Part 1: Before You Begin

1. What do you predict will happen to the ginger bug as it develops?

2. Which signs might show that fermentation is occurring? Select all that apply.

Bubbles appear

The mixture becomes fizzy

The smell changes

The mixture freezes

3. Why is it important to observe and measure the ginger bug regularly?

Part 2: Daily Ginger Bug Observations

Record your observations each time you examine the ginger bug. Use descriptive words such as cloudy, clear, fizzy, sweet, sour, strong-smelling or bubbly.

4. Day 1: Describe the colour, smell, appearance and amount of bubbling.

5. Day 2 or 3: What changes can you observe?

6. Day 4 or 5: What evidence suggests that fermentation is taking place?

7. Choose one day when the ginger bug changed noticeably. Describe the change and suggest what may have caused it.

Part 3: pH Testing and Conclusions

Use pH paper or a pH meter as instructed. Record the pH value and compare it with your observations. A lower pH means the mixture is more acidic.

8. Record your pH results.

Day tested: ____________ pH: ____________

9. Did the pH increase, decrease or stay about the same? What does this suggest about the ginger bug?

10. Write a conclusion about how the ginger bug changed over time. Include evidence from your observations and pH tests.
