Investigating Physical and Chemical Changes of Matter

Students use a variety of sensors and particle modeling to characterize physical and chemical changes of matter.

This lab uses a variety of methods to teach the difference between physical and chemical changes of matter at the intramolecular level. This understanding is reinforced using particle models of what happens to atoms and molecules during these changes.

Featured Equipment

Wireless Conductivity Sensor

Wireless Conductivity Sensor

This waterproof sensor connects via Bluetooth® to measure both conductivity (ionic content in solution) and total dissolved solids.

pH Sensor

Wireless pH Sensor

Here’s the best tool for measuring pH since litmus paper. The Wireless pH Sensor connects via Bluetooth® to monitor the pH of solutions.

Pressure Sensor

Wireless Pressure Sensor

The Wireless Pressure Sensor accurately and consistently measures absolute gas pressure.

Temperature Sensor

Wireless Temperature Sensor

The Wireless Temperature Sensor is a general-purpose sensor found in many science labs. With a rugged, waterproof design, and long-lasting battery, students can spend more time collecting data and less time dealing with equipment.

Many lab activities can be conducted with our Wireless, PASPORT, or even ScienceWorkshop sensors and equipment. For assistance with substituting compatible instruments, contact PASCO Technical Support. We're here to help.
