This document is a lesson about the building blocks of matter. It discusses key concepts including elements, atoms, compounds, and chemical changes. The objectives are to understand what a magnet is and its properties, that elements are the building blocks of matter, and how to differentiate between physical and chemical changes. Elements are the purest form of matter and can combine to form compounds with different properties than the original elements.

• Water can break apart into 2
gases( hydrogen + oxygen) both
of these gases are elements.
• H2O = 2Hydrogen + 1 Oxygen
• Wood when heated, it gives off
carbon gases, so carbon is
element but wood isn’t.

compounds.
Forms when you put 2 or more
elements together.

chemical change.
• Changes in the matter itself.
• You start with one kind and end
with another.
