2. Mixtures and Solutions
OLS Lessons to be completed by next Tuesday: Unit 2 Lessons 1-4
Mixtures and Solutions
Solvents and Solutes
Separating Solutions
Dissolving Solutions
* You may have time to work on these assignments in class today.

3. Lesson 1: Mixtures and solutions
Big Idea #1
A SUBSTANCE is anything that contains only one kind of molecule.

4. Lesson 1: Mixtures and solutions
Big Idea #2
A MIXTURE is a combination of 2 or more substances that maintain their individual properties and DO NOT go through a chemical change when mixed.

5. Lesson 1: Mixtures and solutions
Big Idea #3
A SOLUTION is a mixture in which the substances are completely and evenly mixed down to their individual molecules.
- solutions can be made from combinations of gases, liquids, and solids

6. Lesson 2: Solvents and Solutes
Big Idea #1
A SOLUTE is a substance that dissolves in a solution.

7. Lesson 2: Solvents and Solutes
Big Idea #2
A SOLVENT is a substance that dissolves in a solute to make a solution.

Evaporation
Chromatography
Distillation

11. Lesson 3: Separating solutions
Big Idea #1 – Evaporation
Evaporation is great for separating a mixture (solution) of a soluble solid and a solvent. The process involves heating the solution until the solvent evaporates (turns into gas) leaving behind the solid residue

12. Lesson 3: Separating solutions
Big Idea #1 – Chromatography
This method is often used in the food industry. It is used to identify chemicals (coloring agents) in foods or inks. For example, if a scientist wants to know how many substances are in a particular blob of ink, paper chromatography can be used

13. Lesson 3: Separating solutions
Big Idea #1 – Distillation
This method is best for separating a liquid from a solution. In a way, the concept is similar to evaporation, but in this case, the vapor is collected by condensation. For example, if you want to separate water from a salt solution, simple distillation would be great for this.

16. Type your answer in the chat box!
REVIEW TIME!
Type your answer in the chat box!
How could you increase the rate of lemonade powder dissolving in water?

17. Raise your hand to be given the microphone!
If you cut up a piece of paper or boil a pot of water, a physical change has occurred. Would this also be considered a chemical change?
Defend your answer: WHY? or WHY NOT?

18. Use the polling tool to answer the question.
Juice, iced tea, and soda are all examples of what?
A solvent
A mixture
A solution
all of the above

19. Kahoot Review Time 8 Questions

20. Use this time wisely! = I need help or have a question. = I finished!
Today you will be working to complete any of your unfinished Science Lessons #1-7.
