In Vitro-In a Glass Container

This is what I did in Chemistry this morning! I just started the module yesterday so the experiments are pretty basic but still pretty cool.

In this one, we learned about density by measuring the mass of three different substances: corn syrup, water, and vegetable oil. Then we layered them in the glass (shown above). The layers stayed separated because of the different densities!

It was pretty neat. I'm liking chemistry a lot so far. In chemistry, you have a very specific way of measuring things and then you only use a certain amount of numbers (called "significant figrues") depending on the precision of the instrument you are using. Cool huh?
