Question numbers to in Section-A are one mark questions. These are to be answered in one word or in one sentence Question numbers 4 to 6 in Sections-A are two marks questions. These are to be answered in about 0 words each Question numbers 7 to 8 in Section-A are three marks questions. These are to be answered in about 0 words each Question numbers 9 to 4 in Section-A are five marks questions. These are to be answered in about 70 words each. Question numbers to in Section-B are multiple choice questions based on practical skills. Each question is a one mark question. You are to select one most appropriate response out of the four provided to you. Page of

2 4 6 Question numbers 4 to 6 in Section-B are questions based on practical skills are two marks questions. SECTION-A State the location of lateral meristematic tissue. What is the numerical ratio of average velocity to average speed of an object when it is moving along a straight path? Name any two common types of wells used for irrigation? How is heating of sugar and heating of ammonium chloride different from each other? Explain your answer. RER SER Give one function each of RER and SER. 6 Distinguish between the terms mass and weight. (Any points) 7 Colloidal solution appears to be homogeneous but actually it is heterogeneous. justification for this statement. Give 8 You are provided a mixture of mustard oil and water. Name the technique to separate it and write the principle involved. Draw diagram of the technique used. Page of

3 9 Mallika s mother was suffering from cold and cough. Mallika prepared tea for her mother. She boiled water in a pan, then she added tea leaves, sugar and milk to it. She filtered the tea in a cup and served to her mother. Explain the values shown by Mallika. Identify solute, solvent, residue and filtrate in this activity. 0 Mitochondria is called power horse of the cell. Justify this statement. Mention the use of deep folding in the inner membrane of mitochondria. (e) (f) Name the following tissues : that form the inner lining of our mouth. that transport food in plants. that store fat in our body. that connect two bones. (e) tissue with a fluid matrix. (f) that are responsible for movement. A ball is allowed to roll down from an inclined plane. It reaches the foot of the plane and continues to roll on the ground. It stops after travelling some distance. Is this the violation of the law of inertia? Give reason for your answer. A player lowers his hand while catching a ball. Explain reason behind this action.

4 Accelerating objects are objects that are changing their velocity. Name the three controls of an automobile that cause it to accelerate km 0 N 6,400 km Find the weight of an object at a height 6400 km above the earth s surface. The weight of the object at the surface of the earth is 0 N and the radius of the earth is 6,400 km. Describe any three effects of force with the help of one example each. 6 Green revolution and white revolution indicate that our natural resources are getting used more intensively. What can be the harmful effects of this? 7 Mention the harmful effects of infectious diseases on the health of cattle. How can you control these diseases? 8? Define Weeds. List two ways by which they affect the crops. How weeds can be controlled? 9 Page 4 of

5 List three characteristics of particles of matter. When we add some sugar or salt in a beaker containing water, after sometime the sugar or salt becomes invisible. Where does it go? What property of particle of matter does it show? How will you justify that ice water and steam are the three states of a substance and not different substances? 0 Name the technique used to separate alum from impure sample. Why is this technique better than simple evaporation technique? Tabulate two differences between physical and a chemical change. Give one example of each. Draw the labelled diagram of longitudinal section of collenchyma and sclerenchyma tissues. Write one function of each. State the universal law of gravitation. Why is it called universal? Derive the formula to calculate the gravitational constant. 4 P Q P Page of

6 (i) (ii) (iii) A ball thrown upwards reaches a point P of its path at the end 4 seconds and the highest point Q at the end of seconds. After how many seconds from the start will it reach the point P again? Draw the distance-time graph for the following situations : (i) (ii) (iii) When a body is stationary When a body is moving with a uniform speed. When a body is moving with non-uniform speed. 4 Define weed. Give two examples. Why is it essential to remove weeds from agricultural fields? What are weedicides? / SECTION - B Which one of the following chemical gives a blue black colour with starch fluorine chlorine iodine bromine 6 Page 6 of

A boy was rushing with a bottle of tincture of iodine. Some iodine solution splashed on his yellow coloured, cotton shirt and also on the white table cloth.

Shirt was starched after washing but the table cloth was not. Table cloth was starched but not the shirt. Shirt has absorbed sweat.

7 A boy was rushing with a bottle of tincture of iodine. Some iodine solution splashed on his yellow coloured, cotton shirt and also on the white table cloth. The stain on the table cloth was yellowish brown while that on his shirt was blue black. The most obvious scientific reason for this is that : - Shirt was dyed with metanil yellow. Shirt was starched after washing but the table cloth was not. Table cloth was starched but not the shirt. Shirt has absorbed sweat. 7 I II III IV Four students were asked to observe the effect of heat on Iron sulphide. The teacher provided them with test tubes, holders and solid Iron sulphide. The students then started heating iron sulphide as shown below. The teacher stopped three of them for using wrong procedures. The correct way of heating is shown in setup : Page 7 of

8 I II III IV 8 9 Raman added carban disulphide in a test tube containing a mixture of iron filings and sulp shaking the test tube he will observe that : A brown gas is evolved. Sulphur dissolves to form colour less solution and iron filings settle down. Sulphur dissolves to form a yellow solution and iron filings settle down. After some time carbon disulphide, sulphur and iron filings form three separa in the test tube. We will observe a precipitation to occur in the solution when : barium chloride is added to sodium chloride Page 8 of

9 barium chloride is added to sodium sulphate sodium sulphate is added to sodium chloride sodium sulphate is added to barium sulphate 0 The stained parts of the onion peel cells are : Cell membrane, nucleolus, cytoplasm Cell membrane, nucleus, vacuoles Cell wall, nucleus, cytoplasm Cell wall, nucleus, vacuoles a b c d Which of the following is characteristic feature of parenchyma tissue? Cells are thin walled and loosely packed Cells have thickenings at corners Page 9 of

10 Cells are thick walled Cells are long narrow without inter cellular space a b c d A mixture can be characterized by : No fixed composition of the components. Homogeneity. No occurrence of chemical reaction. Heterogeneous 0. gwt 69.4 gwt 4. gwt 69 gwt.8 gwt The least count of the spring balance used for measuring minimum force required to move a wooden block on the table is 0. gwt. When the pointer is at 69 th mark, the block starts moving. The force at this point is :.4 gwt 4. gwt 69 gwt.8 gwt 4 A, B, C D Dipti was asked to prepare four separate mixtures in four beakers A, B, C and D by mixing sugar, fine sand, thin paste of starch and chalk powder respectively in water and then categorise each as stable or unstable. What will be correct categorization? (i) (ii) Mention the temperature of the following in degree Celsius and Kelvin Scale :- (i) Ice and ice cold water. (ii) Boiling water and steam. Page 0 of
