Improve Your Learning

Question 1.
How are clouds formed ? Explain. (Conceptual Understanding) 8 M
Answer:

1. On a sunny day, the sun heats up the ground as well as the water in seas, oceans, rivers, ponds etc. This water converts into water vapour by the process of evaporation.
2. Evaporation is the process of water changing into water vapour.
3. Evaporation is a natural process which takes place on the earth.
4. Water evaporates continuously from the surfaces of water bodies like seas, oceans, rivers, ponds etc., and changes into water vapour due to the heat supplied by sunlight.
5. The water vapour entered into air through the process of evaporation forms clouds in the sky.

Question 2.
How does the rain water reach from clouds to rivers or oceans?
(Or)
Describe the relationship between oceans and rains. (Conceptual Understanding) 8M
Answer:

1. The water in the water bodies gets heated up and converts into water vapour by the process of evaporation.
2. When water vapour reaches higher levels it condenses due to contact with cool air and forms water droplets.
3. These droplets remain floating in air at higher levels of the atmosphere and appear as clouds.
4. Sometimes the cool breeze coming along with air makes the clouds cooler.
5. This leads to water in the clouds condense and form large water drops.
6. When the size of the water drops increases further it becomes difficult for the cloud to hold them and water drops begin to fall on the earth. This is called rain.
7. In this way the rain water reaches from clouds to rivers and oce.

Question 3.
When do clouds become cool ?
(Or)
Explain the changes that take place in clouds before it rain.
(Or)
How do you imagine that it is likely to rain?
(Or)
Water vapour converts into clouds. How clouds turn into rain?
(Or)
Krishnaveni said, “The raining takes place from clouds”. What are the observations you make at the time of raining ? (Conceptual Understanding) 4 M
Answer:

1. Winds bring the clouds from the sea to the land. Clouds are nothing but evaporated water.
2. The colder air in the upper layers of the atmosphere cools the clouds.
3. The clouds moving in air are generally at higher levels.
4. Sometimes the cool breeze coming along with air makes the clouds cooler.
5. These cool clouds bring rain.

Question 4.
Explain the relationship between the heat of sun and evaporation. (Conceptual Understanding) 4 M
Answer:

1. On a warm day, the sun heats the ground as well as the water in the water bodies.
2. This water converts into water vapour by the process of evaporation.
3. More the sun heats up the water from water bodies, the more evaporation of water occurs.
4. The formation of clouds depends on the amount of water that evaporates due to sun heat.

Question 5.
Why do we experience cloud like smoke near our mouth while we speak during the winter season ? (Asking Questions and Making Hypothesis) 4 M
Answer:

1. In winter, the air in our atmosphere is very cool as compared to the air coming out from our mouth.
2. Water vapour present in the air coming out from our mouth gets cooled suddenly to form very tiny droplets.
3. These tiny droplets concentrated in a limited area, appear like smoke or a small cloud near our mouth.

Question 6.
Correct the given sentence if necessary.
“If the size of water drops decreases in the clouds, they can no longer hold the water drops.” (Asking Questions and Making Hypothesis) 4 M
Answer:

1. The given sentence is not applicable for the characteristic feature of the appearance of the clouds.
2. When water vapour reaches higher levels it condenses due to contact with cool air and forms small drops or water droplets.
3. These tiny droplets remain floating in air at higher levels of the atmosphere and appear as clouds.
4. Therefore if the size of water drops decreases in the clouds, they can hold water drops.

Question 7.
Which of the following days is more suitable for drying of washed clothes? Explain why. a) Windy day b) Cloudy day (Conceptual Understanding) 4 M
Answer:

1. Windy day is more suitable than the cloudy day for drying of washed clothes.
2. The rate of evaporation increases with the wind flow.
3. Cloudy atmosphere has less capacity of evaporating water into vapour than windy atmosphere. The evaporation will be slow.
4. Clothes dry faster in windy atmosphere, and slower in cloudy regions.

Question 8.
Which of the following statements are right (Or) wrong ? (Conceptual Understanding) 4 M
a) Evaporation takes place quickly when more heat is supplied.
b) For condensation of water vapour, it should be cooled.
c) Water vapour is obtained from water by its evaporation.
Answer:
The three given statements are true to their nature.
(a) Evaporation takes place quickly when more heat is supplied.

(b) When water vapour gets cooled, it turns into water. Cool air converts water vapour into water droplets which in turn finally into water by the process of condensation.

(c) The process of changing of water into water vapour is called evaporation.

   For the leisure of creatures and their sake

Question 11.
Clouds once seen at a particular point, may not be there after sometime? Why? (Asking Questions and Making Hypothesis) 4 M
Answer:

1. The clouds once seen at a particular point may not be there after sometime.
2. This is because of the movement of clouds from high pressure areas to lower pressure areas.
3. Pressure influences the movement of clouds.
4. The difference in pressures in two different areas leads to the movement of air.
5. Thus the clouds also move along with air from high pressure area to low pressure area.

Question 12.

