What: Earlier this summer we learned about density. Density is the amount of mass in a given volume, or amount of space. Mass is dependent on the number of molecules in an object. Objects that are ...

More than a century after the Titanic sank, engineers still have hopes of someday creating "unsinkable" ships. In a step toward reaching that lofty goal, researchers at the University of Rochester's ...

Host Lloyd Liedtke guides students through hands-on experiments exploring buoyancy, balance and force. Learn why some objects float while others sink, how paddle boats move, and how weight and volume ...

Darwin’s “seed salting” experiments were aimed at determining, first, how long seeds might retain their vitality after exposure to saltwater, and second, how long they can float versus sink in ...

Adam Sherwinski shows ciLiving host, Jaclyn Friedlander how to make a 3-layer float to test the density of each liquid In this fun and easy science experiment, we’ll show you how to make a three-layer ...

GRAND RAPIDS — What is density? Why is it important to us? In a previous experiment we learned about buoyancy with an orange sinking or floating and now we are going to learn about density with an egg ...

Pans of water sat on the tables of Granite Quarry Elementary’s media center. Objects such as golf balls, candles, spoons and straws patiently waited to be tested for buoyancy. And 20 smiling children ...

Students will be able to explain that the density of a substance has to do with how heavy it is compared to the size of the object. Students will also be able to explain that density is a ...
