Elements, Compounds and Mixtures lets you create pictures showing the atoms in substances.

You’ll use it to:

• Show how elements are made of one type of atom.
• Explain that different elements are made up of different atoms.
• Show that atoms rearrange in chemical reactions.
• Show how compounds are made of atoms combined in a fixed ratio.
• Demonstrate the differences between pure substances and mixtures.
• Create pictures of common mixtures such as air and salt water.