Revanth blew air from his mouth onto the mirror. He confused at the appearance of moist layer on the mirror. He doubted and may have questioned himself in the following way.

1. What is the reason for the formation of some moist layer on the mirror ?
2. Why did the mirror become unclear after blowing air on it by mouth ?
3. What comes out of my mouth while blowing ?
4. Does it happen even for other animals also ?

Question 13.
If it is raining in a village you don’t find rain another village. Why do you think it is happening so? (Asking Questions and Making Hypothesis) 8 M
Answer:

1. Often we see that there may be rain in some area, where it may not be in its adjacent areas.
2. This is because of condensation of clouds due cool air which affects on them in the specific area.
3. Occurance of winds won’t be same in all the areas. Pressure influences on the presence of air.
4. Clouds along with winds move from high pressure area to low pressure area at which cool air occurs.
5. That’s why rain is seen only in some areas, where we can’t see it in its adjacent areas.

Question 14.
If condensation fails to occur innature what happens? (Asking Questions and Making Hypothesis) 8 M
Answer:
If there is no occurance of condensation in the water, water cycle stops due to lack of rains. If there are no rains water sources will not be filled with water. Even ground water level decreases. Low percentage of water levels in the natural water bodies cause damage to the living kingdom, thus it finally lead to destruction of nature. Hence condensation process is very essential in the water cycle.

Question 15.
Why does the driver of a vehicle wipe the glass inside, even if the wiper is working on outer surface of the glass when he drives in rain ?
(Aesthetic Sence, Values and Application to Daily Life and Concern to Bio-diversity) 8 M
Answer:

1. The driver wipes the glass inside, even wiper is working on outer surface of the glass when he drives in rain.
2. Because of the natural process called condensation rain that falls on the glass of the cabin cools its surface.
3. Air inside the driver’s cabin contains water vapour which is warmer than the outside surface of the glass.
4. Due to the cold glass, air close to its inner surface will also become cooler.
5. This changes the water vapour in the air of the inner surface of the glass into water and forms small drops on the inner surface.

TS 6th Class Science 1st Lesson Notes – Our Food

• We get food from plants and animals.
• For cooking food, we need different types of ingredients.
• We use different parts of plants like stems, roots, leaves, fruits and flowers as food.
• The taste of food is based on its ingredients, method of preparation and cultural practices of the region.
• Boiling, steaming, fermentation are some methods of preparing food.
• We use preservatives to preserve food for sometime.
• Sugar syrup or honey is a good preservative. Fruits are often preserved in sugar syrup or honey. Jams and fruit juices are good examples of preservation with sugar.
• When you purchase any food item in the market, we should not forget to read about its ingredients and manufacturing date.
• Outdated food material may damage our health.
• Ingredients : The agents which are added in the food.
• Preservatives : The substances which help in storing food.

Stages of safe drinking water supply.

• Water is collected into tank: Untreated water is collected from rivers or lakes into tanks.
• Filtration: The water is filtered through sand particles and grills and then sent to another aerated tank. Nearly 99% of solid wastes are filtered through this process.
• Aeration: Filtered water is exposed to sunlight. As a result some bacteria present in the water bodies will die due to the Sun’s heat.
• Chlorination: Chlorine compounds are used to destroy all the disinfectants present in the water. Now the water is available to be used for drinking.
• Overhead tank: Chlorinated water is pumped into overhead tank before supplying.
• Supply of water: Pure water is supplied to the people through taps.

TS 6th Class Science Important Questions 9th Lesson Plants: Parts and Functions

Question 1.
What is venation ? What is its use?
Answer:
The arrangement of veins in the lamina of leaf is called venation. Venation acts as a skeleton of the leaf and gives it a shape and support.

Question 2.
What is transpiration?
Answer:
Plants release excess water in their body through stomata and some other parts as well. This water is released in the forms of vapour and this process is called transpiration.

Question 3.
What are the functions of root?
Answer:
Roots absorb water and minerals from the soil and also help in anchoring the plant body to the soil.

Question 4.
Name the types of venations we see in the plants.
Answer:
There are two types of venations in different plants.

• Reticulate venation
• Parallel venation

Question 5.
How many types of roots are present in plants and name them.
Answer:
There are two types of root systems.

• Tap root system
• Fibrous root system

Question 6.
What happens when stomata are not present in leaf?
Answer:
If stomata are absent in leaf plants cannot take carbon dioxide which is useful for preparation of food.
Excess of water taken by plants cannot he expelled out. Exchange of gases will be stopped. As a result plant cannot perform its functions.

Question 7.
What would happen if there are no veins in the leaf?
Answer:
If veins are absent the leaves would lose their specific shape and support from the stem. The food that is prepared in the leaf cannot be supplied to the other parts of the plant. The water and minerals coming from the roots (via) stem cannot reach the leaves due to absence of veins.

Question 8.
Prove the experiment. “The excess water is evaporated from plants by the process by transpiration”. With the help of the procedure write the result.
(Or)
Write the procedure you followed for conducting an experiment on transpiration. Write the required material for experiment. What did you observe at last?
