### Understanding the pH Levels of Common Household Items

In this section, we will explore the pH values of various common substances using the interactive tool: “pH of common objects” from eScience. The goal is to categorize each item based on its pH level.

#### pH Categories and Items
- **Less than 1**
  - (Space for objects to be placed)

- **pH 2 - 3**
  - (Space for objects to be placed)

- **pH 3 - 4**
  - (Space for objects to be placed)

- **pH 5**
  - (Space for objects to be placed)

- **pH 6 - 7 (including 7)**
  - (Space for objects to be placed)

- **pH 7 - 8 (including 8)**
  - (Space for objects to be placed)

- **pH 9 - 10**
  - (Space for objects to be placed)

### Substances to Categorize
Below is a list of substances to be sorted into the appropriate pH category:

1. **Bleach**
2. **Soda**
3. **Orange Juice**
4. **Blood**
5. **Coffee**
6. **Lemon Juice**
7. **Hand Soap**
8. **Drain Cleaner**
9. **Water**
10. **Oven Cleaner**
11. **Milk**
12. **Sea Water**
13. **Battery Acid**
14. **Stomach Acid**

### Sorting Instructions
Using the plus signs adjacent to each pH range, place each substance in its correct pH category. This exercise aids in understanding the acidic or basic nature of everyday items and how they compare to the pH scale.

#### Additional Explanation
This exercise uses an interactive sorting method to help users learn and retain the pH values of various substances. These categories hint at the acidic (low pH) or basic (high pH) nature of each substance. Users can click on the plus signs to indicate which items belong in which pH ranges.

Understanding the pH levels helps in making informed decisions regarding safety, especially in handling strong acids or bases like battery acid or oven cleaner. It also shares insight into the relative acidity of common consumables like lemon juice and coffee, or the neutrality of substances like water.
