the junior high satu and unsatu

1. ACTIVITY 1. FILL IN THE BLANK Directions: Consider the context of the sentences inside the parenthesis to help you determine the correct word. Think about what word would make the most sense in each blank. A __________( solution, substance) has two components; the _________ ( solute, solvent) and the __________( solute, solvent). A component present in small amounts is called __________( solute, solvent) and the component present in greater amounts is called __________ (solute, solvent). The solute is the substance that is being ___________( dissolved, dissolving), while the solvent is the ___________(dissolve, dissolving) medium. Solute and solvents may be liquid, solid, or gas.

2. ENGAGE

3. SATURATED AND UNSATURATED SOLUTION

4. 0BJECTIVES A. Differentiate between saturated and unsaturated solutions through a hands-on experiment. B. Cultivate curiosity and wonder about the behavior of substances when they dissolve in solvents. C. Acquire proficiency in the skill of systematic observation, noting changes in solution properties, and recording data accurately during experiments.

5. ACTIVITY 2: Saturated vs. Unsaturated Solutions EXPLORE Let students to discuss the differences they observed. In the "Saturated Solution," what happened when they added salt beyond a certain point? How did the "Unsaturated Solution" differ? Discuss the concept of solubility and relate it to the experiment. Explain that a saturated solution can't hold more solute at a given temperature and pressure, while an unsaturated solution can. Summarize the differences you observed between the "Saturated Solution" and the "Unsaturated Solution."

6. Activity 3: SATURATED AND UNSATURATED SOLUTIONS Directions: We use solutions every day. People who wear contact lenses use “lens solution” to rinse their contacts and keep them wet. Athletes who consume sports drinks after exercising benefit from the electrolytes in those solutions. This activity will explore whether there is a limit to how much of one substance can dissolve in another. Write your answer on the table.

9. What best describes a saturated solution? A) A solution where no more solute can dissolve at a given temperature and pressure. B) A solution with a high concentration of solute. C) A solution with a low concentration of solute. D) A solution that is perfectly clear. 2. Which of the following factors can affect solubility? A) Color of the solute B) Temperature C) Container size D) Time of day

10. 3. In an unsaturated solution, what happens when you add more solute? A) The solute dissolves completely. B) The solute remains at the bottom. C) The solute forms a precipitate. D) The solute evaporates.

11. 4. Which of the following statements is true about the temperature's effect on solubility? A) Most solutes become less soluble as the temperature increases. B) Most solutes become more soluble as the temperature increases. C) Temperature has no effect on solubility. D) Solubility decreases in cold water and increases in hot water. 5. If you keep adding sugar to a cup of hot tea and it continues to dissolve until no more sugar can be added, what kind of solution is it? A) Unsaturated solution B) Saturated solution C) Diluted solution D) Concentrated solution
