🎯 Part 1: Learning Target & Background Knowledge

1. Circle the "I can" statements that describe what you will learn today:

I can plan an investigation to explore solubility of substances

I can analyze data to compare how different substances dissolve

I can explain how substances are classified by their properties

I can memorize the periodic table

2. What does it mean for a substance to be "soluble"?

It can change color when heated

It can dissolve completely in another substance

It floats on top of water

It becomes solid when cooled

3. Based on your experience, predict what will happen when you add salt to water versus oil:

Salt in water: ________________________

Salt in oil: ________________________

🔬 Part 2: Investigation Planning

4. Your group will test the solubility of these substances. Check which pair your group is assigned:

Butter in water & oil

Baking soda in water & oil

Road salt in water & oil

Fat & soap in water & oil (extension)

5. Write your hypothesis. What do you predict will happen and why?

6. Identify the variables in your investigation:

Independent variable (what you will change): ________________________

Dependent variable (what you will observe): ________________________

Constants (what will stay the same): ________________________

7. List the steps of your investigation procedure:

Step 1: ________________________________________________

Step 2: ________________________________________________

Step 3: ________________________________________________

Step 4: ________________________________________________

Step 5: ________________________________________________

📊 Part 3: Data Collection & Analysis Planning

8. How will you know if your substance is soluble? Describe what you will observe:

9. Create a simple data table to record your observations:

10. What safety considerations should your group follow during this investigation?

11. Extension Challenge: How could you test the effect of temperature on solubility?
