1. A World without compounds

2. Learning Scale
Level 4 – Investigate and describe the compounds formed by bonding elements. Level 3 – Describe how elements combine to form compounds. Describe the motion of the particles in a solid, liquid, and gas. Level 2 – Use the periodic table to identify the number of protons, neutrons, or electrons in an element. Level 1 – Locate and identify elements on the periodic table.

3. Elements vs. Compounds

4. Think Pair Share
What happens to the properties of elements when they combine to form compounds?

5. Common Compounds
NaHCO3
Mg(OH)2
NaCl
C12H22O11
H2O
SiO2

6. Your Task
You have been hired to create a team that can win the annual element challenge. Each team member must be based on the same basic element but have different skills to ensure that your compound line-up wins!

7. Compound Line-Up Example
Write your element at the top
Find 4 compounds with Magnesium in it.
Magnesium (Mg)

8. A World Without Compounds Example
Write 2 uses for each compound.
Frame of Reference = 3 uses of your element
Magnesium (Mg)

9. Compound Line-Up Summary
Write a minimum of one paragraph (4-6 sentences) explaining how one element can combine to form many compounds. Be sure to explain how the properties of elements and compounds are different. Support your answer with evidence from your tree map.
