Simply hold a rod between your thumb and forefinger at one of the three marked nodes. Place a little of the included special rosin on your other hand. Then rub that hand along the rod from middle to end. As you stroke, friction creates a standing wave pattern which emits a tone that grows louder with each stroke. The resulting high-pitched ringing is sure to wake up everyone in class! The rod is marked at the quarter and halfway points. Holding it at the halfway point makes that spot a nodal point and creates the first harmonic. Moving your hand to a quarter point forces the second harmonic — and a higher pitch! (These and other experiments are discussed in the included explanation/activity sheet.) Dramatically demonstrates nodes, anti-nodes and standing waves A must for explorations of sound and waves, these rods are an easy way to demonstrate longitudinal waves as opposed to transverse waves. They’re ideal for teaching about nodes and anti-nodes in standing waves. And they’re a great follow-up activity to see if students really understand sound and waves. You get two rods (75 cm and 50 cm), so you can demonstrate the relationship of pitch to length.

The Plasma Mug makes a great gift idea for science enthusiasts! Plasma Globe Plasma Generators — Great Balls of Fire! Safely create and explore lightning, right in your classroom These popular Plasma items give you a safe, fascinating way to demonstrate how lightning works as well as an explanation of the concepts of potential differences and electron orbital jumping. A small Tesla coil produces a large potential difference between it and the surrounding glass, similar to a cloud and its potential difference with the ground. A small Tesla coil generates a large potential difference to simulate lightning. Students see how light is produced from charged gases. Plasma Mug This potential difference uses inert gases inside the globe to complete a circuit and release its potential to the outer glass, just as a cloud releases its potential to the ground. The result? Bright, harmless, violet “lightning bolts” that respond to touch and sound. For more information and power requirements for each item, visit www.arborsci.com.

Boyle’s Law: P1 V1 P2 V2 SUBSCRIBE TO How many breaths would it take to inflate an 8-foot long bag?… and why would you care? The long plastic bag nicely incorporates Bernoulli’s principle. If you were to blow it up by placing it firmly to your mouth, many lung-fulls of air would be needed. But when you hold it in front of your mouth and blow, air pressure in the stream you produce is reduced, entrapping surrounding air to join in filling up the bag. So you can blow it up with a single breath! This is especially effective after your students have counted many of their own breaths in attempting to fill up the bag! Paul G.

Captivating Energy Demonstration If you’ve ever watched a coin spinning on a tabletop, then you’ve got to see Euler’s Disk. Constructed of heavy metal and a smooth concave surface, this device elegantly demonstrates conservation of energy and angular momentum. Just give the disk a twist and watch it spin and roll for an amazingly long time! Can your students explain why the disk rotates for so long, or why it rotates faster as it gets closer to the surface? Explanations can range from simple statements of energy conservation to complex physics equations such as the work of Leonard Euler (“Oiler”), for whom the disk is named. Mirror is 9" in diameter!

Turn ordinary water into a white fluffy substance that looks like real snow. Kit contains one 40 g. bag of Insta-Snow as well as 24, 7g tubes for students. Non-hazardous and environmentally safe. Air Cannon Remember the trash can vortex launcher? This new Air Cannon sends a strong blast of air all the way across the room! Use the crosshairs to aim, pull back on the handle, and let go. The elastic forces air out the hole, forming a vortex, which travels up to 30 feet! Use dry ice to create fog and launch 6-inch smoke rings! Explanation included.

Drinking Bird Almost everyone remembers this hard-to-find toy with at least a twinge of nostalgia — now he’s back, disguised as a great physics demonstration of heat and thermodynamics. This lugubrious little lorikeet dips his beak into a glass of water as evaporative cooling induces the rise of a volatile liquid from his tail towards his head. As he dunks, the liquid returns to his tail, the bird rises, and the process begins again. Not recommended for instructors under four years of age. P3-5001 Drinking Bird $5.75 NEW! Rocket Car Experiment Kit Fuel the Rocket Car with baking soda and vinegar, insert the fueling module, and your land speed challenger will be ready to roar off. You’ll see chemistry and physics in a new light after a day racing the Rocket Car. Our baking soda and vinegar formula starts a powerful chemical reaction that will propel the Rocket Car over 200 feet. You can experiment with the proportions to create your own secret rocket fuel mixture.

Award-winning physics teacher Buzz Putnam shares his secrets to grabbing students’ attention and making them think! Discrepant events are really just magic tricks for science class, and we’ve collected a dozen favorites. This kit includes 6 ready-made demos and instructions to make 6 more from common items. We’ve even included a Teacher’s Guide and a video of Buzz himself, so you can perfect your own style and timing. Demo example: The Balloon Challenge shown above presents students with a question; If the air valve is opened between the larger and smaller balloons what will happen? Intuition says the larger balloon would continue to inflate the smaller balloon until equilibrium is achieved. But a discrepant event is one where the outcome is not what you expect! Get more details on this and the 11 other great demos included in this kit along with a sample video clip at www.arborsci.com. P6-6025 Discrepant Events Kit $99 ▲ Balloon Duel Challenge: When the valves are opened, what will happen? Maybe not what you think! Kit includes video of each demo. Watch, laugh, learn from the master, and amaze your students with science magic.

P8-0620 $38.50 Balancing Bird Kids are always amazed when they see this bird balance on anything — its stand, a finger, even a nose! But it doesn’t defy gravity — it takes advantage of it. Thanks to two well-placed weights at the end of its wings, its center of mass is located below the tip of its beak, creating a stable equilibrium. Show students how deceiving an object’s center of mass can be, spin it on its stand to demonstrate rotational motion, or discuss movement in two systems by moving the stand through the air to add translational motion.

Celt — Puzzling! A deceptively simplelooking piece of molded acrylic polystyrene provides a fascinating demonstration of center of gravity and physics. Tap one end, and the Celt will mysteriously begin to spin. Spin the Celt clockwise, and it will reverse direction.

So explore projectile motion with this 100% safe, chemical-free air-powered projectile. Accurate and repeatable to an amazing degree Projectile Launch Pad Seller! BEST Thanks to the hard-plastic chassis, this missile flies straight and true with minimal wind effect. Since it takes off at the same velocity every time, your outcome is always precise and consistent — important for students testing predictions, who’ll reap rewarding results. And it’s a breeze to use. All you do is pressurize the launch chamber with an ordinary bicycle pump. When the pressure is high enough to pop off the thrust washer, the projectile blasts into the sky. Each projectile comes with four different thrust washers — Low, Medium, High, Super — so you can vary launch speed for different experiments. You can even build a launch pad (or use the one to the right) to vary launch angles. Then your students can use Newton’s Laws to predict where the projectile will land! For Air Powered Projectile Lab Software, see Interactive Physics on page 31 This easy-to-use launch pad utilizes six wedges (sold separately) that let you vary the launch angle from 30˚ to 55˚ (in increments of 5˚) so you can explore different aspects of projectile motion and Newton’s Laws. Comes unassembled. Achieve repeatable and predictable results! Heavy-duty Air Pump! NEW & Improved Design! Set of 6 wedges to vary launch angles and set of 4 washers to vary launch speed.
