Explore the chemistry and history of gases using this innovative and exciting hands-on approach to generating and using gases. Generate microscale quantities (40-50 mL) of 17 different gases using simple, readily available materials-plastic syringes,...

Colorless, odorless, tasteless-the chemical and physical properties of many gases make them invisible to our senses. But we know they exist because gases have properties we can test. Some gases are lighter than air. Other gases are flammable. While o...

Why are fish jumping out of the water in the heat of summer? Without a critical supply of dissolved oxygen, fish and other aquatic organisms would not survive. How do environmental factors such as temperature affect the level of dissolved oxygen? In ...

Learn Boyle's Law in a safe and environmentally friendly manner! More than 350 years ago, Robert Boyle used trapped air in a glass tube above a column of mercury to study the relationship between the volume and pressure of air. In this activity, stud...

Generate microscale quantities (50-60 mL) of carbon dioxide gas in syringes and observe the properties and reactions of the gas. Perform the classic lime water test for the detection of CO2, observe the acidic nature of the gas, watch the gas undergo...

Safely observe the explosive nature of hydrogen gas! Generate microscale amounts (50-60 mL) of hydrogen gas in syringes. Perform the classic candle test for the detection of H2, ignite bubbles filled with pure hydrogen and compare to bubbles filled w...

Oxygen-we need it to survive! Learn how O2 is prepared and observe some of its interesting properties. Generate microscale amounts (50-60 mL) of O2 gas in syringes by performing a catalytic decomposition reaction. Observe how oxygen supports combusti...

Student equipment kit is designed to accompany any or all of the Flinn Chemistry of Gases student laboratory kits. One equipment kit contains enough reusable materials for 15 lab groups. Students safely generate microscale quantities of gases in syri...

Perform a multitude of simple, hands-on classroom experiments to investigate the properties of gases without using any expensive equipment. The mercury-free pressure gauges, stopcocks, and syringes are easy to set up and give accurate and reproducibl...

Use the gas laws to learn the gas laws! The amount of gas needed to fill a container-whether it's an airbag or an airship-can lead to a lot of interesting discussion. The purpose of this microscale experiment is to determine the volume of one mole of...

Remember eating Pop Rocks®? What makes the candy crackle as it pops in your mouth? In this lab activity, students will dissolve a known mass of Pop Rocks in a tube filled with water and measure the volume of carbon dioxide gas released. The ident...

Hydrogen gas is prepared and tested more safely using microscale techniques. Hydrochloric acid reacts with zinc metal to produce hydrogen gas. The hydrogen gas is collected by water displacement in the bulb of a Beral-type pipet. Pure hydrogen gas as...

The properties of gases and the gas laws are important in many areas of science and real life, including physiology, meteorology, scuba diving, even hot air ballooning! In this activity-stations lab, students will investigate the properties of gases,...
