*Full Lesson* Chemistry: Molecules, Elements and Compounds

This is the second lesson in a unit of work about atoms, elements and compounds. It is aimed towards KS3 but could be adapted for other levels. This lesson focuses on the difference between molecules of elements and compounds and compounds and their constituent elements.

During this lesson pupils will:

• Recap the structure of an atom from last lesson
• Define what a molecules is.
• Define what a compound is.

• Use the periodic table to identify if a substance is an element or compound.
• Investigate the difference between water, hydrogen and water and chlorine, sodium and salt.
• Identify that the properties of compounds are different than the elements that make them up.
• Conduct practicals to create iron oxide and copper sulfide.
• Watch teacher demonstration of making magnesium oxide.
