Scientific method and Engineering Design process

What is the Scientific Method?

• A systematic process used for scientific investigation, involving observation, hypothesis formation, experimentation, and conclusion.

• A random approach to solving problems without any structured process.

• A method used exclusively in laboratory settings for conducting experiments.

• A way to gather data without any form of analysis.

What are quantitative observations?

• Observations that involve measurements and can be expressed in numbers.

• Observations based on personal feelings and opinions.

• Observations that cannot be measured or counted.

• Observations that are only qualitative in nature.

What is a conclusion in the Scientific Method?

• A summary of the results of an experiment, determining whether the hypothesis was supported or not.

• A detailed explanation of the experimental procedure used.

• A list of all the materials required for the experiment.

• An introduction to the background information related to the experiment.

What is experimentation in the Scientific Method?

• The process of testing a hypothesis by conducting controlled tests and collecting data.

• A method of making observations without any testing.

• A way to prove a theory without any evidence.

• The act of guessing the outcome of a scientific inquiry.

What is the Engineering Design Process?

• A method for engineers to create new materials and products.

• A series of steps that engineers follow to come up with a solution to a problem, including defining the problem, brainstorming, designing, building, testing, and improving.

• A process that only focuses on the testing phase of engineering projects.

• A set of guidelines for engineers to follow when working in teams.

What is a dependent variable?

• The variable that is manipulated in an experiment.

• The variable that is kept constant throughout the experiment.

• The variable in an experiment that is measured or observed to see how it changes in response to the independent variable.

• The variable that determines the outcome of the experiment.

What is the first step in the Scientific Method?

• Making observations and asking questions about a phenomenon.

• Formulating a hypothesis based on previous knowledge.

• Conducting experiments to test the hypothesis.

• Analyzing data and drawing conclusions.

What are qualitative observations?

• Observations that describe qualities or characteristics and cannot be expressed in numbers.

• Observations that can be measured and expressed in numerical values.

• Observations that are based on personal opinions and feelings.

• Observations that are made using scientific instruments.

What is an independent variable?

• The variable that is measured in an experiment.

• The variable that is kept constant throughout the experiment.

• The variable in an experiment that is deliberately changed or manipulated by the scientist.

• The variable that is affected by the independent variable.

What is iteration in the Engineering Design Process?

• The process of repeating steps in the design process to improve the solution based on testing and feedback.

• A method of creating a final design without any revisions.

• A technique used to eliminate all errors in the design process.

• The initial phase of the design process where ideas are generated.
