Practice questions

Q1A teacher presents this situation: 'Two identical iron nails are kept for a week, one in dry air and one partly dipped in salt water. Why does one rust faster?' Students list possible causes, choose what evidence is needed, plan a comparison, and revise their answer after results. Which method is most precisely represented?

A Lecture cum demonstration method, because the teacher uses a visible example before explaining rusting.

B Textbook method, because the example is common enough to be answered by reading the chapter on metals.

C Problem solving method, because learners move from a problematic situation to hypothesis, evidence collection, testing and revision of explanation.

D Deductive method, because the teacher should first give the law of corrosion and then ask students to apply it to the nails.

Explanation

The problem solving method begins with a felt difficulty or puzzling situation and proceeds through analysis, hypothesis formation, collection or use of relevant evidence, and testing or revision. The nail-rusting task is not merely an illustration of a known law; it requires learners to identify variables such as moisture and salts, design a comparison, and defend a conclusion. That makes the method more exact than simply calling it a demonstration.

Q2The best description of a school science club is that it is

A a student-centred forum for activities such as exhibitions, projects, quizzes, lectures and field visits

B a punishment group for students who do not submit practical files

C a substitute for all regular science periods in the timetable

D a teacher-only committee for buying laboratory materials

Explanation

A science club widens the learning environment beyond the classroom and laboratory period. Through projects, displays, science talks, fairs and visits, it encourages curiosity, leadership, teamwork and application of science in daily life.

Q3A teacher writes the objective: 'Students will compare two methods of water purification and decide which is more suitable for a village during floods, giving reasons.' Which Bloom level is mainly targeted?

A Evaluation, because students compare alternatives and justify a decision using criteria

B Knowledge, because students remember names of purification methods

C Comprehension, because students translate the textbook paragraph in their own words

D Application, because students only use a formula in a familiar numerical problem

Explanation

The objective asks students to compare alternatives, select the more suitable method and give reasons. In Bloom's original cognitive taxonomy, such reasoned judgement against criteria belongs mainly to evaluation. It is more demanding than recall, comprehension or routine application because the learner must defend a choice.

Q4A learner says, "I will accept the result only after checking the data, even if it contradicts my first idea." Which component of scientific attitude is most clearly shown?

A Respect for evidence and willingness to revise judgement

B Preference for quick conclusions

C Mechanical obedience to a laboratory manual

D Dependence on authority

Explanation

Scientific attitude includes habits such as objectivity, open-mindedness, intellectual honesty, respect for evidence and suspended judgement. In the given statement, the learner does not cling to an initial idea; the learner is ready to revise judgement after examining data. That makes respect for evidence and willingness to reconsider the best description.

Q5During a lesson on sound, a science teacher coordinates with the music teacher so that students relate frequency, pitch and musical notes in the same week. Which type of correlation is being used?

A Correlation with daily life only

B Correlation within different branches of science

C No correlation, because music is outside the science syllabus

D Correlation of science with another school subject

Explanation

In pedagogy of science, correlation may be made with daily life, within different branches of science, or with other school subjects. The sound-and-music example is not merely an everyday illustration; it is a planned curricular link between physics content and the school subject of music. Such correlation helps students see that knowledge is interrelated rather than confined to separate compartments.

6While preparing a unit test in science, a teacher lists learning outcomes vertically and cognitive levels such as knowledge, understanding, application and reasoning horizontally, then distributes marks across the cells. What is this document primarily called?

ABlueprint or table of specifications

BProgress card

CAnswer key

DAnecdotal record

7Which objective is most appropriate for science teaching at the secondary stage according to an inquiry-oriented curriculum view?

ARestricting learning outcomes to definitions and labelled diagrams for examination recall

BEngaging students in science as a composite discipline through experiments, tools, local projects and analysis of environment and health issues

CAvoiding practical work so that the syllabus can be completed only through lectures

DTeaching science as unrelated fragments of physics, chemistry and biology from the beginning

8In organising a secondary science curriculum, the principle of continuity is best represented by which arrangement?

AMoving from observable cell structures to chromosomes, inheritance patterns and then applications of genetics

BTeaching all physics topics in alphabetical order to make the index easy to follow

CRepeating the same definitions in every class without adding new depth or application

DPlacing advanced genetics before students have studied cells, chromosomes and heredity

9Which sequence best represents a sound use of the scientific method in a school investigation?

AConclusion, belief, observation, rejection of data

BObservation, identification of pattern, hypothesis, prediction or model, testing and conclusion

CGuess, announcement, copying by peers, acceptance

DTextbook reading, memorisation, recitation, marks

10A teacher uses the following sequence to develop the concept of acids: students test lemon juice, vinegar, tamarind water and dilute hydrochloric acid with blue litmus; they note the common colour change; then the teacher formulates the generalisation. Which pair correctly identifies the approach and the strongest reason?

ADeductive approach, because a scientific definition must always be taught before examples are shown.

BProject method, because learners use real household materials such as lemon juice and vinegar.

CInductive approach, because learners compare particular cases and then arrive at a general rule about acids and litmus.

DProblem solving method, because students handle a difficulty and must remove it by applying a known principle.

11Which activity is most suitable for developing healthy competition and quick recall of scientific concepts among students?

ACancelling all group activities before examinations

BScience quiz

CSilent copying of the textbook index

DLocking the laboratory after every theory class

12In planning a laboratory lesson on factors affecting the rate of evaporation, which teacher decision most strongly protects the pedagogic value of the laboratory method?

ALetting every group change several variables at once so that they can finish more trials and feel more autonomous.

BKeeping only one variable different across comparable setups and requiring learners to record actual observations before drawing the generalisation.

CPreparing a long theoretical lecture first so that every learner can reproduce the definition of evaporation before entering the laboratory.

DReplacing the practical work with a video of the experiment because the video can show more attractive close-up shots.

13A lesson objective states: 'Students will classify the given reactions as combination, decomposition, displacement or double displacement after observing the equations.' In Bloom's original cognitive taxonomy, this objective is best placed at which level?

AKnowledge, because students only recall the names of reaction types

BSynthesis, because students create a new theory of chemical reactions

CApplication, because students use learned categories to classify new examples

DEvaluation, because students assign marks to the equations

14Which practice best reflects safe and effective management of a school science laboratory?

AUsing the laboratory only for annual inspection days

BKeeping apparatus labelled, maintaining stock records and giving safety instructions before practical work

CPermitting students to perform any experiment without teacher supervision

DIssuing chemicals without labels so that students learn by guessing

15Which statement correctly distinguishes a science quiz from a science fair?

AA science quiz mainly uses question-answer rounds, while a science fair mainly involves display and explanation of projects or exhibits

BA science quiz requires apparatus, but a science fair forbids models

CA science fair is only a written examination with marks

DA science quiz and science fair are identical in method and assessment
