Partial Pressure
At some point, everyone has been under pressure—even Dalton! Explore Dalton's law of partial pressures with young chemists as they measure the volume of air extracted from a sample compared to its original volume. Class...
Curated OER
Molar Mass
Students apply the ideal gas law and Dalton's Law of Partial Pressure to develop an experiment which determine the molar mass of butane from disposable lighters. In small groups, they develop a procedure and have it approved before...
Curated OER
Now Take a Deep Breath
Students research to answer questions related to deep sea diving. In this deep sea diving lesson, students answer questions on a worksheet using the Internet. They discuss pressure, gas laws, and the physiology of diving in the deep sea.
Curated OER
Now, Take a Deep Breath
Students define several laws of pressure and see how they relate to scuba diving. In this ocean explorer lesson students answer questions and complete an activity.

Serc: Making Hydrogen Gas From a Decomposition Reaction
A very simple reaction of acid (HCl) and metal (magnesium) to produce Hydrogen gas and metal salt will provide the volume of gas to evaluate. Students will determine the amount of gas produced at room conditions and then using the...
