Exploration 2 Lesson 2 Class Activity

What is the main difference between how scientists and engineers approach problems?

• Scientists ask questions, engineers seek solutions.

• Scientists seek solutions, engineers define problem.

• Scientists use models, engineers carry out investigations.

• Scientists analyze data, engineers design solutions.

What are models used for in scientific investigations?

• To test proposed solutions.

• To determine criteria and constraints.

• To make predictions and account for variables.

• To analyze and interpret data.

In engineering, prototypes are primarily used for:

• Testing design solutions and communicating ideas.

• Forecasting weather and climate changes.

• Determining tensile strength of materials.

• Breaking down problems into smaller parts.

What is the importance of planning in scientific investigations?

• To analyze and interpret data accurately.

• To communicate information clearly.

• To ask questions and determine investigation methods.

• To develop explanations based on analyzed data.

How are the results of tests and data analyzed in engineering?

• By graphing data to compare measurements.

• By developing explanations based on structure.

• By engaging in arguments based on reason and evidence.

• By clearly stating the results for other scientists and engineers.

What does it mean to engage in an argument from evidence?

• To disagree with others based on personal opinions.

• To support a statement with data and reasoning.

• To communicate information clearly and precisely.

• To analyze and interpret data accurately.

What should be included when communicating the results of an investigation?

• An explanation of how the results match predictions.

• An argument based on personal opinions.

• Criteria and constraints of the solution.

• A demonstration of how to repeat the investigation.

What is the main purpose of analyzing and interpreting data in scientific investigations?

• To communicate information clearly to others.

• To develop explanations based on analyzed data.

• To test proposed solutions and improve designs.

• To forecast weather and climate changes accurately.

How do scientists and engineers use arguments in their work?

• To disagree and create conflicts.

• To support their ideas with reason and evidence.

• To communicate information to other scientists and engineers.

• To determine the cost constraints of a solution.

What is the purpose of communicating information in scientific investigations?

• To analyze and interpret data accurately.

• To argue based on reason and evidence.

• To evaluate results and repeat the investigation.

• To communicate design ideas and improve solutions.
