|1. Given below are a few chemical processes:
a. Rusting of iron
b. Burning of candle
Which two of these represent slow combustion?
|2. The smallest of living organisms with cell wall are
|3. When CNG or LPG undergoes complete combustion, the products formed are
(1) CO2 and H2O
(2) CO2 SO2 and H2O
(3) CO2 only
(4) CO2, CO and H2O
|4. Assessment in Science should focus more on testing the ability of students to
(1) answer open-ended questions
(2) be sufficiently equipped for higher learning
(3) state the facts and principles of Science correctly
(4) apply the understanding of concepts to unfamiliar situations in everyday life
|5. The SI unit of calorific value is
|6. The process of converting sugars into alchohols is known as
|7. One of the main limitations of the Project method of teaching Science is that
(1) knowledge is not acquired in a sequential manner
(2) integration of concepts in various subjects can be achieved
(3) the students have to perform excessive mental and physical work
(4) it is a psychological method
|8. Summative Assessment in Science should mainly focus on
(1) assessing observation skills
(2) diagnosing the areas of learning difficulties of students
(3) tesing of mainly the practical skills
(4) testing important theoretical concepts Summative assessments are provided at end of a unit to determine how much students have learned.
Summative assessments provide information for determining grades and giving students feedback on
their performance. Such assessments are useful for making final judgments about student achievement
and instructional effectiveness.
|9. The dietary fibres are
(1) made up of collagen fibres
(2) made up of protiens
(3) also called roughage
(4) made up of cellulose and protiens
|10. If the frequency of vibrations of a body is decreased and its amplitude is increased then
(1) pitch increases but loudness decreases
(2) pitch decreases but loudness increases
(3) both pitch and loudness of sound produced will decrease
(4) both pitch and loudness of sound produced will increase Sound is a wave and waves have amplitude, or height. Amplitude is a measure of energy. The more
energy a wave has, the higher its amplitude. As amplitude increases, intensity or (loudness of sound)
also increases. For most practical purposes the pitch is just the frequency of sound. Pitch is measured
in frequency of sound vibrations per second. If the frequency (i.e rate of vibration) is decreased, the
pitch also decreases.
|11.Which one of the following man-made fibres is also called artificial silk?
|12. Constructivist approach in teaching science refers to
(1) providing more and more reading materials to students
(2) providing addtional academic help to weak students
(3) applying different mathematical formulae in solving problems
(4) providing experiential learning to students
|13. The gas which forms carboxy-haemoglobin in the blood, causing suffocation is
(1) Cabon monoxide
(3) Carbon dioxide
|14.Which of the following statements related to earthquakes is NOT correct?
(1) The record of the seismic waves is called seismograph.
(2) The seismograph records the seismogram.
(3) The Ritchter Scale is not linear but logarithmic.
(4) The seismic waves originate from focus.
|15. Which one of the following is the key feature of Formative Assessment in Science?
(1) It is aimed at developing scientific temper in the students.
(2) It is aimed at enhancing practical skills.
(3) It is conducted at the end of the year
(4) It is diagnostic in nature
Formative assessments occur throughout the learning process. An important element of formative
assessment is feedback. Feedback makes the biggest impact when it occurs during the learning process.
|16. Project method in teaching of Science is suited most to
(1) strengthen reasoning skill of students
(2) promote scientific method of working
(3) promote understanding of basic concepts in Science
(4) enhance numerical abilities of students
|17. The following observations were made by students A, B, C and D when they rubbed solid
baking soda on dry litmus paper :
|18. Practical work in Science may be given due to emphasis in order to
(1) to keep proper check on punctuality and regularity of students
(2) help the students verify the theoretical concepts
(3) improve the percentage of marks obtained by the students
(4) help the students develop the habit of maintaining written records
|19. Which one of the following is the major objective of teaching of Science at upper primary stage?
(1) To learn important facts and formulae
(2) To develop proficiency in the solving excercise given at the end of the chapter
(3) To promote rational thinking
(4) To remember names of scientists and scientific discoveries
|20. Antibiotics are effective against
(2) Hepatitis A
(3) Dengue Fever
|21. PET bottles and jar are commonly used for storing edible items. PET is a very familiar form of
|22. When electric current is passed through a metallic conductor, amount of heat produced in the
conductor depends on its
(1) material and thickness only
(2) material, length and thickness
(3) material and length only
(4) length and thickness only
|23. The minerals that are required in the right amount for proper functioning of muscles are
(1) Iodine and fluroine
(2) Iron and Iodine
(3) Iron and Calcium
(4) Sodium and potassium
|24. The gases present in the atmosphere that cause greenhouse effect are
(1) Methane, water vapour, cabon dioxide
(2) Cabon dioxide, oxygen, nitrogen
(3) Carbon dioxide, sulphur dioxide, methane
(4) Nitrous oxide, oxygen, water vapour
|25. When carbon dioxide is passed through clear lime water solution, it turns milky. The milky
appearance of lime water is due to
(1) presence of soluble calcium carbonate
(2) curdling of milk due to lime in lime water
(3) presence of impurities in lime water
(4) presence of insoluble calcium carbonate
|26. In order to determine the acidic, basic or neutral character of solutions, a student tabulated the
following results after experimentation. Which of the following observations has been tabulated
|27. Which one of the following is most suited to the development of scientific skills in students?
(1) Conducting Science Olympiads
(2) Performing laboratory work
(3) Conducting Science quiz
