Combining physics and art, the pendulum wave demonstration uses kinetic energy to create a beautiful art display. The simple pendulum, at rest and in motion, demonstrates how a mass accelerates (and decelerates) in response to gravitational force. Multiple pendulums, with decreasing string lengths, in motion will simultaneously create changing visual patterns that mesmerize as they move in and out of sync with each other. The pendulum wave demo consists of a large acrylic frame and nine pendula with 1" steel balls, as well as an initiator stick to simultaneously release all pendula. Great product for the classroom, as a gift, or as a display piece. Assembly required. Comes in colorful retail ready packaging! Set-Up Instructions and Teacher's Guide included. Guide included encourages critical thinking and problem solving. Activities in Guide are great for STEM education and follow Common Core and National Next Generation Science Standards.

New & Improved! Now with longer battery life, upgraded electronics, and battery pull tab to preserved battery life. No other energy ball on the market with these upgraded features! The Energy Ball is a great way to demonstrate for kids how to conduct electricity in a circuit. The ball contains two small metal electrodes that when touched simultaneously, cause the ball to light up. Comes with a Teacher's Guide and reproducible Student Handout. Retail ready colorful blister packaging.

The Shinco Scope needs only available outdoor light or minimal room light. This eliminates the need for lamps, cords and mirrors. There are no knobs or gears, so there is no need to fuss with adjustments. The total magnification is (30x) along with reflective light capabilities allows you to view the exterior of 3-D specimens, printed matter and other ordinary objects. It also has a prism illuminator that sends transmitted light up through the stage allowing you to view the internal structure of thinly sectioned specimens. Great for kids and outdoor use. Locked on Eyepiece; Locked on Stage Clips; Nickel Plated Brass Tube; Corrosion Resistant Finish; Vinyl Cover; Lifetime Warranty.

New model with adjustable mount and viewing platform. This microscope gives you easy access to a close up view on common items around the house or the creepy crawlies from your backyard. The hand held aspect lets you manipulate the microscope to view just about anything you may wish. It also comes with a adjustable handy stand making viewing items of many sizes a snap as well. It is easy; one touch focus wheel makes the magnifying power of up to 200X simple to control. This Microscope conveniently allows you to capture your view by still image or video with the press of a button.

This self contained unit allows students to measure and study refraction of light. The angle of incident and refractive rays are easily seen with the help of a built-in laser as its light source. Add water up to the tank's midline and create a surface that precisely transmits and reflects the laser beam for student observations. The laser revolves around the circular graduated scale and can be set at any point. Students can easily observe light rays as they travel from air into water, water into air, and water into water. Circular scale is 6-38" (162mm) diameter. You can also detach the apparatus from the tank to perform refraction and reflection experiments with the included prisms and mirrors! Full kit contains 4 prisms, 2 mirrors, and laser.

To provide external magnetic field where required and to change the rate of magnetic flux passing through a coil. Consists of a plastic spool with windings of insulated copper. End plates have brass binding posts. Capacity 10 amperes when used intermittently and 5 amperes when used continuously. RoHS Certified. Specs: Number of turns per layer: 77+ Total number of turns: 550-570 Wire Gauge: 16 Capacity: 10 Amps If used intermittently, and 5 Amps continuously Core ID 5.5cm (about 2.5")

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. Sold as a set of two; approx length: 20" (500mm) and 30" (750mm). Comes with a Teacher's Guide with detailed instructions and a bag of crushed rosin to lightly coat your fingertips.

This Stereo Microscope is a great tool to use for studying specimens of large objects under low magnification, such as minerals, insects and plants parts. Top lighting, as in this Stereo Microscope, is the most effective way to illuminate light onto the object. It allows the light to reflect upward from the opaque surface of the specimen. Stereo Microscopes can be used to show greater specimen detail during a dissection. The Stereo Dissecting Microscope has standard "rack and pinion" focusing, allowing you to focus by turning the knob to slide the head of the microscope up and down. Features * Sharp stereo erect image over a wide field of view * Upright binocular head * The interpupillar distance is 2-18" to 3" (55-75mm) * Eyepiece: WF10X, Objective 2X * Working distance: 2-34" (70mm) * Built-in incident light or LED light * Plastic body, easy to carry * Uses 2 AA batteries (not included) * Packed in Styrofoam inner box
