15 Questions
What is a life-size model?
A model with the same size and proportions as the actual item it represents
What is an advantage of physical models?
They are used for testing predictions which can save time, money, and lives
What is a limitation of physical models?
They cannot be used to study everything
What are some examples of physical models mentioned in the text?
Bridges, cell models, and models of buildings
Why are physical models commonly used in classrooms?
Because they aid in clearer communication and better understanding
What is the purpose of a model bridge being built on a small scale?
To test for safety before building the actual bridge
What is a disadvantage of physical models mentioned in the text?
They are not the cheapest way to visualize things
Why is testing a model safer than doing a real-life test?
Because models can save time, money, and lives by testing predictions
What is the key distinction between a physical model and a scale model?
A physical model can be seen and touched, while a scale model is smaller or larger than the real object but maintains the same proportions.
What is the correct method to scale a smaller object into a larger model?
Multiply the actual object by the scale in which the model is planned to show.
What is the primary purpose of a scale model?
To represent an object with the same proportions as the real object, but in a different size.
What is the benefit of a physical model with moving parts?
It allows for a better understanding of how the parts of an object interact.
Why are scale models useful for studying objects that are too large or too small to study directly?
They provide a manageable representation of the object for study or demonstration.
What is the correct method to scale a large object to a smaller model?
Divide the actual object by the scale in which the model is planned to show.
What is the defining characteristic of a life-size model?
It is the same size as the real object it represents.
