- use careful observations and measurements to develop descriptive findings about an organism, substance, reaction, or natural process
- can include both quantitative and/or qualitative data
- include the following parts of scientific inquiry:
- observations
- scientific research question
- procedure
- data, graphs, analysis
- conclusion
- do not include hypothesis or predictions
- can be identified with the following key words:
- observe
- describe
- list
- identify
- Example: observing cells under a microscope and diagramming what is seen
- involve collecting data on different organisms/objects/features, or collecting data under different conditions (e.g., times of year, temperatures, locations) to make comparisons
- involve looking for patterns or trends by comparing similarities and differences over time and under various circumstances
- include the following parts of scientific inquiry:
- observations
- scientific research question
- hypothesis
- procedure
- variables (independent and dependent)
- data, graphs, analysis
- conclusion
- do not include a control group
- can be identified with the following key words:
- compare/contrast
- similarity/difference
- categorize
- Example: comparing two different types of leaves to see which one has a greater rate of transportation
- involve a process in which a "fair test" is designed and variables are actively manipulated, controlled, and measured in an effort to gather evidence to support or refute a causal relationship
- involve determining how a variable affects a control and experimental group
- include the following parts of scientific inquiry:
- observations
- scientific research question
- hypothesis
- procedure
- variables (independent and dependent)
- control and experimental group
- data, graphs, analysis
- conclusion
- can be identified with the following key words:
- control and experimental groups
- constants
- testing the effects of …
- Example: testing to see how the height of a ramp effects how far a marble will roll
