3. Read the passage and complete the flow chart.

Most plants can make their own food showing an autotrophic mode ofnutrition. Some plants also show a heterotrophic mode of nutrition.Heterotrophic plants can be further classified as parasitic, saprophytic,insectivorous and symbiotic plants. This classification depends on how theseplants obtain their food.

4. Convert the scales of temperature (Celsius and Fahrenheit) using thegiven formula.

A. Convert 20°C into °F.

B. Convert 68°F into °C.

5. Read the passage and answer the questions that follow.

Anita’s mother was heating water in a metal (a conductor) container with aplastic (an insulator) handle. Anita accidently touched the pan and found itvery hot. “Use the handle to pick up the pan,” instructed her mother.

A. What 1 difference in the features of insulators and conductors can you inferfrom this passage?

Vikas read that substances can be classified as acids and bases. Acids are sourand soluble in water, while bases are bitter and slippery to touch.Vikas collected 6 samples to see if they contained acids or bases – lemon juice,soap, tamarind, curd, detergent, and milk of magnesia.Sort this list of acids and bases in the correct columns.

Global Winds: The unequal heating of land and water causes wind currents. This createsa difference in air pressure across different regions. Regions closer to the equator receivethe direct rays of the sun, whereas regions near 30°N and 30°S latitudes receive itsslanting rays. Cold winds that blow from these latitudes towards the equator are calledTradewinds. Hot winds that rise from these latitudes and blow towards 60°N and 60°Slatitudes are known as the Westerlies.Air at 60°N and 60°S latitudes is relatively warmer than the air at the north and southPoles. Cold winds from two Poles blow towards 60°N and 60°S latitudes, and are knownas the Polar Easterlies. The motion of global winds is clockwise in the SouthernHemisphere, and anti-clockwise in the Northern Hemisphere.

Pages 3 to 10



A. Name 3 types of global winds along with their latitude bands.B. Draw a labelled diagram to show global winds as per their latitude bands.

Also, show the direction of their movement using arrows.

C. Which 2 types of global winds prevail in India?D. How can knowing about global winds be helpful in predicting severe

weather conditions like cyclones?


A. How are the climatic conditions of the Polar Regions different from theclimatic conditions of deserts?

B. Explain how the features of a polar bear help it to survive in the PolarRegions.

C. Explain how the features of a camel help it to survive in the desert.

D. Is it possible for a polar bear to adapt to the climatic conditions of a desertif it is left there? Give a reason for your answer.

Adaptation in Animals: The deserts and Polar Regions have the mostextreme climates on Earth. The special features of animals living in theseplaces help them to adapt and survive the extreme environment. Over time,the animals of these regions have evolved and now have special features tosurvive the climatic conditions of the regions they live in. For example, polarbears living in the Polar Regions have two thick layers of fur, long curvedand sharp claws, and a strong sense of smell. On the other hand, camelsthat live in the desert have two rows of long eyelashes, long legs andpadded feet, and a coat of hair on the back.

13. Read the passage, look at the pictures and answer the questions.

Different types of soil differ in their capacity to absorb water and the rate ofpercolation (the downward movement of water).The water absorption capacity of soil can be measured as:

The percolation rate of soil can be calculated as:

The pictures show experimental set-ups to compare the properties of twotypes of soil. In the given set-ups, 100 ml of water is poured over two 250 gsamples of soil.

A. Which type of soil has a higher water absorption capacity?B. What does the higher amount of water absorbed show about the capacity

of a soil type to hold water?C. Calculate the percolation rate of sandy soil if it absorbs the poured water in

20 minutes.

D. How does knowing the water absorption capacity and percolation rate of asoil type help a farmer?

E. How else can knowing the water absorption capacity and percolation rateof a soil type be helpful? Write any 1 way.

14. Read the passage, look at the picture, and answer the questions thatfollow.

Blood helps in carrying oxygen from the lungs to cells of the body, andcarbon dioxide from the cells of the body to the lungs. The heart and bloodvessels (veins, arteries and capillaries) help in the circulation of oxygenated(more oxygen and less carbon dioxide) and deoxygenated (less oxygen andmore carbon dioxide) blood in the body as shown in the picture.

A. Write 1 difference between veins and arteries.B. What is the role of the capillaries in the circulation of blood?C. Explain the circulation of oxygenated and deoxygenated blood from the

lungs to cells.
