I. The coronavirus has transformed life as we know it. Even though school buildings are shuttered,

learning has not stopped. Writing can help us reflect on what’s happening in our lives and form new

ideas. We want to help inspire your writing about the coronavirus while you learn from home.

Students! Here we offer you a project based on the situation that we are living at present.

Create a Journal or a Case Study highlighting your thoughts and your emotions, especially in

anxiety-ridden times.

Here are a few writing prompts to get you started:

• How has the virus disrupted your daily life?

• What changes, big or small, are you noticing in the world around you?

• What are you missing- School, sports, competitions, co-curricular activities, social plans,

vacations, or anything else?

• What effect did this crisis have on your mental and emotional health?

• How is your family dividing responsibilities during the quarantine?

• Are you Face Timing with grandparents, zooming with cousins or doing virtual family check-

ins more often than usual?

• What is your opinion of the leadership, masks and what are your Post-Quarantine Plans?

Material to be used: -

• A 4 sheets

• Highlight each prompt neatly on separate sheets and compile it in a file.

• Pictures, drawings, or sketches based on your thoughts and opinions regarding the situation.

II Write a paragraph in about 100-150 words on the following topics:

• Biased Media is a Real Threat to Democracy

• Language is the Road Map of a Culture

• Pen is Mightier than the Sword

way when suddenly two teenagers on bike overtook his car…..

• The moment Hari stepped down from the train he was greeted at the platform by the people of

his small town. They had gathered there with garlands and a band…..

SCIENCE

PHYSICS

ACTIVITY PLAN FOR THE CHAPTER : MOTION

To understand that the distance and displacement concept (i.e. displacement of an object is

always equal or smaller than distance, it can never be greater than distance).

★ Go from one corner of your living room to the opposite corner by different routes

possible . Measure the distance travelled with a measuring tape and note the

observations.

★ Now measure the length of the diagonal of the living room and note the

observations. You can try the same in other rooms also.

★ Record all the observations and represent them in tabulated form.

Answer the following questions:

1. Derive all three equations of motion by graphical method

2. A ball thrown vertically upwards with a speed of 19.6 ms-1 from the top of a tower returns

to the earth in 6 seconds. Find the height of the tower (take acceleration = 9.8 ms-2)

3. Two balls of different masses are thrown vertically upward with the same initial velocity.

Maximum heights attained by them are h1 and h2 respectively. What is h1/h2?

4. A ball is thrown upward with a speed of 49 ms-1 and at the same time another ball is

dropped from the top of a tower of height 100 m. Then after how much time they will meet each

other and what is the position of the stones?

5. A 8000 kg engine pulls a train of 5 wagons, each of 2000 kg, along a horizontal track. If the

engine exerts a force of 40000 N and the track offers a friction force of 5000 N, then calculate:

(a) the net accelerating force and

(b) the acceleration of the train.

6. A hockey ball of mass 200 g travelling at 10 m s–1 is struck by a hockey stick so as to return it

along its original path with a velocity at 5 m s–1. Calculate the magnitude of change of

momentum occurring in the motion of the hockey ball by the force applied by the hockey stick.

7. A bullet of mass 10 g travelling horizontally with a velocity of 150 m s–1 strikes a stationary

wooden block and comes to rest in 0.03 s. Calculate the distance of penetration of the bullet into

the block. Also calculate the magnitude of the force exerted by the wooden block on the bullet.

8. How much momentum will a dumb-bell of mass 10 kg transfer to the floor if it falls from a

height of 80 cm? Take its downward acceleration to be 10 m s–2 .

TASK 1

“By failing to prepare, you are preparing to fail”.

―Benjamin Franklin

India's coasts are extremely vulnerable to cyclones. With a coastline of 7517 km, the country

is exposed to nearly 10 percent of the world's most devastating tropical cyclones.

Although cyclones affect the entire coastal regions of India, the eastern coast of India

specifically has witnessed some of the most damaging cyclones in the last century. This year too,

the coast of West Bengal and Odisha was hit by an annihilating cyclone.

Prepare a Research Project/PowerPoint Presentation on the Case Study of West Bengal and

Odisha’s Cyclones and include the following points in your project:

● The name of the cyclone, which affected West Bengal and Odisha in May 2020 and

how it got its name

● The name of the cyclone which hit Odisha’s coastal region in 2018 and 2019 and how

that too, had got its name.

● The reasons that made the 2020 cyclone get classified as the ‘worst cyclone’ to have

hit coastal West Bengal and Odisha.

● A comparative analysis of both the cyclones with respect to their intensity, area, and the

damages caused.

● The measures taken by the government to minimize the loss caused by the 2020 cyclone

and its evaluation.

● Valuable lessons learnt by the people of West Bengal and Odisha towards preparedness

for natural disasters.

NOTE: The project should be neat, well presented, researched and pictorial. Cover page,

table of contents, acknowledgements, bibliography, headings and sub – headings are a must.

· The project should not exceed 15 pages/15 slides

· Do not exceed 700 words

· The project carries 5 marks: Content accuracy and originality – 2 marks

Presentation and creativity – 2 marks

Viva voce - 1 mark

TASK 2

Technology today is taking a big leap towards Artificial Intelligence (AI) and Machine
