Slide 3 A graph shows that grass grows best at a temperature of 25 deg. C.

A.

The temperature is the dependent variable.
B.

The growth rate is the independent variable.
C.

The growth rate is the dependent variable.
D.

The temperature is the constant.

Correct Answer
C. The growth rate is the dependent variable.

Explanation
The graph shows that the temperature is being held constant at 25 deg. C, while the growth rate of the grass is being measured. This indicates that the growth rate is dependent on the temperature, as it is being affected by the different temperature levels.

Most data in science experiments can be graphed using which two main types of graphs?

A.

Bar graphs and point graphs
B.

Bar graphs and line graphs
C.

Line graphs and angular graphs
D.

Pie charts and cake graphs

Correct Answer
B. Bar grapHs and line grapHs

Explanation
Bar graphs and line graphs are the two main types of graphs commonly used to represent data in science experiments. Bar graphs are used to compare different categories or groups, where each category is represented by a separate bar. Line graphs, on the other hand, are used to show the relationship between two variables over a continuous interval. They are particularly useful for displaying trends or changes over time. Therefore, bar graphs and line graphs are the most appropriate choices for representing data in science experiments.

Predicting unmeasured data by extending the line of a graph is called....

A.

Forecasting
B.

Prognostication
C.

Extrapolation
D.

Graph prediction

Correct Answer
C. Extrapolation

Explanation
Extrapolation is the process of predicting unmeasured data by extending the line of a graph. It involves using the existing data points on a graph to make predictions about future or unobserved data points. By extending the line or curve of the graph, we can estimate values beyond the observed range. This technique is commonly used in various fields such as economics, statistics, and science to make projections and forecasts based on existing trends and patterns.

Slide 8 .O {font-size:149%;} When conducting science investigations, you should…

A.

Always show bias
B.

Show bias sometimes
C.

State your opinion in your theory
D.

Never show bias

Correct Answer
D. Never show bias

Explanation
When conducting science investigations, it is important to never show bias. Bias can influence the results and conclusions of the investigation, leading to inaccurate or unreliable findings. By remaining neutral and objective, scientists can ensure that their research is based on evidence and not personal opinions or preferences. This allows for more reliable and trustworthy scientific knowledge to be generated.

Slide 9 .O {font-size:149%;} Which one of these is NOT an opinion?

A.

The sky is blue.
B.

The sky is an awesome color in the morning.
C.

The sky is too bright.
D.

The sky is spooky at night.

Correct Answer
A. The sky is blue.

Explanation
The statement "The sky is blue" is not an opinion because it is a factual statement that can be objectively verified. Opinions are subjective and based on personal beliefs or feelings, whereas facts are based on evidence and can be proven true or false.

Slide 10 .O {font-size:149%;} Which one of these is NOT a good hypothesis?

A.

Bees cannot see purple.
B.

Purple flowers are best at attracting insects.
C.

Purple is a better color than pink.
D.

Sunlight must reflect purple light off purple objects.

Correct Answer
C. Purple is a better color than pink.

Explanation
The question asks for a hypothesis that is NOT good. The first three options provide testable hypotheses that can be proven or disproven through observation or experimentation. However, the fourth option, "Purple is a better color than pink," is not a testable hypothesis as it is subjective and cannot be objectively measured or proven.

Slide 11 Which one of these should never affect a scientific investigation?

A.

A stated hypothesis
B.

A religious belief
C.

The results of an experiment
D.

A data table from a series of measurements

Correct Answer
B. A religious belief

Explanation
A religious belief should never affect a scientific investigation because scientific investigations are based on empirical evidence, experimentation, and logical reasoning, while religious beliefs are based on faith and personal convictions. Scientific investigations rely on objective and verifiable data, while religious beliefs are subjective and often based on personal interpretations. Mixing religious beliefs with scientific investigations can lead to biased or unscientific conclusions, undermining the integrity and validity of the investigation. Therefore, it is important to keep religious beliefs separate from scientific investigations to maintain objectivity and ensure accurate results.

Slide 12 In doing scientific research, ethics should never be considered.

A.

True
B.

False

Correct Answer
B. False

Explanation
This statement is false because ethics should always be considered in scientific research. Ethical considerations ensure that research is conducted in a morally responsible manner, taking into account the potential impact on human subjects, animals, and the environment. Ethical guidelines help to protect the rights and welfare of individuals involved in research and promote the integrity and credibility of scientific findings. Ignoring ethics in scientific research can lead to harmful consequences and undermine the trust and legitimacy of the scientific community.

Slide 13 Which one of these is an example of technology?

A.

Research on the cause of lightning
B.

The invention of a lightning rod
C.

Studying how lightning causes thunder
D.

A study on the number of lightning strikes

Correct Answer
B. The invention of a lightning rod

Explanation
The invention of a lightning rod is an example of technology because it involves the creation and implementation of a device that utilizes scientific knowledge to protect buildings and structures from lightning strikes. Technology refers to the practical application of scientific knowledge and principles to solve problems or improve efficiency in various fields. In this case, the lightning rod is a technological solution designed to prevent damage caused by lightning strikes.

Slide 14 Which one of these is the result of science, not technology?

A.

An iPod
B.

A Refrigerator
C.

A light bulb
D.

A table of data

Correct Answer
D. A table of data

Explanation
A table of data is the result of science, not technology, because it is a representation of organized and analyzed information. Science involves the systematic study and understanding of natural phenomena, including collecting and analyzing data. In this case, the table of data is the outcome of scientific research or experimentation, where data has been collected, organized, and presented in a structured format. Technology, on the other hand, refers to the application of scientific knowledge for practical purposes, such as the development of devices like iPods, refrigerators, and light bulbs.

Slide 15 Which one of these is the highest form of scientific knowledge?

A.

Scientific law
B.

Scientific hypothesis
C.

Scientific theory
D.

Scientific guess

Correct Answer
C. Scientific theory

Explanation
A scientific theory is considered the highest form of scientific knowledge because it is a well-substantiated explanation of some aspect of the natural world that is based on a vast amount of evidence, experimentation, and observation. It is a comprehensive explanation that has been extensively tested and confirmed through various scientific methods and is widely accepted by the scientific community. A scientific theory is more than just a guess or hypothesis; it is a well-established and reliable explanation that can be used to make predictions and further advance scientific understanding.

In graphing, the axis that runs from left to right along the bottom of the graph is is the ____ axis.

A.

Horizontal
B.

Vertical
C.

Diagonal
D.

Primary

Correct Answer
A. Horizontal

Explanation
The correct answer is horizontal because in graphing, the axis that runs from left to right along the bottom of the graph is called the horizontal axis. This axis is used to represent the independent variable or the variable being measured or controlled. It is also known as the x-axis and is typically labeled with values or categories.
