Scientific Method
An educated guess
hypothesis
This is the varaible changed by the investigator
The independent variable.
What is seen during the experiment that is measured with your senses or a tool.
Observation
An educated guess based upon a prediction that can be tested.
Hypothesis
All the biotic and abiotic factors in an area.
Ecosystem
A method used by scientists to answer an investigativ3e question.
Scientific method
This variable is recorded as data in the data table.
Dependent Variable
An explanation made about the observation.
Inference
A factor that is held constant in an investigation, it doesn’t change.
Controls
Biosphere
The earth and all it’s biomes or regions.
After a hypothesis is made, scientists usually do this...
Experiment
These stay the same in an investigation
Controls
Data that describes what is sensed by the senses, describes the quality of something. IE: The music made them feel happy.
Qualitative Data
A group of organisms that are all the same.
Population
Biome
A region of earth that varies in climate from other areas.
Analyze data
Jessie and James wanted to know how the color of light affects plant height. What is the independent variable in this investigation?
Color of Light
Data that describes what is sensed by the senses, describes the quality of something. IE: The music made them feel happy.
Quantitative Data
A group of organisms that are different from one another.
Community
How do biotic and abiotic differ from one another?
Biotic=living
Abiotic=nonliving
Writing a scientific conclusion
Sally and Stevie wanted to know how the type of material the ball was made of affected how high it bounced. What is the dependent variable?
How high the ball bounced
The most logical explanation of why something happens in science, strongly supported by multiple lines of evidence.
Scientific theory
How do a population and community differ from one another?
Populations=same organims
Communities=different organisms
Put the following in order from largest to smallest:
Biome, Population, Community, Biosphere, Ecosystem, Organism
Biosphere, Biome, Ecosystem, Community, Population, Organism
Remember: BBECPO!
