Physical Science Reading Passage: Acids and Bases (Fillable PDF)

Physical Science Reading Comprehension Passage and Questions: Acids and Bases (Fillable PDF)

This very engaging science reading passage is about acids and bases and how they appear in everyday materials. It explains that acids release hydrogen ions in water and are found in substances such as lemon juice, vinegar, citrus fruits, and stomach acid. It also describes bases, including soap, baking soda, ammonia, and cleaners, and explains how scientists use the pH scale to compare how acidic or basic a substance is. The passage introduces neutralization reactions, showing how acids and bases can react to form water and a salt, and connects the topic to real-life uses in farming, medicine, cooking, and cleaning.

This passage is designed to bridge the gap between science and literacy by strengthening reading comprehension while sparking scientific curiosity in middle school students.
