Science Talent Development

Today for Science Talent Development we were looking at solids, gases and liquids. First we did an experiment where we had three ice cubes. One of them was just plain frozen water. The other two were frozen sugar water and frozen orange raro. We put them in a petri dish each and checked up on them every three minutes to see which was melting the fastest. It turned out that plain and sugar water ice cubes melted the fastest. The raro ice cube melted the slowest because the raro was holding all the water together and not letting go.

We did another experiment after that. This one was the same except instead of having different kinds of ice cube, we had three plain ice cubes,  one without anything on it, one with salt sprinkled on top, and one with sugar sprinkled on top. The one with salt on top melted the quickest, because the salt is kind of like an acid.
