QUESTION 1 Question 1.1 [20 marks] Science educators widely agree that
practical work enhances learning in meaningful ways. a) List four main
reasons why practical science is encouraged in the classroom. b) For each
reason, provide a short explanation and describe one classroom situation
where it applies. [4 marks for listing reasons; 4 × 4 = 16 marks for
explanations and examples] 1.1 Explain four reasons why science teachers
include practical activities in their lessons. For each reason, describe one
example of a classroom activity that supports it. (4 reasons x 5 marks each
= 20) 1.2 Discuss five possible reasons why teachers might choose not to
include practical work in science classrooms. Your reasons should reflect
common challenges in real school settings. Question 1.2 [10 marks] Not all
teachers include practical work in their lessons. Identify and explain five
challenges or limitations that prevent teachers from doing so. [5 × 2 marks
= 10 marks] Question 1.3 [10 marks] a) Explain why developing practical
skills is important in everyday life. b) Provide examples of how you would
help learners develop the following skills through classroom science

Question 1.1: Reasons for Encouraging Practical Science in the Classroom
Practical science is widely encouraged in the classroom because it offers unique and meaningful
ways to enhance learning that theoretical instruction alone cannot achieve.
,a) Four main reasons why practical science is encouraged in the classroom:
1. To develop practical and manipulative skills.
2. To enhance conceptual understanding.
3. To foster scientific inquiry skills and critical thinking.
4. To increase motivation and engagement.
b) Explanation and classroom situation for each reason:
1. Reason: To develop practical and manipulative skills.
o Explanation: Practical work provides students with hands-on experience using
scientific equipment, materials, and techniques. This develops their fine motor
skills, precision, accuracy, and safe handling of apparatus, which are essential for
conducting experiments and performing scientific investigations. These skills are
often transferable to everyday life.
o Classroom Situation: In a biology lesson on respiration, students conduct an
experiment to observe the production of carbon dioxide by yeast. They need to
carefully measure yeast, sugar, and water using measuring cylinders and spoons,
set up a fermentation tube with a delivery tube leading into limewater, and
observe the color change. This activity directly develops their skills in measuring,
assembling apparatus, and making careful observations.
2. Reason: To enhance conceptual understanding.
o Explanation: Practical activities allow students to directly observe phenomena,
collect data, and experience scientific principles in action, rather than just reading
about them. This direct interaction helps to consolidate abstract concepts, correct
misconceptions, and build a more robust and memorable understanding of
scientific ideas. It connects theory to reality.
o Classroom Situation: When teaching about circuits in physics, students connect
various components like batteries, wires, bulbs, and switches. By manipulating
these components and observing when the bulb lights up or goes out, they can
directly see the effects of open and closed circuits, series vs. parallel connections,
and the role of a switch. This hands-on experience solidifies their understanding
of electricity flow far more effectively than just drawing circuit diagrams or
reading definitions.
3. Reason: To foster scientific inquiry skills and critical thinking.
o Explanation: Practical work is central to developing the skills of scientific
inquiry, which include observing, hypothesizing, designing experiments,
collecting and analyzing data, interpreting results, and drawing conclusions. It
encourages students to think like scientists, question observations, solve
problems, and evaluate evidence, thereby enhancing their critical thinking
abilities.
o Classroom Situation: Students are tasked with investigating which type of soil
retains the most water. They need to design an experiment, selecting variables to
control (e.g., amount of soil, amount of water, time for drainage) and variables to
measure (amount of water collected). They then collect data, analyze it, and
conclude which soil type is best. This process encourages them to hypothesize,
, plan, conduct, analyze, and communicate, embodying the full cycle of scientific
inquiry.
4. Reason: To increase motivation and engagement.
o Explanation: Many students find practical activities more enjoyable and
engaging than purely theoretical lessons. The hands-on nature, the element of
discovery, and the opportunity to interact with peers can make science lessons
more stimulating and memorable. This increased interest can lead to deeper
learning, better retention, and a more positive attitude towards science.
o Classroom Situation: During a chemistry lesson on acids and bases, instead of
just discussing pH, students use red cabbage indicator (or universal indicator
paper) to test the pH of common household substances like lemon juice, soap,
vinegar, and baking soda solution. The vivid color changes and the act of testing
different substances makes the lesson interactive, exciting, and highly engaging,
making them more curious about chemical properties.
Question 1.2: Challenges Preventing Teachers from Including Practical Work
Despite the numerous benefits, several challenges often prevent teachers from consistently
incorporating practical work into science classrooms, especially in real school settings.
1. Lack of Adequate Resources and Equipment: Many schools, particularly in
underserved areas, suffer from a chronic shortage of appropriate laboratory equipment,
chemicals, glassware, and even basic consumables. Even if equipment exists, it might be
old, broken, or insufficient for an entire class.
o Explanation: Without the necessary tools, it is impossible to conduct many
experiments. Teachers might resort to demonstrations, but this reduces direct
student engagement. The cost of setting up and maintaining a well-equipped
science lab is significant, and many schools simply lack the budget.
o Example: A biology teacher wants students to observe plant cells under a
microscope, but the school only has two old, blurry microscopes for a class of 50
students, making it impractical for all students to have a meaningful hands-on
experience.
2. Time Constraints in the Curriculum: Science curricula are often packed with a vast
amount of content that needs to be covered within a limited timeframe. Practical work is
inherently time-consuming, requiring preparation, setup, execution, cleanup, and often
more time for discussion and analysis than a theoretical lesson.
o Explanation: Teachers feel pressure to "cover the syllabus" and often perceive
practical work as taking too much time away from content delivery, especially
when facing external examinations. This leads them to prioritize lecturing and
textbook work over practical engagement.
o Example: A physics teacher has a unit on waves, and while they know a lab on
sound waves would be beneficial, they only have two class periods before the
chapter test, making it seem more efficient to just lecture and show videos.
3. Large Class Sizes: Managing practical activities with very large class sizes can be
logistically challenging and pose significant safety concerns. It becomes difficult for a
