Based on the questions from "The Magic School Bus - For Lunch," here are the correct answers and explanations for each:
---
1. What is the first step in digestion?
✔ C. chewing
*Explanation:* Digestion begins in the mouth, where food is broken down physically by chewing (mastication) and chemically by saliva. This is the very first step before food travels to the stomach.
---
2. The esophagus connects the ______ and the ______.
✔ B. mouth and stomach
*Explanation:* The esophagus is a muscular tube that carries swallowed food and liquids from the throat (pharynx, which is connected to the mouth) down to the stomach.

3. What is the blue thing in Arnold’s stomach?
✔ B. a blueberry
*Explanation:* In the episode “For Lunch,” Ms. Frizzle shrinks the class and the bus to travel through Arnold’s digestive system. They find a blueberry in his stomach — it’s literally a piece of food he ate.
---
4. What was eating the bus in the stomach?
✔ C. stomach acid
*Explanation:* In the story, the bus gets coated with stomach acid, which starts to corrode it. Stomach acid (hydrochloric acid) helps break down food — and in this case, it nearly “ate” the bus!
---
5. Where did they go after the stomach?
✔ A. The small intestine
*Explanation:* After the stomach, digested food moves into the small intestine, where most nutrient absorption occurs. The Magic School Bus follows this path through Arnold’s body.
---
6. What is the large intestine like?
✔ B. very stinky and dry
*Explanation:* The large intestine absorbs water from indigestible food matter and forms feces. It’s described as “stinky and dry” because it contains waste products and bacteria, and much of the water has already been removed.
---
7. Why did they back up?
✔ C. They didn’t want to end up in the toilet
*Explanation:* At one point, the bus is heading toward the rectum and anus — the final exit. To avoid being flushed away (and ending up in the toilet), they reverse direction and escape through vomiting.
---
8. What did Arnold do to help the bus leave his body?
✔ A. He got sick and threw up.
*Explanation:* Arnold becomes nauseous (likely from the bus moving around inside him), and he vomits — which allows the Magic School Bus to be expelled from his body safely, avoiding the toilet route.
