State Changes

Students predict the shape of a phase change diagram for water when it moves from the solid to liquid to gas phase, then use a temperature sensor to construct a phase change diagram supported with data.

Supports NGSS Performance Expectation HS-PS1-3: Plan and conduct an investigation to gather evidence to compare the structure of substances at the bulk scale to infer the strength of electrical forces between particles.

Featured Equipment

Electrode Support

Electrode Support

Ideal for keeping sensors in place during experiments, this support connects to standard ring stands with an adjustable screw.

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.
