 Question 1

1. Explain the following concepts or terms in your own words and indicate the unit and page
numbers in the study guide where you found the theory for answering this question.

1.1. Application

The term "application" in the context of practical science refers to the use of scientific knowledge
and skills to solve real-world problems. This involves applying theoretical concepts learned in the
classroom to practical situations, which can help reinforce understanding and demonstrate the
relevance of scientific principles to everyday life.

(Study Guide - Page: 35-36)

1.2. Learning the scientific approach

Learning the scientific approach involves understanding how scientists investigate the natural world.
This approach is characterized by forming hypotheses based on pre-conceived ideas, conducting
experiments to test these hypotheses, and critically evaluating the results to avoid biases. It
emphasizes the importance of unbiased observations and plausible reasoning within the given
context.

1.3. The extent to which practical work develops big ideas

Practical work in science education helps develop big ideas by allowing students to engage in
hands-on activities that illustrate fundamental scientific concepts. This approach can help students
understand the cause-and-effect relationships in scientific phenomena and see the practical
implications of theoretical knowledge. It also reinforces the big ideas of science through direct,
personal experience and experimentation.

1.4. The use of models

Models are physical or conceptual representations used to explain and visualize abstract scientific
ideas. They help simplify complex systems, making them easier to understand and manipulate. In
teaching, models can be used to demonstrate concepts like molecular interactions or the behavior of
particles, aiding in the comprehension of theoretical concepts through tangible examples.
