It's a Gas!

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...

Although it was published in the year 2000, this chemistry assignment is ideal for practicing the application of Charles' law. There are seven real-world problems to solve, and plenty of space provided for doing so. Add this to your...

It doesn't matter how old you are or where you live, you can help protect the environment. Created in 2005 for World Environment Day, the agreement shows that the simple steps one can take to make a change have stayed the same, despite...

Explore structures within the realm of gas exchange in terrestrial and aquatic life.  The excellent, labelled diagrams and clear descriptions help your students view the different structures and adaptations that have developed. The 29...

The need for a respiratory system in humans versus being reliant on gas exchange structures is demonstrated. There are many details about the advantages and disadvantages of each mechanism.  Students are able to learn about the...

Can you crush a soda can using only the air around you? Use an engaging video to teach about the relationship between pressure, volume, moles, and temperature of a given gas, all done with the Ideal Gas Law.  

The Ideal Gas Law isn't always ideal. Learn about situations where gases behave differently and calculate those changes by using van der Waals' equation.

The Hindenburg and its use of the highly flammable gas hydrogen, used to keep it afloat, eventually caught fire and killed 36 people.  Use the Ideal Gas Law through analysis of the Hindenburg and discover why scientists chose hydrogen...

A problem from a chemistry textbook is posed on the screen. Sal solves the problem which attempts to calculate vapor pressure using the Ideal Gas Law. The rate of evaporation of water given a certain volume, temperature, and pressure is...

Beginning with a general discussion about natural gas, methane, and hydrocarbons, a few videos and diagrams are projected to support the lecture. Individuals participate in a brief activity by drinking juice through a straw, and then...
