Answer 1

Here are the correct responses to each of your questions:

Question 1 Why is it important to form a hypothesis when conducting a scientific investigation?

• A hypothesis offers a testable statement that guides the direction of the experiment.

Question 2 Which of the following is NOT a limitation of science?

• Science is always changing. (This is a characteristic of science rather than a limitation.)

Question 3 Which of the following best describes the dangers of handling corrosive materials in a laboratory?

• Corrosive materials can damage and destroy living tissues upon contact, as well as corrode metals and other materials.

Question 4 Which of the following is a scientific statement?

• Water boils at 100 degrees Celsius at standard atmospheric pressure.

Question 5 Why is it necessary to test a hypothesis in scientific research?

• To collect data that can confirm or contradict the hypothesis.

Question 6 What is the best definition of a scientific theory?

• A well-substantiated explanation of an aspect of the natural world that is based on a body of evidence and has been repeatedly confirmed through observation and experimentation.

Question 7 Why can scientists never prove a theory absolutely?

• Because new evidence or observations could potentially contradict or modify the theory.

These answers reflect the principles of scientific inquiry and methodology.
