Gases Lighter and Heavier than Air

Young scientists learn that seeing isn't necessarily believing when it comes to the states of matter. After performing a fun class demonstration that models the difference between solids, liquids, and gases, children complete a series of...

Solids, liquids, gasses oh my!  Young scientists will be amazed when they try this experiment, which uses dry ice to discover the states of matter through sublimation.  

Clever! In order to compare indoor and outdoor dispersal rates for the movement of gases and particles through air, collaborators will participate in a classroom experiment. Set up a circular grid and set students on lines that are...

Scholars participate in two design challenges concerning flight in the second lesson of the series. They design balloon crafts that have neutral buoyancy and forward motion.

In class, your emerging environmentalists construct dust catchers. They take them home for a week or two, and then bring them back into class to examine under a magnifier. From this activity, they learn what makes up dust and that...

Plenty of background information about how air pollution affects much more than just our lungs is included on this attractive handout. After reading, pupils make a working model of a lung and diaphragm. Junior physicians place a small...

Don't lift another finger, this physical and environmental science unit has everything you need to begin teaching your class about energy. Starting with a look at the greenhouse effect, these lessons and activities take young scientists...

Give your class a colorful and tasty representation of the components of the mixture that we call air. Pop a few batches of popcorn in four different colors, one to represent each gas: nitrogen, oxygen, argon, and carbon dioxide. The...

This lesson certainly will not be a drag! Little engineers design parachutes that make use of air resistance and, as a result, slow the descent of the payload as much as possible. It is an opportunity to teach about many motion concepts:...

Young scientists know it is hotter along the equator, but why is it also rainier? Through the process of completing two experiments and a worksheet, scholars discover the answer is the intertropical convergence zone. First, they...
