Study friction, simple harmonic motion, impact in collisions or centripetal force with this sensor.

The Geiger Muller Sensor is used in experiments such as demonstrating the random nature of radioactive radiation, measuring Activity vs. Distance of a radioactive source and investigating the effect of different absorbers on radiation. * Sensor design may change

Use this sensor to compare or monitor heart rates before, during and after brief vigorous activity and monitor the time it takes the heart rate to return to normal.

Use this high accuracy sensor to measure an individual’s fitness, and how factors such as level of activity, gender and size impact heart rate.

Using the humidity sensor, learn about body respiration properties, biotic conditions outdoors and research the meteorological connections between humidity and temperature.

Humidity and Temperature are not only a key part of many scientific experiments, they are quite commonly measured together. With the new einstein™ Temperature and Humidity sensor these experiments are now easier than ever. The Temperature sensor has a wide range (-40 °C to 125 °C) while the Humidity sensor measures relative humidity from 0-100 %.

This lead sensor easily measures the amount of lead in a solution and in soil. * Electrode also sold separately

The Light sensor contains a high precision Photoelectric cell that measure light intensity in activities such as solar radiation and photosynthesis.

The triple axis Magnetic Field sensor is able to measure magnetic fields along the x, y and z axes simultaneously. This Magnetic Field Sensor can be used for measuring a wide range of magnetic fields, from the Earth’s weak magnetic field to the strong magnetic fields inside solenoids – up to 20 mT.

This sensor is designed to study the properties of sound waves such as sound speed through air and other materials, sound beats or harmonic properties of sound.
