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 ...

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 ...

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 ...

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 ...

KRISTI CRAVEN/ SALISBURY POST From left, Nicholas Jones, Daniel Wiles, Evelyn Phan, and Ty Snider open a bag of items for a science experiment at Science Days with Thrive on June 27, 2017 at Granite ...

Whether an object floats or sinks in water is determined by the ratio of its weight compared to its volume. If an object of a certain volume weighs more than an equal volume of water, it sinks because ...

Boats are such a part of our lives that we may not think twice about all the things that make them tick. We're more than happy to enjoy a ride over the water, but that's one of the more puzzling facts ...

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 ...

Floating is when something stays on top of the surface of the water, like a boat. Sinking is when something drops beneath the surface of the water and falls to the bottom, like a stone. Can you think ...

Beth Harris, Raleigh science educator, mom and author, is back with a fun holiday science experiment that will keep the kids busy. Beth Harris, Raleigh science educator, mom and author, is back with a ...
