Evaporative Cooling

Students use a temperature sensor to determine the evaporation rates of different compounds and use the Molecular Model Set to help relate differences in rates to molecular composition and intermolecular forces.

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

Molecular Model Kit

Molecular Model Set

An ideal set for introductory chemistry. All the components needed to create simple to complex molecules.

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.
