"micro tube racks"

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.

Helmholtz coils are used to produce a homogeneous magnetic field. Experiments on induction and electron deflection can be performed with the Rotary Frame with Flat Coil and the Fine Beam Tube. The coils can be used in parallel or in series and feature a spring clip on the cross bar to mount a Hall Sensor for measurements of the magnetic field. The maximum field strength generated by the coils (~ 4 mT) is approximately 750 times weaker than that produced by an MRI machine (~ 3T), which are known to be safe for use by people with medical implants such as pacemakers.

This apparatus is used to Verifying the Boyle’s law when air is decompressed and compressed. A horizontally mounted acrylic tube having a graduated scale (0- 300cm3) along one side. A gas tap closes the tube. Pressure gauge is present next to gas tap. By changing the position of rubber stopper, the effective length of the tube can be selected. The scale measures volume and pressure by means of pressure gauze. Boyle’s law is investigated by changing position of the stopper.

Add some student imagination and easily gathered items and students can start investigating pulleys and gears.

This easy-to-build hydraulic arm demonstrates the power of fluid dynamics.

The KidWind Motor Mount Pack holds the motor (generator) in place when affixed to the wind turbine nacelle. The Motor Mount Pack can be used to replace lost parts from a nacelle. It can also be used to mount a nacelle to the tower for a vertical axis wind turbine configuration.

The simpleGEN is an easy-to-build AC generator that allows students to explore the basics of electrical generator design.

The Solar Thermal Exploration Kit is modeled after a domestic solar water-heating system. Explore variables such as box color, light intensity, tube design, rate of water pumping, and amount of time it takes to heat the water. Learn about what makes a solar water heating system more or less efficient.

Evaluate structure and material strength.

Allows the Dual-Range Force Sensor to be mounted on the end of an air track for collision studies. Compatible with most air tracks distributed or made by PASCO scientific, Central Scientific, or Daedalon Corporation. Includes two magnetic bumpers.

The Lenz's Law Kit investigates how much force an induced magnetic field can create.

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