1. Investigation 3 What is concentration?

3. Soft-Drink Investigation It’s party time… Our first challenge will be to find out how much powder I should mix with 1000ml of water to make a good-tasting drink. Is the soft drink a mixture? Is the soft drink a solution? How could you test to determine if it is solution?

4. Soft-Drink Investigation How would you know if you had made a saturated soft-drink solution? Lets take a look at solutions 1 and 2 List all the ways that solutions 1 and 2 are the same and different. Ingredients, appearance, and taste. 1 2

5. Soft-Drink Investigation Concentration Which soft-drink solution tasted sweeter? When a soft-drink solution tastes sweet (and looks dark), it is a concentrated solution. When it tastes weak (and looks light), it is a dilute solution.

6. Soft-Drink Investigation Lets take a look at solutions A and B A B

7. Soft-Drink Investigation Concentration refers to the amount of material dissolved in a measure (volume) of liquid. The more material dissolved in a given amount of liquid, the more concentrated the solution. What happens to the soft-drink solution when you increase the amount of powder in a given amount of water?

11. Investigation 3 Part 2Salt Concentration How do you make a concentrated soft-drink solution? A dilute soft-drink solution? How can you tell which of tow soft-drink solutions is more concentrated? What are some other solutions that vary in concentration?

12. Investigation 3 Part 2Salt Concentration Today we are going to investigate the concentration of salt solutions. But there’s a problem, we are not permitted to taste salt solutions, and they are colorless. How can you determine which salt solution is more concentrated? Can you use a balance to determine concentration?

13. Investigation 3 Part 2Mystery Solutions Do these three solutions have different concentrations? In your groups, you will plan a step-by-step procedure for solving the concentration mystery. Your going to write your plans in your journals.

14. Investigation 3 Part 2Mystery Solutions Getters #1 get three cups Label the cups by their color Transfer 50 ml of each solution into a labeled cup. Let the sleuthing begin!! What did your group decide??
