We just learned about the element of Magnesium.

Another chemical element is Calcium, called "Ca" for short on the Periodic Table.

When you drink milk, did you know that you're also drinking some metal?
Calcium is a healthy ingredient found in milk, that helps us have strong bones and teeth.
You can't tell that it's metal because there's only a tiny bit of calcium in there, so little you can't even see it.

Calcium all by itself is a shiny gray colored metal.
