Questions and Answers

1.

A hypothesis is:
- A.
  
  A statement that is true.
- B.
  
  A statement that needs to be proved right or wrong.
- C.
  
  What the experiment is all about.
Correct Answer
B. A statement that needs to be proved right or wrong.

Explanation
A hypothesis is a statement that needs to be proved right or wrong. It is an educated guess or prediction that is based on existing knowledge or observations. It is an essential part of the scientific method and serves as a starting point for conducting experiments and gathering evidence to support or refute the hypothesis. The process of testing the hypothesis allows scientists to gain a better understanding of the phenomenon being studied and contributes to the advancement of scientific knowledge.

A science experiment should start with:
- A.
  
  A research question
- B.
  
  A hypothesis
- C.
  
  The procedure
Correct Answer
A. A research question

Explanation
A science experiment should start with a research question because it helps to identify the problem or topic that needs to be investigated. The research question guides the entire experiment by providing a clear focus and objective. It serves as the foundation for the development of a hypothesis, which is a proposed explanation or prediction based on existing knowledge or observations. Once the research question and hypothesis are established, the procedure can be designed to test the hypothesis and collect data. Therefore, a research question is the logical starting point for a science experiment.

The controls of an experiment:
- A.
  
  Is the part of the experiment that stays the same so you can compare changes.
- B.
  
  Is the part of the experiment that will change.
- C.
  
  Is the part of the experiment that makes everything work.
Correct Answer
A. Is the part of the experiment that stays the same so you can compare changes.

Explanation
The controls of an experiment refer to the part that stays the same throughout the experiment. This allows for a comparison of any changes observed in the variables being tested. By keeping the controls constant, any differences in the experimental group can be attributed to the independent variable being tested. The controls provide a baseline for comparison and help ensure that any observed effects are not due to other factors.

A journal is written:
- A.
  
  Before the experiment
- B.
  
  During the experiment
- C.
  
  After the experiment
Correct Answer
B. During the experiment

Explanation
During the experiment, researchers typically keep a journal to record their observations, data, and any unexpected findings. This allows them to document the progress of the experiment in real-time and keep track of any changes or developments. By writing a journal during the experiment, researchers can ensure accuracy and provide a detailed account of their methodology and results. This journal serves as a valuable resource for future reference and analysis, helping to establish the credibility and reproducibility of the experiment.

The conclusion of the scientific method:
- A.
  
  Includes the research question to start the experiment.
- B.
  
  Includes the list of experiments.
- C.
  
  Includes the answer to the research question.
Correct Answer
C. Includes the answer to the research question.

Explanation
The conclusion of the scientific method refers to the final outcome or result of the experiment, which addresses the research question. It is the answer or solution that is derived from the experiments conducted. The conclusion summarizes the findings and provides insight into whether the initial hypothesis was supported or rejected. It is an essential part of the scientific method as it helps to draw meaningful conclusions and contribute to the overall understanding of the research topic.

6.

In which step, the hypothesis is formed?
- A.
  
  Step 1
- B.
  
  Step 4
- C.
  
  Step 5
- D.
  
  Step 6
Correct Answer
B. Step 4

Explanation
In Step 4, the hypothesis is formed. This step is usually part of the scientific method or research process, where the researcher collects data and analyzes it to form a hypothesis. The hypothesis is a proposed explanation or prediction based on the available evidence. It is an educated guess that can be tested and further investigated in subsequent steps.

7.

The measurable factor in an experiment is known as the:
- A.
  
  Dependent variable
- B.
  
  Independent variable
- C.
  
  Controlled variable
- D.
  
  None of the above
Correct Answer
A. Dependent variable

Explanation
The measurable factor in an experiment is known as the dependent variable. This variable is the one that is being observed and measured to determine the effect of the independent variable. It is called "dependent" because its value depends on the changes made to the independent variable. The controlled variable, on the other hand, is kept constant throughout the experiment to ensure that any changes observed in the dependent variable are solely due to the independent variable.
