The properties of gases and the gas laws are important in many areas of science and real life, including physiology, meteorology, scuba diving and even hot air ballooning! In this activity-stations kit, students investigate the properties of gases, derive the mathematical relationships among the gas variables and use the kinetic-molecular theory to explain the behavior of gases. The four self-contained “mini-lab” activities each focus on a specific principle or topic:
- Diffusion of Gas Molecules
- Atmospheric Pressure
- Boyle’s Law
- Charles’s Law
Each activity takes about 10 minutes to complete—student groups may rotate through the stations in any order. Teacher Notes with complete sample data, comprehensive background information, reproducible student handouts and all chemicals and consumables needed to perform the activities are supplied. Do more labs in less time!
Complete for 24 students working in groups of three.

MS-PS1-2. Analyze and interpret data on the properties of substances before and after the substances interact to determine if a chemical reaction has occurred.
MS-PS1-4. Develop a model that predicts and describes changes in particle motion, temperature, and state of a pure substance when thermal energy is added or removed.
MS-PS3-4. Plan an investigation to determine the relationships among the energy transferred, the type of matter, the mass, and the change in the average kinetic energy of the particles as measured by the temperature of the sample.
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.
