Class 5 EVS Chapter 3 Tasting to Digesting Questions and Answers
Q: What did Jhoolan put in Jhumpa’s mouth when they were playing the tasting game?
A: Jhoolan put lemon juice, crushed jaggery, and later some cooked karela (bitter gourd) in Jhumpa’s mouth during their tasting game.
Q: Why did Jhoolan tell Jhumpa to close her nose while tasting something?
A: Jhoolan told Jhumpa to close her nose because it makes it harder to identify food by taste alone when you cannot smell it.
Q: What happens when we chew food many times?
A: When we chew food many times, the taste changes. The food breaks down more, mixes with saliva, and starts to digest in our mouth.
Q: Why was Nitu given a glucose drip at the hospital?
A: Nitu was given a glucose drip because she was very weak from vomiting and loose motions. Her body couldn’t keep any food or water, and the glucose drip gave her strength quickly without eating.
Q: What was special about Martin’s stomach?
A: Martin had a hole in his stomach covered by a loose flap of skin after being shot. This allowed Dr. Beaumont to look inside his stomach and take out digestive juices for experiments.
Q: What did Dr. Beaumont discover about food digestion?
A: Dr. Beaumont discovered that food digests faster in the stomach than outside the body. He also found that the stomach churns food to digest it, and that the digestive juice in our stomach is acidic.
Q: What was wrong with Rashmi’s health?
A: Rashmi was very thin with skinny arms and legs but had a pot belly. She was often sick, felt tired, and couldn’t go to school regularly because she didn’t get enough food to eat.
Q: What kind of food did Kailash prefer to eat?
A: Kailash preferred to eat chips, burgers, pizzas, and soft drinks from the market instead of home-cooked food like dal-rice, vegetables, and roti.
Q: How did Dr. Beaumont conduct his experiment with the digestive juices?
A: Dr. Beaumont took digestive juices from Martin’s stomach using a tube. He put pieces of food (like boiled fish) in a glass with the digestive juices and kept it at body temperature (about 30°C). Then he observed how long it took for the food to digest compared to the same food in Martin’s stomach.
