1.
A hypothesis is:
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 about the outcome of an experiment or research study. Hypotheses are formulated based on existing knowledge and observations, and they are tested through experimentation or data analysis. The purpose of testing a hypothesis is to determine whether it is supported by evidence or if it needs to be revised or rejected. Therefore, a hypothesis is not a statement that is already proven true, but rather a statement that requires investigation and evidence to determine its validity.
2.
A science experiment should start with:
Correct Answer
A. A testable question
Explanation
A science experiment should start with a testable question because it helps to define the purpose and scope of the experiment. A testable question is one that can be answered through experimentation and observation. It allows the scientist to formulate a hypothesis, design a procedure, and collect data to support or refute the hypothesis. Without a testable question, the experiment lacks direction and may not yield meaningful results.
3.
The controls of an experiment:
Correct Answer
A. Are the part of the experiment that stays the same so you can compare changes.
Explanation
The controls of an experiment are the part of the experiment that stays the same so you can compare changes. This means that the controls are the variables or conditions that are kept constant throughout the experiment, while other variables are intentionally manipulated or changed. By keeping the controls consistent, any observed changes or effects can be attributed to the manipulated variables, allowing for a valid comparison and analysis of the experiment's results.
4.
A journal is written:
Correct Answer
B. During the experiment
Explanation
A journal is typically written during the experiment to record observations, data, and any other relevant information. It serves as a record of the experiment's progress, allowing the researcher to track and analyze their findings in real-time. Writing a journal during the experiment helps ensure accuracy and prevents important details from being forgotten. Additionally, it allows for the documentation of any unexpected occurrences or changes in the experimental procedure, which can be crucial for analysis and future reference.
5.
The conclusion of the scientific method.
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. It is the point at which the researcher analyzes the data collected and determines whether or not the research question has been answered. This is an essential component of the scientific method as it allows for the evaluation of the hypothesis and the drawing of conclusions based on the evidence gathered.
6.
A Variable is:
Correct Answer
C. Something that changes during an experiment
Explanation
A variable is something that changes during an experiment. In scientific research, variables are used to measure or observe the effects of different factors on the outcome of the experiment. These factors can be manipulated or controlled by the researcher to determine their impact on the dependent variable, which is the outcome or result being measured. By studying how variables change, scientists can gain a better understanding of cause and effect relationships and make informed conclusions about their experiments.
7.
Which step comes first in the scientific method?
Correct Answer
D. Problem
Explanation
In the scientific method, the first step is to identify the problem or question that needs to be answered. This step involves recognizing a specific issue or gap in knowledge that the scientist wants to investigate. Once the problem is clearly defined, the scientist can then proceed to formulate a hypothesis, design a procedure, collect data, and identify constants in order to systematically address and answer the problem or question at hand.
8.
The step in which you collect the information given by your experiment.
Correct Answer
A. Data
Explanation
Data refers to the information that is collected during an experiment. This step involves recording and organizing the measurements, observations, or any other relevant information obtained from the experiment. The data is typically collected in a systematic and organized manner to ensure accuracy and reliability. It serves as the foundation for further analysis and interpretation, allowing researchers to draw meaningful conclusions and make informed decisions based on the evidence obtained.
9.
The _________________ is the set of instructions that are followed while conducting an experiment.
Correct Answer
Procedure, procedure
Explanation
The term "procedure" refers to the set of instructions that are followed during the process of conducting an experiment. These instructions outline the steps and methods that need to be followed in order to carry out the experiment accurately and effectively. By following the procedure, researchers can ensure consistency and reliability in their experimental process, allowing for accurate data collection and analysis. The repetition of the word "procedure" in the question and answer reinforces the idea that the correct answer is indeed "procedure".
10.
The things in your experiment you keep the same in every trial.
Correct Answer
E. Constants
Explanation
In an experiment, constants refer to the things that are kept the same in every trial. These are the factors or variables that are intentionally held constant to ensure that they do not affect the outcome of the experiment. By keeping constants consistent, researchers can isolate the effects of the variable being tested and determine its true impact. Constants provide a baseline or control group against which the variable can be compared, allowing for accurate and reliable results.
11.
What skill is a scientist using when she listens to the sounds that whales makes?
Correct Answer
A. Making observations
Explanation
The skill that a scientist is using when she listens to the sounds that whales make is making observations. By actively listening to the sounds produced by whales, the scientist is gathering data and information about their communication patterns and behavior. This observation-based approach allows the scientist to gather empirical evidence and gain a deeper understanding of the whales' vocalizations and their significance in their natural habitat.
12.
Which of the following hypotheses is written correctly?
Correct Answer
D. If I freeze a tennis ball, then it will not bounce as high
Explanation
Option D is the correct hypothesis because it follows the proper "If... then..." format, which clearly defines the independent variable (freezing the tennis ball) and the dependent variable (how high it will bounce). This structure allows for a clear and testable prediction, which is essential for scientific inquiry. The other options are either incomplete, lack a clear comparison, or do not use the proper format for a hypothesis.
13.
A series of steps designed to help you solve problems and answer question is known as a:
Correct Answer
B. Experiment
Explanation
An experiment is a series of steps designed to help you solve problems and answer questions. It involves systematically testing a hypothesis or idea in order to gather data and draw conclusions. By following a set procedure, scientists can control variables and measure the effects of different factors to determine cause and effect relationships. This method allows for the replication of results and the advancement of scientific knowledge.
14.
All the things in an experiment that must be the same to make it fair are called:
Correct Answer
A. Controlled experiments
Explanation
In an experiment, controlled variables or constants are the things that must be kept the same in order to make it fair. These variables are controlled by the experimenter to ensure that any observed changes or effects are solely due to the independent variable being tested. By controlling all other factors, the experimenter can isolate the effect of the independent variable on the dependent variable and draw valid conclusions from the experiment. Therefore, controlled experiments involve manipulating the independent variable while keeping all other variables constant.
15.
When a scientist shares their findings with other scientists, they are:
Correct Answer
C. Communicating results
Explanation
When a scientist shares their findings with other scientists, they are communicating results. This involves conveying the outcomes of their research, including any discoveries, observations, or conclusions they have made. By sharing their results, scientists contribute to the collective knowledge and understanding of the scientific community, allowing others to build upon their work and potentially replicate or validate their findings. Communication is an essential aspect of the scientific process, as it fosters collaboration, peer review, and the advancement of scientific knowledge.
