🔬 Part 1: Making Predictions

1. What do you think will happen when we add warm vinegar to baking soda compared to cold vinegar?

The warm vinegar will react faster

The cold vinegar will react faster

Temperature won't make a difference

2. What do you think will happen when we use strong vinegar compared to diluted vinegar?

Strong vinegar will react faster

Diluted vinegar will react faster

Concentration won't make a difference

3. Write your hypothesis (prediction) for today's experiment:

I think that _________________________ vinegar will react fastest because

📊 Part 2: Recording Your Results

4. Temperature Test Results - Record the time it takes for fizzing to start:

Cold vinegar (with ice): _______ seconds

Room temperature vinegar: _______ seconds

Warm vinegar: _______ seconds

5. Concentration Test Results - Record the time it takes for fizzing to start:

Diluted vinegar: _______ seconds

Strong vinegar: _______ seconds

6. Describe what you observed during the reactions. Which test produced the most bubbles?

7. Based on your results, which factors make chemical reactions happen faster? (Check all that apply)

Higher temperature

Lower temperature

Stronger concentration

Weaker concentration

8. Explain why you think temperature affects reaction rate using what you learned today:

9. Give one real-world example where people might want to speed up or slow down a chemical reaction:
