SECTION A
(Reading-15 Marks)
Q.1. Read the passage given below and answer the questions that follow by writing the options that you consider the most appropriate in your answer sheet.                                                             (5 Marks)

Imagine 100 people walking on a beach in the middle of the night, stopping every once in a while to search for turtle eggs and hatchlings! I was a part of this walk recently in the heart of Chennai in Tamil Nadu! Our aim was to take them to the safety of a ‘hatchery’.

As we trudged along the beach, we came across the tractor-like tracts of a turtle that must have come ashore to lay her eggs. The tracks are unmistakable. These are caused by the feet and back flippers of the turtle as it drags itself across the sand. But try as we might, we could not locate the nest that the turtle must have dug to drop its eggs. An hour later, we came across another set of tracts, and this time located the nest.

As our expert guides dug, a wave of excitement went through the group…one by one, turtle hatchlings emerged from the hole. They began walking and we guided them to the sea so they could swim off. We found and released 87!

This night exercise has been a part of the unique “turtle walk” organized by conservationists in Chennai for the last 20 years! Every year when the nesting season of the Olive Ridley turtles comes around, people gather to patrol the beach every night. They ensure that no one digs up the eggs or hatchlings to eat them, and when they find eggs, they transfer them to a safe enclosed hatchery.
Why do they need to do this? Because the Chennai beach is visited by thousands of people, and by dogs, and the turtles could easily be disturbed or dug up.

Another threat faced by the hatchling is the lighting across the beach. When they emerge from the nest, these turtles look for the brightest part of the horizon and head there. In natural conditions, this would be the sea. In Chennai, however, it is now brighter inland than at the sea! Chennai’s turtle volunteers spend hours every night to ensure that this does not happen.

1. The Olive Ridley turtles come ashore
(a) to lay eggs in nests
(b) to enjoy the sand on the shore
(c) to save themselves from bigger sea animals
(d) to take rest


2. The author and others were looking for turtle eggs to

(a) being dug up and eaten by people and dogs
(b) being destroyed by children
(c) being disturbed by bright light
(d) being crushed by walkers on the beach

4. The hatchlings do not head towards the sea on their own because
(a)  they are too young to know the direction
(b)  they are attracted towards the bright lights inland
(c)  they are afraid of going to the sea
(d)  the sea waves are very strong



5. the word in the passage which means the same as “people engaged in protection of    
    valued  resources” is

Q.2. Read the following passage and write the options that you consider the most appropriate in your answer sheet.                                                                                                              (5 Marks)

Ever wondered about those tall structures that are landmarks along every shore all over the world?  Lighthouses.  We see them in pictures and in movies and along every seashore.  Tall, stately structures looking out to sea, warning the incoming ships of approaching land.

Did you know what served as a lighthouse in the early years?  The locals from the area would light a fire at a height to warn boats of any impending dangers like rocks or even land.  The early constructors of lighthouse included the Greeks, Romans and Phoenicians.

How do you think these lighthouses showed the way to incoming ships?  Those were the days when technology had not taken over the world.  The lighthouses used lamps to guide the ships.  However, these lamps could throw light only as far as a few miles into the sea.  It was only much later that mirrors, prisms, electricity and the automatic working of a lighthouse came to be.  It is indeed amazing what these stately structures out in lonely locations across the world mean to the sailors as they near land after days out at sea.
Did you know that the Lighthouse of Alexandria is one of the Seven Wonders of the Ancient World?  It was located on the island of Pharos in Egypt and it was built in 290 BC.  The lighthouse used fire at night and reflected the sunrays during the day to warn sailors of land.  This monument is a legacy in the world today although it was destroyed by several earthquakes that hit it in the 1300s.
Today, in its place stands a fort built in 1480 using the marble and stones from the lighthouse, a breathtaking structure that came down ravaged by nature.

