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 ...

COLUMBIA, S.C. — In the theme of Easter this week, we’re going to do an experiment today in which we use eggs! We’re going to talk about density, which is an important concept in science and in ...

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 ...

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 ...

Build literacy skills while making predictions with this sink-or-float activity. It's fun to learn about new concepts in a hands-on way. This family does just that with a sink-or-float activity you ...

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 ...
