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.
