Diffusion Through Balloons

Students conduct a series of experiments to observe factors that impact molecular movement. In this molecular chemistry lesson, students drop food coloring in water with different properties (hot, with ice, with alcohol) and observe how...

Students discover that warm air takes up more space than cold air.  In this science lesson, students perform 4 experiments using balloons to determine that the molecules of warm air are more spread out than those of cold air.

In lab groups, young scientists place aluminum cans with a bubble-solution cap into different temperatures of water to see what size of bubble dome forms. As part of an atmosphere unit in preparation for learning about convection...

Scientific inquiry activity where students investigate how molecules move in liquid. They will observe that molecules in liquid move in a random manner and that heat will increase and cold will decrease the speed of molecular movement in...

Students conduct an experiment to discover what happens to air when it is heated or cooled, discover that wind moves from a high-pressure area (an area of sinking air) to a low pressure area (an area of rising air).

Young scholars 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...

Learners explore the concept of air density. In this air density lesson, students fill balloons with helium and carbon dioxide. Learners determine which gases are heavier or lighter than air.

Students examine how a pollutant recovery method functions in cleaning industrial air pollution. They listen to a teacher-led discussion, conduct an experiment with balloons, static electricity, and pepper, and observe and record the...

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

Fourth graders observe, measure, and record data on the basic elements of weather over a period of time (i.e., precipitation, air temperature, wind speed and direction, and air pressure). Then, they make a barometer and keep record of...
