Practice quiz to review scientific method

• 1.

### "What effect does temperature have on plant height?" is an example of a conclusion.

• A.

True

• B.

False

B. False
Explanation
This statement is not an example of a conclusion. It is actually an example of a question or a hypothesis, as it poses a query about the relationship between temperature and plant height. A conclusion, on the other hand, is a final statement or judgement reached after considering evidence or arguments. Therefore, the correct answer is false.

### The manipulated variable is purposely changed to test a hypothesis.

• A.

True

• B.

False

A. True
Explanation
The statement is true because in an experiment, the manipulated variable, also known as the independent variable, is deliberately altered or changed by the researcher in order to investigate its effect on the dependent variable. This manipulation allows the researcher to test their hypothesis and determine the relationship between the variables under study. By intentionally changing the manipulated variable, the researcher can observe and analyze the resulting changes in the dependent variable, leading to a better understanding of the cause-and-effect relationship between the variables.

### Gram is the unit used to measure the mass of an object.

• A.

True

• B.

False

A. True
Explanation
The given statement is true because gram is indeed the unit used to measure the mass of an object. The gram is a metric unit of mass in the International System of Units (SI). It is commonly used to measure the mass of small objects or substances. Other common units of mass include kilogram, pound, and ounce, but gram is specifically used as the base unit for mass measurement.

• 4.

### The graduated cylinder is the most appropriate tool used to measure length.

• A.

True

• B.

False

B. False
Explanation
The graduated cylinder is not the most appropriate tool used to measure length. A graduated cylinder is actually used to measure volume, not length. To measure length, a ruler or a tape measure would be more appropriate tools. Therefore, the correct answer is False.

Rate this question:

• 5.

### The inch is the most appropriate unit to measure the length of a swimming pool.

• A.

True

• B.

False

B. False
Explanation
The inch is not the most appropriate unit to measure the length of a swimming pool because it is a very small unit of measurement. Swimming pools are typically much larger in size, and using inches to measure their length would result in very large numbers. It would be more practical to use a larger unit such as feet or meters to measure the length of a swimming pool.

Rate this question:

• 6.

### The hypothesis is the curved surface of a liquid.

• A.

True

• B.

False

B. False
Explanation
The hypothesis is not the curved surface of a liquid. A hypothesis is a proposed explanation or prediction based on limited evidence or observations, which can be tested through further investigation. It is a tentative statement that can be either true or false depending on the evidence and data collected. The curved surface of a liquid is not a hypothesis but rather a physical property or characteristic of liquids. Therefore, the correct answer is false.

• 7.

### This is used to solve questions/problems

scientific method
Explanation
The scientific method is a systematic approach used to solve questions or problems in a scientific manner. It involves making observations, formulating a hypothesis, conducting experiments or gathering data, analyzing the results, and drawing conclusions. This method allows scientists to gather objective and reliable information, test hypotheses, and make evidence-based decisions. It is a widely accepted and effective approach in various scientific fields, helping to ensure accuracy and reproducibility in research.

### Data is displayed here to show patterns or trends or results from the experiment.

graph
Explanation
A graph is a visual representation of data that is used to display patterns, trends, or results from an experiment. It allows for easy interpretation and analysis of the data by presenting it in a clear and organized manner. Graphs can be used to compare different variables, track changes over time, or illustrate relationships between variables. In this case, the data is displayed in a graph to showcase any patterns, trends, or results that may be present.

Rate this question:

• 9.

### Using one or more of your senses to gather information

observations
Explanation
Observations involve using one or more of our senses to gather information. By observing, we can gather data about our surroundings, events, or objects. This process allows us to perceive and understand the world around us, and it forms the basis for scientific inquiry and research. Through observations, we can gather empirical evidence, make predictions, and draw conclusions. It is an essential skill in various fields such as biology, psychology, and astronomy, enabling us to study and analyze phenomena objectively.

• 11.

### Part of the procedure that has no treatment, used to make comparisons

control group
Explanation
A control group is a part of a procedure that does not receive any treatment or intervention. It is used to establish a baseline for comparison in order to evaluate the effectiveness or impact of a specific treatment or intervention. By comparing the outcomes of the control group to those of the experimental group, researchers can determine if the treatment had any significant effect. The control group helps to isolate and identify the specific effects of the treatment being studied.

### The  is purposely changed to test a hypothesis.

manipulated variable
Explanation
The manipulated variable is purposely changed in an experiment to test a hypothesis. This variable is the one that the researcher intentionally alters or controls in order to observe its effect on the dependent variable. By manipulating this variable, the researcher can determine if there is a cause-and-effect relationship between the manipulated variable and the outcome of the experiment.

Rate this question:

• 14.

### is the metric unit used to measure mass

gram
kilogram
Explanation
The metric unit used to measure mass is either the gram or the kilogram. The gram is the smaller unit and is commonly used for measuring small objects or quantities. The kilogram is the larger unit and is used for measuring larger objects or quantities. Both units are widely used in scientific and everyday applications to accurately measure the mass of objects.

Rate this question:

• 15.

### Data is recorded in a  and displayed in a  .

data table
graph
Explanation
Data is recorded in a data table, which is a structured format that organizes information into rows and columns. This allows for easy comparison and analysis of the data. On the other hand, the data can also be displayed in a graph, which visually represents the data points and trends. Graphs are useful for identifying patterns and trends that may not be immediately apparent in a data table. Therefore, both a data table and a graph are effective tools for presenting and analyzing data.
