We just learned about the element Obsidian

Another chemical element is Magnesium, called "Mg" for short on the Periodic Table.

Magnesium is a metal that is very common on our planet.
It is also in our bodies, and is used a lot to help plants grow.

One of the most interesting things about magnesium is that you can light it on fire.
It can even stay burning if it is underwater!

Since it burns so well, it is used a lot in fireworks, and even the metal sparklers that you light up for the 4th of July.
