Question

A science teacher encourages students to design their own experiment to test the effect of temperature on the rate of a chemical reaction. This activity primarily develops the students' understanding of science as:

• A. A fixed body of knowledge to be memorized
• B. A process of inquiry and a way of investigating
• C. A set of predetermined conclusions to be verified
• D. A rigid set of procedures that yields identical results

Answer 1

Answer:

B. A process of inquiry and a way of investigating

• Science is not just a collection of facts but a dynamic process.

• This process involves asking questions, forming hypotheses, designing experiments, collecting and analyzing data, and drawing conclusions.

• It emphasizes critical thinking and problem-solving skills.

• When students design their own experiment to test the effect of temperature on a chemical reaction's rate, they are engaging directly with the inquiry-based nature of science.

• They must first formulate a question (How does temperature affect reaction rate?).

• Then, they propose a testable hypothesis (e.g., Increasing temperature will increase reaction rate).

• The crucial step is designing the investigation: identifying variables (independent: temperature, dependent: reaction rate, controlled: concentration, pressure, etc.), choosing appropriate methods and equipment, and planning procedures to ensure reliability and validity.

• This hands-on experience transforms abstract scientific concepts into tangible investigative steps.
