Blue Team
Blue Team - Compare these graphs. explain which is a mixture and how you know.
Orange Team - Write a short paragraph, identifying and explaining the differences between a mixture and a compound
Tasks
Green Team - Complete the handout
The Temperature continues to rise on the mixture during change of state on graph Y due to different melting/boiling points
Blue Team - The Temperature continues to rise on the mixture during change of state on graph Y due to different melting/boiling points
Orange Team - Mixtures are a combination of different elements and compounds that are randomly distributed, Compounds are two or more elements that are chemically bonded together, can form a regular pattern
- Green Team -
• A Mixture is made up of different substances that are not chemically joined together.
- You can change the amounts of substances in a mixture (compounds).
- A pure substance has no other substances mixed with it.
- Compounds only contain two different types of substance. (Contain many/more than two)

Key Terms & Ideas
Mr Dawson goes to make a cup of tea. He pours sugar into the hot tea and stirs, what happens to the sugar?
Whats Happening?
Define
Define
The sugar Dissolves in the Tea. The Tea is the Solvent and the Sugar is the Solute
Key Terms
Define
Dissolves - when a solid becomes incorporated (Becomes a part of) into a liquid. Usually by breaking down in smaller pieces
Solvent - a substance with the ability to break down other substances into a solution
Definitions
Solute - the minor part of a solution, dissolved by the solution

Recap on Modeling
Modeling Dissolving
Draw two Diagrams:
- Sugar in water/Tea
- Sugar Dissolved in water/Tea
Ext. Explain what is happening
Task
Dissolved
Did you know Gases can dissolve to?
Dissolving in everyday life
Can you think of where you might encounter this?
Carbonated drinks (Fizzy drinks)
Are the result of Carbon dioxide being dissolved into water.
Most also have Sugar and Flavorings Dissolved in as well!
