A teacher is doing an activity on density. Students observe that a steel spoon sinks in water but a steel bowl floats. She asks students, ‘why do you think the bowl did not sink ? What will make it sink ?’ Which of the following process skills is the teacher trying to develop among her learners ?

Correct Answer: Hypothesizing

Explanation:
In science education, process skills are fundamental tools and cognitive processes that students use to gather information, construct knowledge, and solve problems.

Let us analyze the teacher's action and questions:

1. Observation: The students already observed a phenomenon (a steel spoon sinks, but a steel bowl floats).
2. Teacher's Questions: She asks, “Why do you think the bowl did not sink? What will make it sink?”

When students are asked “why do you think...” or to predict “what will make it sink,” they are encouraged to form tentative explanations, educated guesses, or testable predictions based on prior knowledge and current observations. Formulating a tentative explanation or proposed solution to a phenomenon is known as hypothesizing.

Why other options are incorrect:
• Observing: Observing involves using the senses to gather direct information about an object or event (e.g., noting that the spoon sinks while the bowl floats). The teacher's question goes beyond just observing; it asks for reasons and predictions.
• Experimenting: Experimenting is the process of testing a hypothesis by carrying out a procedure under controlled conditions. The students are not yet carrying out a test; they are being prompted to think of reasons and predictions first.
• Inferring: While inferring involves drawing conclusions based on observations, asking open-ended exploratory questions about "what will make it sink" specifically invites proposed testable conditions, which targets the skill of hypothesizing.

Therefore, the teacher is primarily trying to develop the skill of hypothesizing among her learners.
