See how easy it is to connect PASCO's new line of wireless sensors to SPARKvue for quick and affordable measurements in the science classroom.

Learn how to use the PASCO Wireless Spectrometer and free Spectrometry software to analyze the kinetics of the reaction of sodium hydroxide and crystal violet.

Learn how the Colorimeter and Spectrometer can be used to analyze the absorbance of light by pigments extracted from various leaves. We compare green spinach and purple plum leaves and discuss the relationship between absorbance and photosynthesis.

Overview of PASCO's SPARKvue 2 software for data collection and analysis in the science classroom.

Learn how to initiate a repair with PASCO's Teacher and Technical Support team.

We compare the capabilities of the PASCO Spectrometer and Colorimeter across these topics in chemistry:

• Analyzing Colored Solutions & Fluorescence [0:20]
• Concentration and Absorbance [3:13]
• Reaction Kinetics [6:22]
• Emission Spectra [9:43]

Learn how the new PASCO Polarimeter is used to measure the optical rotation of plane polarized light by chiral compounds.

Following a visual demonstration with the Polarizer Demonstrator and corn syrup, we use the Polarimeter to quantify the optical rotation of plane polarized light by a sucrose solution by determining the angle of rotation with the greatest intensity.

Learn about the many free services provided by PASCO's Teacher and Technical Support group.

Learn how to use the PASCO Wireless Spectrometer and Spectrometry software to perform a Beer's Law analysis of the concentration of a colored solution.

After calibration and selection of wavelength, we establish the relationship between the absorbance and concentration for standard solutions and then determine the unknown concentration of an unknown.

What ion causes the glow when high current is passed through a pickle? In this very special episode released for Mole Day 2014, we find out by analyzing the glowing light with the new PASCO Wireless Spectrometer.
