Questions and Solutions
Question 1
Question 2
Question 3
Question 4
Bowl 1: Filled with water.
- Air: The seeds are submerged in water, so they get very little or no air.
- Water: The seeds are completely surrounded by water.
- Changes: The seeds might swell up due to absorbing water, but they are unlikely to sprout properly because of the lack of air.
- Sprouted?: No, or very poorly.
Bowl 2: Chanas kept on a damp cloth/cotton wool.
- Air: The seeds are exposed to air.
- Water: The damp cloth/cotton wool provides sufficient moisture.
- Changes: The seeds absorb water and, with access to air, begin to germinate. You will see small roots emerging from the seeds.
- Sprouted?: Yes.
Bowl 3: Chanas kept dry in a bowl.
- Air: The seeds are exposed to air.
- Water: The seeds receive no water.
- Changes: The seeds remain dry and hard, showing no signs of germination.
- Sprouted?: No.
This activity demonstrates that seeds need both water and air to sprout effectively. Bowl 1 lacks sufficient air, and Bowl 3 lacks water, while Bowl 2 provides both essential elements.
Common mistakes
- Not understanding the dual purpose of soaking (softening and aiding sprouts).
- Forgetting to maintain moisture in the sprouting process.
- Not considering the role of air in seed germination.
- Inability to connect nutritional benefits to eating sprouts.
Revision tips
- Review the list of food items that require soaking and the reasons why.
- Re-read the steps and conditions for sprouting seeds.
- Focus on the 'Do This and Find Out' activity to recall the germination process.
- Understand the importance of water and air for seeds to sprout.
- Discuss the nutritional value of sprouts with family or friends.
Practice MCQs
Q1. Why are food items like beans and pulses soaked before cooking?
Explanation: Soaking softens the hard texture of pulses and legumes, making them easier to cook and also facilitating the process of sprouting.
Q2. Which of the following is a key benefit of eating sprouts?
Explanation: Sprouts are rich in vitamins and minerals, offering significant nutritional benefits to the diet.
Q3. In the seed germination activity, what is the role of the damp cloth or cotton wool?
Explanation: The damp cloth or cotton wool is used to maintain a moist environment, which is essential for the seeds to absorb water and begin germinating.
Q4. What essential element is missing for seeds in Bowl 3 of the activity?
Explanation: Bowl 3 contains seeds without any water, preventing them from sprouting. While they get air, the lack of water is the critical factor.
Q5. How much time does it typically take for seeds to sprout?
Explanation: The activity suggests observing changes after two days, indicating that sprouting typically begins within this timeframe under suitable conditions.
Frequently asked questions
What is the main topic of CBSE Class 5 EVS Chapter 5?
Chapter 5, 'Seeds and Seeds,' focuses on the preparation of seeds for cooking, the process and benefits of sprouting, and the essential conditions for seed germination.
Why do we soak pulses and legumes before cooking?
Soaking softens the hard texture of pulses and legumes, making them easier to cook and also helps in the formation of sprouts.
What are the benefits of eating sprouts?
Sprouts are highly nutritious and contain essential vitamins and minerals, making them a healthy addition to the diet.
What are the basic requirements for seeds to sprout?
Seeds require water and air to sprout. Moisture is crucial for the seed to absorb water and begin the germination process.
How can students understand seed germination better?
By performing the 'Do This and Find Out' activity in the chapter, students can directly observe and compare how seeds change under different conditions (with/without water, with/without air).
