Scientific Process
What variable is the scientist changing in an experiment?
What is environmental science?
The scientific study of Earth's environment and solutions to environmental problems
Natural Resources are resources humans can use but cannot create.
Which era involved nomadic people collecting and tracking animals for consumption?
Hunter-gatherer era
What are the 4 major environmental problems?
Climate Change
Pollution
Loss of Biodiversity
Resource Depletion
What variable is the scientist measuring in an experiment?
Dependent Variable
What is an ecological footprint?
The amounts of resources needed for one person to survive. Measures how fast we consume resources and generate waste compared to how fast nature can absorb our waste and generate new resources.
What are renewable resources?
Resources that can be replenished if used in a sustainable way
To assume control over the reproduction and care of plants and animals. This happened during the Agricultural revolution.
Paper is consider __________pollution, meaning it can break down by biological processes whereas plastic is considered _________pollution because it cannot break down by biological processes.
Paper is consider biodegradable pollution, meaning it can break down by biological processes whereas plastic is considered non-biodegradable pollution because it cannot break down by biological processes.
What variable is the scientist keeping constant or the same in an experiment?
Control Variable
How can you reduce your Ecological Footprint?
Use only the resources you truly need, and avoid wasting resources
Using resources in a sustainable way
What are non-renewable resources?
How did the industrial revolution begin most of our environmental problems?
Industrial Revolution involved was when machinery began to replace human and animal labor
Fossil fuels used increasingly for energy.
What could a continued loss of biodiversity cause to happen to a species?
Extinction
Lisa is working on a science project. Her task is to answer the question:
"Does Rogooti (a hair cream sold on TV) affect the speed of hair growth (in length)". Her family is willing to volunteer for the experiment.
What is the independent variable in the experiment?
The Rogooti hair cream
Which description represents quantitative data? Explain.
A. Seventy three percent of people prefer hot Drake over Kendrick in a student survey
B. The flowers contain pollen and have a sweet smell
C. The bumblebee is yellow and black
D. There are majority tall students at North Cobb High School
A. Seventy three percent of people prefer hot Drake over Kendrick in a student survey, this data is quantitative because it describes the data using words
There are two types of natural resources. Which natural resource contributed to the most environmental problems?
Non-renewable resources such as fossil fuels (oil, natural gas, coal)
How has the Medical Revolution impacted the Environment? (Name more than one way)
People are living longer, healthier lives, using more resources
Why are Greenhouse gases like Carbon Dioxide an environmental problem?
Greenhouse gases such as Carbon Dioxide are an environmental issue because they cause energy to be trapped close to Earth’s surface, warming Earth’s climate, which is the leading cause of climate change.
Mr. Burns believes that giving his workers free lunch will improve the productivity at the plant. At the end of the month, he measures productivity by examining the number of completed jobs.
What is the dependent variable in this scenario?
The work productivity or number of completed jobs
An organized way of using evidence to study the natural word. What term best fits this description?
Science
What would make a renewable resource no longer renewable?
When that resource is no longer used in a sustainable way where it is available for other uses.
In what 3 ways has the Technological Revolution impacted the human population and natural resources?
Human population is increasing, standards of living are increasing, and natural resources are decreasing.
What are the three impacts from having a loss of biodiversity?
The loss of some species may affect others and disrupt entire ecosystems
Humans rely on different species for food, oxygen, and medicine,
The greater the diversity of a community & population, the better chance they have of surviving potentially catastrophic events such as natural disasters, climate change, and deadly disease.
