Proofread & Edit Class 4 Science Textbook

I'm seeking a professional editor to proofread and edit a Class 4 Science textbook. The book is currently in a Word document.

Key areas of focus include:
- Grammar and punctuation: The text should be free of any grammatical and punctuation errors.
- Clarity and readability: The content should be suitable for a 4th grader, so it needs to be clear and easy to understand.
- Formatting and layout: The layout should be consistent and appropriate for a textbook.

Ideal skills and experience for the job:
- Previous experience editing educational material is highly preferred.
- Excellent command of English grammar and punctuation.
- Ability to assess and improve clarity and readability for a target age group.
- Proficiency in Microsoft Word and experience with formatting documents.
