A lab where the students study the density of pennies. They will discover the limitations of measurements and the value of multiple trials.
Why does an egg float in salt water? Learn about density and buoyancy in this video segment adapted from ZOOM.
Watch warm water float on top of cold water in this video segment adapted from ZOOM.
This video segment adapted from ZOOM offers a clever demonstration of buoyancy by showing how to pour a cup of air into a cup filled with water.
Will a grape float in oil? Will a metal nut sink in corn syrup? Watch as the ZOOM cast tests the buoyancy of a variety of liquids and objects.
This activity is a classroom experiment where students make observations, state hypothesis and carry out an investigation to draw conclusions.
This activity is a demonstration proving that carbon dioxide is more dense than air which leads to a deeper understanding of the term density.

In this video segment adapted from ZOOM, cast members design and build door alarms using a variety of materials, including aluminum foil, batteries, and buzzers.
In this video segment adapted from ZOOM, cast members discover that metal is a good conductor of electricity as they play the steadiness tester game.
In this video segment adapted from ZOOM, cast members make a bridge from a single piece of paper. Will it be strong enough to hold a hundred pennies?
This activity is a physics lab to detect a magnet's field.
In this video from NOVA scienceNOW, learn how scientists detect potential signs of life on distant planets.
This activity is an inquiry lab where students observe the effects of temperature change on nitrogen dioxide gas, a common component of polluted air, to determine its color.
In this field lab activity, students will determine the density, pH and water content of prairie soil, transition soil, woods soil, and riverbed soil and compare their findings.
