Take a peek inside a window to heat efficiency. Scholars watch a demonstration to investigate how heat dissipates from several different cups of hot water. They relate this to how heat escapes from the windows of a house. This the 14th...

Discover the process for extracting gases from the air. A 35-part lesson series continues with a discussion of fractional distillation. The instructor explains how to cool air to a liquid state and then slowly warm the air to collect...

Students experiment to observe air and its mass.  In this air lesson, students use the scientific method to complete experiments that demonstrate the properties of air. Students view a video as follow-up.

Students experiment with common substances to observe molecular behavior. In this molecular properties lesson, students move through four stations as they try to inflate a balloon inside a bottle, pour water from a jar, and observe how...

Students examine air pressure. In this air pressure lesson, students perform a series of experiments to evaluate the effects of air pressure.

Students explore air through guided discovery. In this air lesson, students will observe three demonstrations about air. They will answer leading questions as they observe how air displaces and takes up space, how air has weight, and how...

Pupils read a book and have a class discussion about the air around them. In this air lesson plan, students learn about properties of air, and discuss other gases they have observed.

Fourth graders conduct an experiment to get them thinking about the invisibility of air, and to prove that air has weight.

Students recognize that air has the properties of mass and volume. They predict, observe, and evaluate the effect of the air on various objects, using bubbles and bubble wands.
