Practice 2 - Developing and Using Models

Paul Anderson discusses the significance of models in science and engineering, differentiating between mental and physical models. He explains how models help in understanding phenomena and testing designs. The video emphasizes the importance of developing modeling skills from elementary to high school, using various tools and techniques. It also highlights the role of models in engineering for design testing and the educational progression in model usage.

What is a key limitation of mental models?

• They are unique to each individual.

• They are stable and consistent.

• They are always complete and effective.

• They are universally shared.

Which of the following is NOT a type of physical model?

• A diagram of DNA structure

• A mental image of the solar system

• A computer simulation of osmosis

• A mathematical formula like the ideal gas law

How are models used in engineering?

• To create mental images

• To test and build designs

• To replace physical experiments

• To eliminate the need for simulations

What is a benefit of using CAD software in engineering?

• It eliminates the need for physical prototypes.

• It is only useful for creating diagrams.

• It allows for the creation of mental models.

• It helps in building and testing designs virtually.

What is an effective way to introduce modeling to elementary students?

• Drawing and labeling parts of an insect

• Teaching advanced programming

• Using complex simulations

• Conducting crash tests

Which software is recommended for scientific modeling in schools?

• NetLogo

• Google SketchUp

• Photoshop

• AutoCAD

What is the purpose of competitions like mousetrap cars in education?

• To discourage teamwork

• To test students' memorization skills

• To encourage innovative model building

• To focus solely on theoretical knowledge
