What color is grape soda? If you pour it into a clear glass you can easily see it is purple, but that is usually not its natural color. Manufacturers add red and blue dye to the soda. The dyes mix together and you get purple soda. What if you wanted to un-mix the dyes, could you? Yes! In a chemistry laboratory, using a technique called column chromatography, you could separate the two dyes again. But what about at home, can you use low-tech supplies to do the same thing? In this science… Read more

Science Fair Project Idea
The oceans are a precious natural resource, part of Earth's carbon cycle. But what happens if the oceans absorb too much carbon dioxide? Many scientists are concerned that the increased absorption of carbon dioxide is causing them to become more acidic. What impact does that have on the marine life? In this ocean science fair project, you will demonstrate ocean acidification and investigate the effect on the shells of marine life. Read more
