Teach Engineering: Air Is It Really There?

Determining whether or not something is living can be more difficult than it seems. Put your young scientists to work defining their own criteria to identify life, then work with three samples to see if they are alive or...

An experiment to explore the properties of air, using a cup placed upsidedown in water.

Humans aren't the only species to build structures with air conditioning—we weren't even the first! The video explains how a variety of species that live under and above ground design their structures to allow for air circulation. It...

Love is in the air? Wrong — nitrogen, oxygen, and carbon dioxide are in the air. The final lesson in the series of five covers the impact of temperature on gases. Scholars view a demonstration of gas as a type of matter before performing...

Investigate the relationship between temperature and pressure. Learners change the pressure of a sample of air and monitor its temperature. They learn that as air decreases its pressure, its thermal energy converts to kinetic energy.

Students explore the concept that air is everywhere. They assess that it can't be seen, but is all around us. Each student becomes aware that air takes up space and listen to the book, "Air is All Around You," by Franklin M. Branley.

An overview of engineering and design which introduces the students to the basic steps of the engineering design process. This lesson challenges students to plan a picnic for their friends by considering its various components as they go...

Students work together to perform simple experiments discovering the properties of air. They share their results with their classmates. They examine how engineers use the properties of air to clean the air of pollutants.

Students are introduced to the concept of air quality by investigating the composition, properties, atmospheric layers and everyday importance of air. They explore the sources and effects of visible and invisible air pollution. By...

Is it possible to create an environmentally friendly shampoo? Learners accept this challenge in the fifth lesson in a green chemistry series of 24. The analysis of their shampoo ingredients must address pH, exothermic reactions, and...
