Chemistry
Solids, liquids and gases
Solids, liquids and gases are all different things. They are all made up of something called particles. The particles in a solid are very compact. In liquids the particles are loose, taking the containers shape. Gas is a little similar to liquids because they also take the containers shape but, the particles are different. They fly everywhere.
Buoyancy
Buoyancy is the force that allows things to float. It is an
upward force that
that pushes against gravity. It is so well balanced that we are able to
float.
Join me next time on science kids doing biology,
until next time.