  1. Lighthouses are built
(a)   to show direction to the ships
(b)   to warn the ships of approaching land or rocks
(c)   to show technological development
(d)   to keep a check on the ships at the sea


  1. Lighthouses used only fire in the early years because
(a)   electricity was yet to be discovered
(b)   technology was not used
(c)   automatic lighthouses had stopped working
(d)   sailors wanted only fire to be used

  1. The fort built in 1480 is unique because
(a)   it is a legacy in the world today
(b)   it was destroyed by several earthquakes
(c)   it is a breathtaking structure savaged by nature
(d)   it was built with the marble and stones from the destroyed lighthouse

  1. The lighthouse of Alexandria
(a)   is located on the island of Pharos in Egypt
(b)   was destroyed in the 1300’s
(c)   helps sailors today
(d)   used electricity at night

  1. An important building/ structure that is easy to recognize is called a
(a)   stately structure
(b)   tall structure
(c)   beacon
(d)   landmark

And folk began to stare
“We cannot eat it, that is flat!

Class 10 Chapter 02 Acid Bases and Salts NCERT Activity Explanation

NCERT Activity Chapter 02 Acid Bases and Salt Class 10 Chemistry Activity 2.1 Indicator Acid Base Red litmus No Change Blue Blue Litmus Red No change Phenolphthalein Colourless Pink Methyl Orange Pink   Yellow Indictors are substance which change colour in acidic or basic media. Activity 2.2 There are some substances whose odour changes in in acidic or basic media. These are called olfactory indicators. Like onion vanilla, onion and clove. These changes smell in basic solution. Activity 2.3 Take about 5 mL of dilute sulphuric acid in a test tube and add few pieces of zinc granules to it. => You will observe bubbles of hydrogen gas on the surface of zinc granules. Zn + H2SO4 --> ZnSO4 + H2 => Pass the Hydrogen gas through the soap solution. Bubbles formed in the soap solution as Hydrogen gas it does not get dissolved in it

Class 10 Metal and Non MetalsChapter 03 NCERT Activity Solutions

X Class 10 NCERT Activity Explanation Class 10 Metals and Non Metals Activity 3.1 Page No. 37 Take samples of iron, copper, aluminium and magnesium. Note the appearance of each sample. They have a shining surface. Clean the surface of each sample by rubbing them with sand paper and note their appearance again. They become more shiny. => Freshly cut Metal have shiny surface Activity 3.2 Page No. 37 Take small pieces of iron, copper, aluminium, and magnesium. Try to cut these metals with a sharp knife and note your observations. They are very hard to cut. Hold a piece of sodium metal with a pair of tongs and try to cut it with a knife. Sodium can be cut easily with knife. Hence K and Na are soft metal cut with knife Activity 3.3 Page No. 38 Take pieces of iron, zinc, lead and copper try to strike it four or five times with a hammer. These metals are beaten into thin sheet on hammering. This property of metal is called malleability and metals are called malleable. Activity 3.4 Page

CBSE I NCERT 10th Numerical Problem solved Reflection and reflection of light

Q. 1. A concave mirror of focal length 20cm is placed 50 cm from a wall. How far from the wall an object be placed to form its real image on the wall?  Solution: V= -50 cm F= -20cm From mirror formula 1/u = 1/f – 1/v = -1/20+ 1/50 = - 3/100  U = - 33.3 cm Therefore, the distance of the object from the wall x =  50 – u X = 50 – 33.3 = 16.7 cm. Q.2. An object is placed at a distance of 40cm from a concave mirror of focal length 15cm. If the object is displaced through a distance of 20 cm towards the mirror, By how much distance is the image displaced? Answer: Here f = - 15 cm, u = - 40 cm Now 1/f = 1/u + 1/v Then 1/v = 1/f – 1/u Or V= uf/u-f =( - 40 x -15)/25 = -24 cm Then object is displaced towards the mirror let u1 be the distance object from the Mirror in its new position. Then u1 = -(40-20) = -20cm If the image is formed at a distance u1 from the mirror then v1 = u1f/u1-f = -20X-15/-20+15 = -60 cm. = - 20 x-15/-20+15 = -60 cm. Therefor
