🧪 Part 1: Planning Your Investigation

1. What question are we investigating?

How does temperature affect ice melting?

How do different substances affect ice melting rate?

How much ice can we melt in one minute?

2. Write your hypothesis (prediction) about which solution will melt ice fastest:

3. What are the three solutions we will test? (Tick all correct answers)

Tap water (control)

Salt water

Sugar water

Alcohol and water mixture

4. What will you measure to compare melting rates?

We will measure the _____________ it takes for ice cubes to completely melt in each solution.

📊 Part 2: Recording Your Results

5. Complete the data table with your group's results:

6. Which solution melted the ice fastest?

7. Was your hypothesis correct? Explain your answer:

8. Why do you think salt affects the melting rate of ice?

9. Give a real-world example where this scientific knowledge is useful:

Putting salt on roads in winter

Making ice cream

Cooking pasta

Watering plants

10. What could you change to improve this experiment next time?
