It's Freezing!

There's definitely something goofy with our weather. It's snraining (TM) out and for some reason I'm thinking, "Ugh, I thought we were done with that." I live in Buffalo! We're supposed to have snow in February!

I don't care what the calendar says, we're starting spring next month around here. Before we do, I have one last wintertime science play project.

To finish up our little segment on melting and freezing, we made some ice cubes.

And because no science project is complete without food dye, we made colored ice.

We made ice from hot water and cold water. Not much difference, huh?

But when you see it with the dye, there was a huge difference:

The ice cube on the left was made with cold water; the right hot water.

All of them made a mess when melting.

After we made our ice cubes, we did one last experiment: an ice cube race!

We put two ice cubes on a dry cloth and some ice cubes in a bowl of cool water. We set the timer to see how long the ice would take to melt and which ice cubes melted first.

Answer? The ice cubes in water melted in six minutes, while the dry ice cubes made it for more than 20 minutes. Then we ate them. In the name of science.
