Today I have a fun ice boat science activity to do with kids to help teach them this concept. This would be a great activity to add to any physical science lessons. It would also make a fun summer learning activity! See also:Sink or Float: Density of Salt Water Why Does Ice Float?
Why do things float in water? Objects are made up of very tiny molecules. Molecules can be packed in close together like in a rock or more spread out like in bubble wrap. The positioning of molecules affects the density of an object. Objects with tightly packed molecules are more dense th...
Density for Kids Before we can understand why some things float and some don’t we need to understand density! Density is a measure of how close together these pieces are. If they are close together, the object is dense. If the pieces are far apart, the object is less dense as their ...
Why Do Ships Float -- Or Sink?The article presents science experiments to determine the factors governing the sinking or floating of ships, including buoyancy, displacement and excess weight.D'Alto, NickOdyssey
or hollow- or solid- does not affect its ability to float in water. What determines whether something floats or sinks in water? When an object enters water, it pushes out water to make room for itself. The object pushes out a volume of water that is equal to its own volume. This is...

For every mole of sugar the yeast expels one mole of CO2 (Carbonation) and one mole of alcohol. The yeast are also using O2 (oxygen) . O2, CO2, and alcohol are all lighter than water and become trapped in the cellulose produced by the bacteria. The bacteria uses O2 to convert alcoh...

Lots more people than you realize have stories about sleepwalking when they were kids — their parents found them wandering on the front lawn, or they walked down the street in their pajamas. Kids tend to grow out of it. The adult population of sleepwalkers is much smaller. Sleepwalking also...
