Decide if each of the following statements is true.If it is not rewrite the parentheses part to make it true.

1) Scientific methods include observation,(forming a hypothesis, and experiment).
ans: false ;answer questions; solve problems

2)A statement that can be tested and presents a possible solution to a question is a(law).
answer:False; theory.
:3) In a controlled experiment, two groups are tested and allconditions except (two) are kept the same for both groups.

answer:False ;One

4)A condition that remains the same for both groups is called the (independent variable.)

answer:False; controlled experiment

5)A condition that changed by experimenter in one group and not the other is called the (dependent variable).
answer: true
6)A scientific experiment can be conducted(only in a laboratory).
Answer:False; anywhere

7)A theory is a (law) that has been confirmed by many experiments.
answer:True

!. true/ The scientific method does include hypothesis, experiment, observation.

2. hypothesis is a statement that can be tested. A law is already verified.

3. ok

4. ok

5. You change the independent variable while holding controlled variables constant.

6. ok

7. A law is a theory that has been confirmed by many experiments. (for example Newton's laws of motion.)

To determine whether each statement is true or false, we need to understand the concepts involved and analyze the options given. Let's go through each statement and explain how to arrive at the correct answer:

1) Scientific methods include observation, (forming a hypothesis, and experiment).
- The correct answer is False because while observation is a part of the scientific method, forming a hypothesis and conducting experiments are also important components. However, scientific methods also involve asking questions and solving problems. So, the correct answer would be: Scientific methods include observation, asking questions, and solving problems.

2) A statement that can be tested and presents a possible solution to a question is a (law).
- The correct answer is False because a statement that can be tested and presents a possible solution to a question is known as a hypothesis, not a law. A law, in scientific terms, is a well-established principle that describes a phenomenon. So, the correct answer would be: A statement that can be tested and presents a possible solution to a question is a hypothesis.

3) In a controlled experiment, two groups are tested, and all conditions except (two) are kept the same for both groups.
- The correct answer is False because in a controlled experiment, all conditions except one are kept the same for both groups. This one varied condition is known as the independent variable. So, the correct answer would be: In a controlled experiment, two groups are tested, and all conditions except one are kept the same for both groups.

4) A condition that remains the same for both groups is called the (independent variable).
- The correct answer is False because the condition that remains the same for both groups is called the controlled variable or constant. The independent variable is the condition that is deliberately changed by the experimenter in one group and not the other. So, the correct answer would be: A condition that remains the same for both groups is called the controlled variable or constant.

5) A condition that is changed by the experimenter in one group and not the other is called the (dependent variable).
- The correct answer is True because the condition that is changed by the experimenter in one group and not the other is indeed called the dependent variable. It is the variable that is measured or observed to determine the effect of the independent variable. So, the given statement is already true.

6) A scientific experiment can be conducted (only in a laboratory).
- The correct answer is False because a scientific experiment can be conducted anywhere, not just in a laboratory. While some experiments may be conducted in controlled laboratory settings, others can take place in the field or even in everyday life situations. So, the correct answer would be: A scientific experiment can be conducted anywhere.

7) A theory is a (law) that has been confirmed by many experiments.
- The correct answer is True because a theory is a well-substantiated explanation based on repeated experimentation and observation. It is more comprehensive than a law, as it provides a broader framework to explain a range of related phenomena. So, the given statement is indeed true.

By analyzing the concepts and considering the correct definitions, we can determine whether each statement is true or false.
