Spirometry Lung Volume Kit 14-piece manual spirometry set used to study the volume of gas in the lungs during the respiratory cycle, an integral part of pulmonary function tests Kit includes 4 mouthpieces, 4 plastic bags calibrated to 6L, and 6 elastic mouthpiece holders Great for…

The Earth/sun system demonstrates the seasons, eclipses, and the phases of the moon. The sun has a LED that sends a spot of light onto the Earth. The sun turns with the handle as the user changes the seasons. The moon revolves around the Earth as the Earth rotates around on its axis. The angle of…

The Loop the Loop Track demonstrates centripetal acceleration and the transformation of potential energy into kinetic energy. Included is a sturdy base with rubber feet, metal ramp with loop, 16mm steel ball and 19mm steel ball. The metal ramp with loop features a net at the end of the loop to…

Explore the basics of navigation and orienteering with this easy-to-use compass. Product features a sight finder, as well as markings in both the metric and English scales. A detachable lanyard is also included. Map scale is displayed in mm with a ratio of 1:25000. Dimensions: Thickness when…

This Ballistics Car demonstrates the independence of vertical and horizontal motions. It consists of a four-wheeled cart carrying a vertical tube with a spring-loaded piston inside. The tube is loaded with a ball and the cart is set in motion. During the motion, the piston is released remotely by a…

The Loop-The-Loop demonstrates the transformation of potential energy into kinetic energy in a fun and interesting way! Challenge your students to calculate the minimum height that the steel ball can be rolled down the track and still complete the loop without breaking contact with the track.

Features a sturdy carriage made of high impact plastic. The one piece needle bearing wheels allows the carriage to roll with little resistance; a hole in the plastic body allows you to attach a cord. The approximate size is 5.5 x 2.5 x 1.5 inches.

The Holding Rod for the N-00012 Speed Measurement Photogate is a specially designed adapter or holder with an extension rod. The holder allows you to secure the photogate to any stand at any desired angle or height. It will ensure success in whatever experiment you wish to carry out with a slope,…

The Photogate provides a simple, instant, and direct measurement of speed without the need of a connection to another device such as a computer or data logger. The BeeSpi V Photogate uses advanced light gate technology to measure, speed, lap time, and cumulative lap time with using one timer. By…

The balancing bird is a great demonstration of gravitational force, center of gravity and equilibrium. The birds weight is distributed on the tips of the wings and the mass is near the tip of the birds beak which holds the bird in a stabilized equilibrium.

The Magdeburg Hemisphere is a modern take on the famous 17th century experiment. With the Magdeburg Hemisphere, you can demonstrate the force of air pressure without a vacuum pump. When the two cups are pressed together, the air is evacuated, and a vacuum is created. Separating the discs will be an…

The ring and disc both have the same diameter and mass. Roll them down a slope to observe the variation in acceleration between the two. This set is use to teach the relationship between moment of inertia and distribution of mass. Includes instructions.

Drilled for lab demonstrations Approx. 2.5mm drilled hole 1" Hardwood Ball 1" Drilled hardwood ball - can be used for collision and pendulum demonstrations. Hardwood ball can be used for hobbies and various other things. Approx. 2.5mm drilled hole

The experiment demonstrates the same rate of fall for objects of different masses. The plastic cylinder has rubber closures on the ends. One end has a hose connection that is used to evacuate air. The coin (guinea) and feather fall simultaneously because air resistance has been removed.
