Question

question 4
why are models useful to scientists?
they allow scientists to measure very small things.
they help scientists stay safe during an experiment.
they always provide correct information.
they allow scientists to study very large or complex things.
question 5
which option is a scientific question?
how do rockets work?
do blue m&ms taste better than green m&ms?
how does the shape of a parachute affect its rate of fall?
what is your favorite color?

Explanation:

Question 4

Models in science are often used to simplify and represent very large or complex systems, phenomena or processes that might be difficult or impossible to study directly. They are not mainly for measuring small things, ensuring safety during experiments or always providing correct information (since they are simplifications and approximations).

Question 5

A scientific question is one that can be tested through experimentation, observation or data - collection. "How do rockets work?" is broad but can be explored scientifically. "Do blue M&Ms taste better than green M&Ms?" is subjective as taste is a personal preference. "How does the shape of a parachute affect its rate of fall?" is a testable question as variables like shape and rate of fall can be manipulated and measured. "What is your favorite color?" is a subjective, non - scientific question.

Answer:

Question 4

They allow scientists to study very large or complex things.

Question 5

How does the shape of a parachute affect its rate of fall?
