Pasco PS-2147 Precision pH and Temperature plus ORP/ISE Amplifier sensor measure pH and temperature with the provided probe and with additional probes can measure oxidation reduction potential or ion concentrations in aqueous solutions.

Use this Quad Temperature Sensor to collect 4 different temperature measurements at the same time. Great for experiments with heat transfer and other cause and effect activities.

The PS-2195 Salinity Sensor calculates the concentration of salt in water by measuring the conductivity and temperature of the solution.

Measure the percentage of water in soil for environmental science, agricultural, earth science, and many other experiments. Great for use in the field, or even in your school courtyard!

This system is easy to use and includes a variety of safety features that make it suitable for beginning labs. Mount any of the 8 different spectral tubes into the power supply and turn it on. The 26 cm long tubes are capillary-thin over the middle 10 cm, providing sharp, bright spectra. This kit includes the 2 most common spectral elements in space (Hydrogen and Helium) and Neon for common classroom light source comparison.

The Pasco Turbidity Sensor measures the particles suspended in aqueous solutions in NTU (Nephelometric Turbidity Unit). The sensor can also measure precipitation or settling of suspended particles in a solution. Great for field studies or use with water filtration kits.

The Pasco PS-2149 Ultraviolet Light Sensor measure the UVA band (315 - 400 nanometers) and the visible spectrum.

Simultaneously measure the voltage, current, and power of a circuit. For safety, the sensor will automatically beep and shut down if the current is too high, and will reset automatically when the overload is removed.

The weather / anemometer sensor allows to measure multiple atmospheric parameters such as wind speed, air temperature, and humidity at a certain point.

Understanding pendulum motion is fundamental to the study of vibrations and waves. This unique United Science Supplies kit includes everything necessary for a full exploration of the basic features of pendulum motion in a complete but economical set. The individual components are of proven design - the drilled balls have a larger hole on one end than the other to allow suspension at the center of mass, and the triple support features clamps that make adjusting the cord length precise and easy. Students can assess the principal factors of mass, length, and amplitude and even venture into a consideration of air resistance.

With the PITSCO Structure testing machine students are capable to up to 800 pounds of force to structures including balsa wood or basswood towers and bridges using a turn-force wheel. Students can apply pressure in small increments and stop applying pressure at the first sign of structural damage--so they don't have to destroy the structure to test it to the limit. And because the system captures both the peak load and the current load, the load that 'breaks' the structure is displayed. Because the load reading is given at every change, students can follow a precise pattern to ensure consistent testing in a classroom setting.

The PocketLab G-Force sensor is a force and motion sensor on wheels. Measures velocity (speedometer), position (odometer), G-force (accelerometer), acceleration (accelerometer), rotation (gyroscope), and direction (magnetometer). The sensor connects via Bluetooth and is compatible with iOS, Android, Chrome OS, Windows 10, and macOS devices. The kit contains 5 PocketLab G-Force Sensor Cars, tracks, and accessories. Teachers have used this kit to engage students in a hands-on activity to learn about Newton's laws. Look for sample activities in the resources for this kit.

The turbo track kit is a fantastic expansion kit for the PocketLab Sensor and G-Force kit that is perfect for anyone interested in Newton's laws and physics experiments.

With this kit, our teachers can easily conduct experiments using the sensor on cars and tracks, allowing you to explore the principles of motion, acceleration, and force.

This kit is a great way to learn more about physics while having fun at the same time!

The kit includes everything you need to explore Newton's Laws of Motion.

The PocketLab Voyager Classroom Set is a force and motion sensor that measures velocity (speedometer), position (odometer), G-force (accelerometer), acceleration (accelerometer), rotation (gyroscope), and direction (magnetometer). The sensors connect via Bluetooth and are compatible with iOS, Android, Chrome OS, Windows, and macOS devices.

Teachers have used this kit to engage students in a hands-on activity to learn about Newton's laws.

The kit contains: 10 PocketLab Voyager Sensors, ten silicone cases, charging cables, a charger, and a plastic case to store everything.

The Bucket Orchid Pollinator Model was developed by STEM Pre-Academy as an engineering design challenge tool for teachers, and over time, it has been proven engaging and fun for the students.

Teachers have used this to teach students the importance of these pollinators and plant morphology while integrating the engineering design process to develop a hand pollinator.

With this model, students can test their different prototypes of pollinators in the classroom. Each kit includes one pollinator model and ten "pom-poms" to simulate pollen.
