Question

3.011) ___ are used to show what animals like dinosaurs looked like.
a. computer models
b. drawings
c. physical models
3.012) _ meteorologists use _ to show the possible path of a hurricane.
a. computer models
b. drawings
c. physical models
3.013) _ engineers use _ to design a new type of machine.
a. computer models
b. drawings
c. physical models
3.014) _ to save money and materials before building things, scientists might make a _.
a. drawing
b. table
c. graph
3.015) ___ which of these is an advantage of models?
a. they may not be accurate representations of the real thing.
b. they might not work well if they are too small, too big, or made of different materials than the real thing.
c. some models require a lot of computer power and time to run.
d. they allow scientists to observe things that are too small or too observe directly.
3.016) ___ which of these is a limitation of models?
a. they allow scientists to observe things that are too small or to observe directly.
b. they may not be accurate representations of the real thing.
c. they let scientists make predictions without doing real-work experiments.
d. they can be adjusted to see how changes in one factor af overall system.

Explanation:

• 3.011: Physical models are tangible representations. Dinosaurs are extinct, and physical models (like museum exhibits) show their appearance.
• 3.012: Meteorologists use computer models. These models use complex algorithms and data to predict hurricane paths.
• 3.013: Engineers use computer models. They can simulate designs, test functionality, and optimize before building physical prototypes.
• 3.014: Drawings are used to save money and materials. A drawing can convey design details without using resources for a full - scale build.
• 3.015: Models allow observation of unobservable things. This is a key advantage. Options A, B, and C are limitations.
• 3.016: Models may not be accurate. This is a limitation. Options A, C, and D are advantages.

Answer:

3.011 C. Physical models
3.012 A. computer models
3.013 A. computer models
3.014 A. drawing
3.015 D. They allow scientists to observe things that are too small or too observe directly.
3.016 B. They may not be accurate representations of the real thing.
