But they shouldn't have a stray subject slipped in another category's field. The categories of information must relate. Atoms, the smallest known objects in our universe, make up the elements of which all matter is composed. Look at the Periodic Table of Elements chart on your science classroom wall or look up metals in a science reference source. Check out how many of the elements are metals.
Metals come from minerals found in the Earth's crust.
When combined with other materials, they add strength or conductivity. On their own, metals are very useful because they conduct heat and electricity. You probably think of gold first when someone asks you to name a metal. In this challenge, you will create a database of metals and verify that the data for the metals match the facts in the Periodic Table of Elements. Select a database software to use.
