Question 5

III Pick examples from the poem for the following poetic devices.

1. Simile
2. Alliteration
3. Metaphor

Accepted Answer

1. Simile: 'Like hive of bees' compares a drop of water to a hive of bees.
2. Alliteration: 'Magic talk' repeats the 't' sound.
3. Metaphor: 'Magic talk' personifies the magnifying glass as if it can talk. — Identifying poetic devices requires understanding literary terms and locating examples in the poem.

Question 6

1. In the line, 'A myriad shells show in a scrap of chalk', the magnifying glass reveals _______________.
2. In the line, 'A forest—flowers and trees' the poet uses the imagery of nature to emphasise _______________.

Accepted Answer

1. The magnifying glass reveals many tiny shells that are invisible to the naked eye.
2. The poet uses the imagery of a forest to emphasise how even a small patch of moss can appear vast and complex when magnified. — The visual imagery helps readers imagine the transformation of small objects into large, detailed scenes through magnification.

Question 7

4. In the final stanza the poet shifts from small, everyday objects being magnified to a celestial body like moon because ______.

Accepted Answer

1. The poet uses exclamation marks to express excitement and wonder at the details revealed by magnification.
2. The poet personifies the magnifying glass as if it can talk to emphasize its magical ability to reveal hidden details.
3. This is because it supports the theme of discovery as the speaker reveals the extraordinary in the ordinary.
4. The shift to the moon shows how magnification can extend beyond tiny objects to vast, distant ones, highlighting the power of lenses. — The answers explain the poet's stylistic choices and thematic development in the poem.

Question 8

What is science, and how does curiosity contribute to scientific inquiry?

Accepted Answer

Science is a systematic way of exploring and understanding the natural world through observation, experimentation, and reasoning. Curiosity is the desire to know why and how things happen, which drives scientific inquiry by prompting questions and wonder about the world. — Science involves systematic methods to understand natural phenomena. Curiosity initiates this process by motivating individuals to ask questions and seek explanations, which leads to observation, hypothesis formation, experimentation, and conclusions.

Question 9

Which of the following is the first step in the scientific method?

Accepted Answer

Observation — Observation is the first step in the scientific method as it involves noticing and describing phenomena carefully, which provides the basis for asking questions and forming hypotheses.

Question 10

Identify the correct sequence of steps in the scientific method from the options below.

Accepted Answer

Observation → Hypothesis → Experiment → Data Collection → Conclusion — The scientific method begins with observation, followed by forming a hypothesis, conducting experiments, collecting data, and finally drawing conclusions.

Question 11

Fill in the blank: A _____ is a testable and falsifiable explanation for an observed phenomenon.

Accepted Answer

hypothesis — A hypothesis is a tentative explanation that can be tested through experiments and observations. It must be falsifiable to be scientifically valid.

Question 12

Why is experimentation considered a critical step in the scientific method?

Accepted Answer

Experimentation is critical because it tests the validity of the hypothesis by manipulating variables under controlled conditions. It provides objective evidence to support or refute the hypothesis. — Experiments allow scientists to isolate variables and observe effects, ensuring that conclusions are based on reliable data rather than assumptions or biases.

Question 13

Which of the following best describes a control experiment?

Accepted Answer

An experiment where only one variable is changed while others are kept constant — A control experiment changes only one independent variable at a time to isolate its effect, ensuring fair testing.

Question 14

Explain the difference between independent and dependent variables in an experiment.

Accepted Answer

The independent variable is the one that is deliberately changed or manipulated in an experiment, while the dependent variable is the one that is measured or observed to see the effect of the change. — Understanding these variables helps design fair experiments. For example, in testing sunlight's effect on plant growth, sunlight is the independent variable, and plant growth is the dependent variable.

Question 15

True or False: Scientific experiments must be repeatable and objective to ensure reliability.

Accepted Answer

True — Repeatability and objectivity are essential for scientific experiments so that results can be verified independently and are free from personal bias.
