Description:
This model acts similarly to the Rabinion planetary gear of a modern vehicle. The complex principles of a planetary gear are unlocked with the use of color coded discs. Blue is used for the internal gear. Green is used for the pinion gear. Yellow is used for the sun gear. This model consists of 3 forward speeds and 1 reverse speed. The instructor or student manually operates this unit by locking by locking down a specific part of the gear using a fixed pin. Changes in rotation are visible when adjusting either the sun, pinion, or internal gear. A nomenclature panel is included on the front of the model for reference. These items are made special to order and are not held in stock. Lead times are approximately two to three months. Freight charges may apply. Dimention: 27V x 30W x 24H cm; Weight: 3 kg

Description:
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 using one timer. By adding a second timer, acceleration can be calculated.

Description:
This colorful, graphically rich chart illustrates and summarizes what is now known about the history and fate of the universe.
Developed by scientists at the Lawrence Berkeley National Laboratory (Berkeley Lab) in collaboration with the Contemporary Physics Education Project (CPEP) and George Smoot, Nobel prize winner for 2006, the chart is crammed with information covering a broad range of cosmological topics.
The centerpiece is an evolutionary timeline that takes viewers from 10-44 seconds, when the universe was much smaller than a proton, to the current era, about 14 billion years later, when the visible universe contains 4 x 1011 billion galaxies.
Side panels provide short discussions on the birth, inflation and expansion of the universe, the cosmic microwave background and redshifts of distant supernovas.

Description:
The New York State Regents Examination in Physical Setting/Earth Science (Part D) consists of two components: a laboratory performance test and a written test. The performance test features three different stations of hands-on activities. Using the New York State Education Department guidelines for the 2009 Performance Test (Part D), Ward’s created cost-effective, convenient kits with everything you need to prepare for administering the test at each station. Students can create and examine the elliptical orbit of asteroids with Ward’s Station #3 Kit including a spool of cotton string, six sheets of cardboard, box of 100 push pins, six plastic storage boxes, six metric rulers, and six calculators — enough materials for six station setups. Call 800-962-2660 for a more detailed list of contents.
