Engineering and Science Concepts Assessment

Module 1 of the middle school science preparation for the Praxis covers the nature of science and engineering, highlighting their differences and similarities. It explains the scientific method and engineering design process, emphasizing empirical evidence and problem-solving. The module also addresses safety and emergency procedures in lab settings, including equipment use and maintenance.

What is the primary goal of science?

• To create new technologies

• To gain knowledge about the natural world

• To solve engineering problems

• To develop new products

How does engineering primarily differ from science?

• Engineering is about applying knowledge to solve problems

• Engineering is purely theoretical

• Engineering focuses on gaining knowledge

• Engineering does not involve any design process

What is empirical evidence?

• Evidence that is based on assumptions

• Evidence that is purely theoretical

• Evidence based on personal beliefs

• Evidence that is observable and measurable

What is a key characteristic of scientific concepts?

• They are fixed and unchangeable

• They are only applicable to physics

• They are developed quickly

• They are subject to revision with new evidence

What is the first step in the engineering design process?

• Creating a hypothesis

• Defining the problem

• Testing the solution

• Conducting experiments

What does the iterative nature of engineering involve?

• Focusing only on theoretical knowledge

• Ignoring constraints and criteria

• Modifying and testing designs repeatedly

• Repeating the same design without changes

Why is safety equipment important in a lab setting?

• To reduce the cost of experiments

• To protect individuals from potential hazards

• To ensure experiments are conducted faster

• To enhance the appearance of the lab

What should be considered when storing chemicals in a lab?

• The brand of the chemicals

• The temperature and light exposure

• The size of the storage room

• The color of the containers

What is a crucial aspect of handling emergencies in a lab?

• Using any available equipment

• Relying solely on students for safety

• Having a clear evacuation plan

• Ignoring minor injuries

What is the role of personal protective equipment (PPE) in a lab?

• To make experiments more interesting

• To protect against potential hazards

• To reduce the need for supervision

• To increase the speed of experiments
