Physics Educational Materials

Description:   Apparatus for measuring the time it takes for a ball to fall a certain distance using a digital timer. Very easy to set up and use but nevertheless highly accurate. Includes 3 steel balls. A micro-magnet holds the ball in its start position. Three contact pins under the release mechanism ensure that the start position of the ball can be reproduced and act as the contacts of a switch that opens when the ball is released, thus triggering the beginning of the timing measurement. When the ball strikes the contact plate at the bottom, the timer is stopped. The ball is also held firmly on the plate so that it does not bounce. The height through which the ball drops can be adjusted to a fraction of a millimeter and read off a scale on the column.

Description:   Set of apparatus for carrying out 10 basic student experiments on radioactivity. In a robust Gratnell tray with foam inserts molded to the shapes of the items and a transparent lid. Includes a CD with instructions for the experiments. The experiments are designed to occupy as little space as possible on the supplied base plate, while remaining clear and easy to perform. To determine the count rates, it is recommended that a Geiger counter be used (not included).

Description:   For electrical circuits with low voltages and high currents; copper wire encased in highly flexible PVC; equipped at either end with a laminated safety plug and a fully-insulated axial jack for connecting additional patch cords.

Description:   Universally applicable, floating, high-voltage power supply with built-in, high voltage resistant transformer to supply the heater voltage for electron tubes. Continuously adjustable high voltage, safe to touch, with passive current limitation and analog voltage display. Unit poles can be connected to protected earth, but it is not center tapped.

Description:   All you need to add is a wind source, basic tools, and imagination!

Description:   These dowels are used for designing and testing wind turbine blades and fit into the Wind Turbine Hub.

Description:   This kit enables a number of advanced experiments, especially with GENPack generator module. Try different gear ratios, blade designs, generators, and more, in a creative, hands-on inquiry into wind energy science. This nacelle also converts for conducting weightlifting experiments, making it a great option for studying mechanical and electrical energy.

Description:   KidWind wind turbine generator with wire. Recommended for college, high school, and middle school science.

Description:   Investigate the deflection of electrons.

Description:   Dualism of waves and particles.

Description:   The adapter includes two connectors for Vernier analog sensors and one connector for Vernier digital sensors. A screw terminal and header pins provide access to myDAQ lines not used by the connectors. This includes the two analog output lines, three digital lines (including the digital lines with the frequency and pulse width modulation outputs), and a +5 volt power terminal.

Description:   Mounted on a wooden stand with a scale, the apparatus is comprised of a three-limbed glass tube with rubber tubing on the center.

Description:   This advanced ripple tank comes complete with all accessories needed for wave investigations.
Tank is intensely illuminated by a strong light source, and synchronized with the wave generator to help students observe the wave patterns on a workgroup table.
The frame is made of reinforced plastic and with foam beaches (to negate reflections). Includes a mirror, which can be mounted at 45 degrees, to project the ripples onto a translucent screen on one side of the unit.
Each water wave acts much like a curved lens. The crest of the wave is seen as a bright region and the trough is seen as a dark region. Inside the ripple tank is a mechanical vibrator attached to a wave generator that produces either point wavelets or parallel wave fronts.
Various obstructions and barriers can be inserted into the path of the wave, such as a single slit, a double slit, or an edge.
