inertia demonstration. Use one of the provided eyelets, attach a string, suspend the bob, and you have a large demonstration pendulum.
Attach anothe...

Inertia Device

AP4538

Demonstrate Newton's First Law of Motion-a body at rest tends to remain at rest. When the metal spring bar is snapped, the cardboard square is shot through the air while the metal ball remains in place on the stand.

Inertial Balance

AP4607

Imagine this theoretical problem-you try to push a block on a horizontal, frictionless surface in a region of space that is free from gravity. It will still require some effort to move the block, i.e., change its motion. It is the mass of the block a...

Kinetic Energy Ball Drop Demonstration

AP7187

Will a ball traveling twice as fast as another ball of the same mass really have four times the kinetic energy? Demonstrate the relationship between speed and kinetic energy by dropping a ball from two different heights onto a bed of soft clay. For t...

Loop-de-Loop Track

AP7109

Effectively demonstrate the conservation of energy as potential energy is converted into kinetic energy. How high must the ball begin on the track in order to make it all the way around the loop? An excellent demonstration to begin a discussion about...

Magnetic Linear Accelerator

AP6838

Amazing! A slow-moving ball bearing collides with a magnet-ball bearing system, knocking away the last ball in the series, obeying the conservation of momentum. One problem-the knocked-away ball appears to shoot at nearly three times the original spe...

Modeling Projectile Motion

AP7039

Visibly demonstrate the parabolic path of a projectile with this simple model. Use the model to illustrate many concepts in dynamics. Small weights hang at different distances below a meter stick to show how the location of an object changes every 0....

Momentum and Collisions Demonstration Kit

AP7399

Which collision imparts more momentum—an object that hits a block of wood and sticks to it, or an object that bounces straight off? The answer will knock over one of the blocks, not to mention your students! This simple but effective demonstration us...

Newtonian Demonstrator

AP6913

This classic demonstrator is perfect for illustrating Newton's laws of motion and the conservation of momentum. The large swinging balls can be manually aligned to produce nearly perfect elastic collisions. High-quality wooden construction will last ...

Newtonian Demonstrator, Economy Choice

AP9211

Demonstrate that for every action there is an equal and opposite reaction. Lift and drop one ball to see one ball pop out from the other side. Lift two balls and two pop out. Leave this popular “toy” on your desk for a school year of enjoyment and le...

Projectile Launcher

AP5696

Easy to set up, repeatable results, unbreakable. These are the qualities you need in an apparatus for your projectile motion experiments. This all-metal launcher can be clamped to any lab table, at any angle from -15º to 90º, in a matter of seconds. ...

PSworks Parabola
