Measurement & Density

Ask your students if air/gas has mass and density. Surprise them with these demonstrations on measurement and density of not only air, but many other items as well.

Finding the Density of Air

Finding the Density of Air demonstrates how to determine the density of air using Archimedes Principle and a balloon filled with dry ice.

Alternate Text

Air Has Mass answers the question of whether or not gases have negative mass using the reaction of baking soda with vinegar in a closed bag.

Alternate Text

Finding the Density of Air

Archimedes’ principle and the density of air are difficult concepts for many students to understand. This simple demonstration uses a balloon filled with dry ice to illustrate the buoyancy of air and determine the density of air.

Air Has Mass-Density of Air

Abstract concepts such as Archimedes’ Principle, conservation of matter, and gases have mass can be difficult ideas for students to grasp. This series of demonstrations will help solidify students understanding.

The Floating Bowling Ball

Why do some things float while others sink? Capture your students’ attention with this eye-catching demonstration of a bowling ball floating in water!

Alternate Text

Density Challenge

Demonstrate your mastery of density by determining the maximum amount of sand that can be placed in a plastic vial and still allow the vial to float in water. Calculate the amount carefully—you only get one chance!

Determining the Amount of Air in the Classroom

How can the amount of air in the classroom be measured? Will measuring the volume of the container (the classroom) provide the best value for the amount of air? Would measuring the mass of air be more appropriate? Does air have mass? Let’s find out.
