QUESTION 11. There are several types of practical activities. Demonstrate your
understanding of demonstrations, experiments and practical investigations. The
information should include the following:
Understanding Practical Activities in School Science
Practical activities are essential components of the science curriculum, allowing
students to engage actively with scientific concepts. They can be broadly categorized
into demonstrations, experiments, and practical investigations.
1. Demonstrations
Example:
Activity: Using a ripple tank to demonstrate constructive and destructive interference
of two pulses.
Role of the Learner:
Learners watch the demonstration, observe the phenomena, ask and answer
questions, and possibly record observations or measurements.
Role of the Teacher:
The teacher prepares and conducts the demonstration, explains the purpose, and
provides commentary on techniques, safety considerations, and theoretical context.
The teacher may also facilitate a discussion to reinforce understanding.
Important Element to Consider:
Visibility: Ensuring that all students can clearly see the demonstration is crucial,
especially in larger classes. Proper setup and possibly using visual aids or technology
can enhance visibility and engagement.
2. Experiments
Example:
Activity: Electric circuits with resistors in series and parallel – measuring potential
difference and current.
Role of the Learner:
Learners follow detailed instructions to conduct the experiment, handle equipment,
make observations, take measurements, and record data. They may also analyze the
results and draw conclusions.
Role of the Teacher:
The teacher introduces the experiment, explains the theory behind it, provides clear
instructions, prepares and sets up the necessary equipment, and supervises the
learners' work. The teacher also moves around to assist learners and ensures safety
protocols are followed.
, Important Element to Consider:
Time Management: Adequate time must be allocated for students to complete the
experiment, including setup, conducting the experiment, and a concluding discussion.
This ensures that learning objectives are met and students fully understand the
theoretical concepts.
3. Practical Investigations
Example:
Activity: Investigate conservation of linear momentum.
Role of the Learner:
Learners engage in the entire scientific process, from identifying a problem and forming
a hypothesis to designing and conducting an experiment, making observations, and
drawing conclusions. They take more initiative and responsibility compared to other
activities.
Role of the Teacher:
The teacher guides the learners through the scientific process, provides initial input on
defining the problem, and offers varying levels of guidance based on the learners'
capabilities. The teacher ensures that the investigation stays on track and that students
are using proper scientific methods.
Important Element to Consider:
Scientific Process Engagement: Learners must be encouraged to fully engage with
each step of the scientific process, from hypothesis formation to conclusion. This not
only reinforces practical skills but also deepens their understanding of scientific inquiry
and critical thinking.
