Why Do Hot Air Balloons Float?

Using helium as an example of propane, physical science middle schoolers experiment with and graph the relationship between temperature and volume in gases. In a whole-class demonstration, they show how molecules behave under different...

A series of attention-grabbing demonstrations and lab activities is outlined in this document. Through them, chemistry kids appreciate the behavior of gases. Inflate balloons, marshmallows, and toothpaste tubes without adding air! Use...

A physical science presentation begins with an explanation of ideal gases and their behavior. Then it introduces all of the gas laws with descriptions and formulas. 

Pressure and volume remain inversely proportional for all gases. Socratica presents a video about this relationship as part of their chemistry playlist. It explains Boyle's Law and the associated formulas before demonstrating the...

[Free Registration/Login Required] In this interactive activity, discover the relationship between pressure and volume. After the activity, answer one challenge question about the topic.

[Free Registration/Login may be required to access all resource tools.] Boyle's law and the relationship between the volume and pressure of a gas.

This online calculator allows the student to solve for either Pressure or Volume. Other features include a tutorial explaining Boyle's law.

Colorful animation outlining the relationship between the temperature and volume of gas particles. See what happens when the number of particles and pressure remains constant and the temperature of the gas is altered.

Students determine the validity of Charles' Law. In this Charles' Law lesson plan, students measure the volumes of a gas at two different temperatures. They determine the volume at a high temperature and predict using Charles' Law what...
