In a controlled experiment, the variable that is changed to test the hypothesis is called the – (HINT: What did I change?)
Controlled Variable
Responsive Variable
Dependent Variable
Independent Variable
The factor in an experiment that you are counting or measuring is known as the:
Control
Independent Variable
Constant
Dependent Variable
A procedure carried out to gather data about an object or event.
evidence
inquiry
investigation
experiment
Which of these contains steps in the right order?
Ask a question, form a hypothesis, research, plan and conduct an investigation, draw conclusions, report and share results, make a conclusion
Form a hypothesis, ask a question, research, plan and conduct an investigation, draw conclusions, report and share results
Observe and ask questions, form a hypothesis, plan and conduct an investigation, draw conclusions, report and share results
Form a hypothesis, ask a question, research, report and share results, plan and conduct an investigation, draw conclusions
What step does every scientific experiment begin with?
hypothesis
question/observation
procedures
conclusion
Which are examples of renewable resources?
coal
wind power
solar power
water power
A goal of many environmental scientists is to understand and solve environmental problems by studying interactions between humans and the environment. This includes all of the following EXCEPT
How we use natural resources
How our actions alter our environment
How much we pay for resources
The study of how living things interact with each other and with their nonliving environment is called
ecology
biology
chemistry
physical science
Which of the following is a way that hunter-gatherers altered their environment?
polluting the air by burning fossil fuels
burning grasslands
clearing land for farms
finding new uses for solar energy
During which period in human history were most of our modern environmental problems introduced?
Hunter-gatherer
Agricultural
Industrial Revolution
Biotechnology Era
Which of the following is an environmental problem introduced during the Industrial Revolution? (Check ALL that apply)
pollution
loss of biodiversity
resource depletion
clearing of lands for growing crops
Which statement has the correct relationship between renewable and nonrenewable resources?
Renewable resources form at a much slower rate than nonrenewable.
Renewable and nonrenewable resources both form at approximately the same rate they are used
Nonrenewable resources form at a faster rate than renewable resources
Nonrenewable resources form at a slower rate than consumed, and renewable resources are replaced rather quickly by natural processes
Pollutants that can be broken down by natural processes are known as
biodegradable
renewable
nonrenewable
nonbiodegradable
The "Tragedy of the Commons" is the idea that
bad things happen to all people
people are not as careful with resources if they do not "own" them
people will be careful with the use of air and water since they are so important
as the world population increases so will the depletion of our resources
During an investigation you record the number of butterflies in your garden every day in June. This information that you are recording is your
observation
data
conclusion
analysis
You are finished with an investigation, so the next step is to look for a pattern between your independent and dependent variables. When you are looking for the pattern, you are
analyzing
forming your hypothesis
making your conclusion
establishing your control group
Which statement is true about the relationship between your data and your hypothesis?
Your data can prove your hypothesis is correct.
Your data can prove your hypothesis is incorrect.
Your data can support or refute your hypothesis, but can not prove it.
There is never a relationship between the data and hypothesis.
An inherited trait that increases an organism's chance of survival and reproduction in a certain environment (for example a sharp, strong beak that allows for tearing of flesh) is known as
an adaptation
a niche
commensalism
symbiosis
What is an example of artificial selection?
Letting dogs choose their own mate
Letting plants pollinate on their own
Crossing a labrador and a poodle to create a labradoodle
When humans select desirable traits to be passed down to offspring
natural selection
artificial selection
Which of the following are considered biodegradable? Check ALL that apply.
lead
food waste
paper
mercury
sewage
The productive area of Earth needed to support one person in a particular country is called the
sustainability factor
net domestic consumption
ecological footprint
tragedy of the commons factor
Sustainability is the condition in which human needs
may or may not be met
will be met at a standard of living similar to the current one for a person's lifetime
are met in such a way that a human population can survive indefinitely at a lower standard of living
are met in such a way that a human population can survive indefinitely at a standard of living similar to the current one
