Do all liquids evaporate at the same rate? Young scientists observe the evaporation rate of three different liquids. They measure the time, the temperature, and the change in energy. After comparing the chemical formulas, scholars develop a hypothesis to explain the differences.

Instructional Ideas

• Use when studying phase changes, chemical/physical changes, or energy

Classroom Considerations

• Follow all safety procedures as some of the chemicals are flammable and require ventilation
• Only use glass beakers because one of the chemicals dissolves plastic

Pros

• Uses common scientific equipment
• Offers interpretation as well as reflection questions after the lab

Cons

• None
