DEMONSTRATE THE DIFFERENCES IN TEMPERATURE DENSITY, THROUGH A FUN EXPERIMENT. CAITLIN: TODAY WE ARE TESTING CONVECTION USING COLD WATER OR AN ICE CUBE DIED BLUE. WARM OR HOT WATER DYED RED AND ROOM ...

This experiment demonstrates how water at different temperatures has different densities, creating beautiful layering effects. You'll see how warm and cold water interact and learn about density ...

In physics, chilling out isn’t as simple as it seems. A hot object can cool more quickly than a warm one, a new study finds. When chilled, a warmer system cooled off in less time than it took a cooler ...

It sounds like one of the easiest experiments possible: Take two cups of water: one hot, one cold. Place both in a freezer and note which one freezes first. Common sense suggests that the colder water ...

Decades after a Tanzanian teenager initiated study of the “Mpemba effect,” the effort to confirm or refute it is leading physicists toward new theories about how substances relax to equilibrium. It ...

The story goes that in 1963, Tanzanian high school student Erasto Mpemba was making ice cream with his class when he impatiently put his sugar and milk concoction into the ice cream churner when it ...

The researchers found that a slightly curved meniscus allows more wave energy to pass through the barrier. Conversely, if the meniscus curves more steeply, it reduces the energy transported by the ...

WXMI — In our science experiment today, we look at a disappearing coin trick, which really is no trick at all. It illustrates density and refraction. Some things are more dense (or heavier) than other ...

A long time series of data simulated by the NCAR Community Climate Model is used to empirically determine the effects of imperfect spatial and temporal sampling on estimates of the model's global-mean ...

Aims Ingrowth bags are widely used to estimate mycorrhizal growth and dynamics. However, it remains unclear to what extent they reflect the surrounding soil, and how this varies with environmental ...
