The Microstirrer takes the place of the stirring bar that is typically used with a laboratory magnetic stirrer. The new Vernier Microstirrer easily attaches to the end of a pH Sensor, Conductivity Probe, Dissolved Oxygen Probe, or Ion-Selective Electrode. When the magnetic stirrer plate (required, but not included) is turned on, its magnetic field turns the paddle wheel of the Microstirrer, resulting in enhanced stirring near the electrode tip. The Microstirrer works with any magnetic stirrer.

Use the Time of Flight Pad to precisely measure how long a projectile has been in motion. The Time of Flight Pad is used with the Vernier Projectile Launcher and a Vernier interface to determine the launch speed of a projectile, along with the time the projectile is in flight. Time-of-flight measurements allow students to see just how kinematic calculations work in real-world applications. The Time of Flight Pad is electrically like a photogate. When a ball strikes the foam top surface, a circuit is closed.

The Vernier Resistor Board has seven 1 W 5% resistors mounted on a circuit board.

The Vernier Arduino Interface Shield plugs directly on top of the Arduino and adds two BTA (analog) and two BTD (digital) sockets. This shield was developed to be used with the SparkFun Arduino RedBoard but will work with the Arduino Uno and other Uno equivalents like the Leonardo. It also works with the Intel Galileo.

Measure the concentration of ethanol in air above an aqueous sample.

Study Newton's third law.

Secure your Go Direct® sensors for field work.

The simpleGEN is an easy-to-build AC generator that allows students to explore the basics of electrical generator design. With the simpleGEN, you can demonstrate Faraday’s law, light LEDs, and perform experiments that explore how coils, magnets, and rotation affect electrical generation. With some quick modifications, you will be able to convert your generator to a simple motor and explore additional variables. You can also take your experiments to the next level by converting your simpleGEN into a wind turbine nacelle.

Accurately measure the velocity of your dynamics cart.

The Motion Encoder Cart is a dynamics cart compatible with the Vernier Dynamics Cart and Track System. The Motion Encoder Cart replaces a motion detector when used for dynamics cart-on-track activities. An optical sensor beneath the dynamics cart senses the passage of the cart over a marked strip on the track. The position information is sent as an encoded IR signal to a receiver at the track’s end. By avoiding the possibility of stray sound reflections, this optical-only system provides excellent, repeatable, and noise-resistant motion data.

The High Torque Generator is another option for your wind turbine generator. When compared to the standard Wind Turbine Generator, this High Torque Generator will produce lower voltage but higher current for a given rotor RPM. The High Torque Generator is great for load devices with higher current draw, such as the water pump. This generator has the same 2 mm driveshaft as the standard Wind Turbine Generator, so the Wind Turbine Hub is interchangeable with either motor. The generator also has 4-foot leads with shrink-wrap reinforced soldering.

Collect quantitative acceleration data with this adjustable fan cart.

This adapter allows a Go!Temp or Go!Link* to connect to the USB port of a TI-Nspire handheld or TI-84 graphing calculator. The adapter has a USB standard-A receptacle which connects to the Go!Temp or Go!Link and a USB Mini-A USB plug that connects to the calculator. The adapter can also be used with the USB cable that comes with a Go!Motion.

The Digital Control Unit (DCU) makes it easy to use the digital output lines of an interface to control DC electrical devices.

Add the Vernier Optics Expansion Kit to your Vernier Dynamics System to conduct optics experiments, such as image formation with lenses and light intensity vs. distance. You can even use the kit to build a basic telescope.
