QUESTION 1

1. Explain each step of the general form of practical activities and how you
would secure it by using a practical example for each step.

In practical science activities, there are several key steps that teachers must
follow to ensure students understand both the process and the underlying
concepts. Here’s an explanation of each step in general form and how to secure
it with an example for each:

1. Introduction and Contextualization
This is the first step where the teacher introduces the purpose of the activity. The
teacher sets the context by explaining the relevant theory or concept that the practical
activity aims to demonstrate or verify.

Example: Before conducting an experiment on resistors in series and parallel circuits,
the teacher would explain Ohm’s law and the basic concepts of electrical resistance,
potential difference, and current. This provides learners with the theoretical framework
they need to understand the experiment’s purpose.

2. Defining the Problem or Hypothesis
The teacher defines a clear objective or question that the practical activity aims to
address. This step frames the investigation and aligns it with specific learning
outcomes.

Example: In a practical investigation of conservation of linear momentum, the teacher
might pose the question: “Does the total momentum of objects before a collision equal
the total momentum after the collision?” This hypothesis will guide the students’
