Different types of Scientific Investigations
The scientist that discovered penicillin
A positive effect of technology on communication
Faster/global communication
Which part of a peer-reviewed scientific journal article contains a summary of the investigation?
Abstract
This type of variable is deliberately changed by the scientist.
Independent variable
Scientific investigations are described as this type of process because they are repeated and refined.
Continuous cycle
Which scientist tried to explain the colours of stars by using the star's observed frequency of light?
Doppler
The unintended negative consequence of technology on the environment
Environmental impacts (e.g. pollution, waste)
Evidence that supports or refutes a claim must be this to be valid.
reliable/credible
This variable is measured to assess the effect of the indepedent variable
Dependent variable
The step where scientists develop a possible explanation based on observations
Hypothesis.
The primary purpose of Eratosthenes' investigation was to determine
The circumference of the Earth.
Computer-generated environments used to test scientific ideas.
Simulations.
This type of evidence comes from experiments conducted by others
Secondary evidence
These variables must be kept constant to ensure a fair test.
Controlled variable
After analysing results, scientists often do this to improve their investigation.
Refinement or modification
Pasteur's work helped establish this theory
Germ Theory
Technology that improves precision by reducing human error
Automation
Large sample sizes improve this aspect of evidence
Reliable
Type of error affects results in a consistent direction
Systematic error
This step involves sharing findings with the scientific community
Communication or publication
This type of investigation combines multiple data sources and models
Modelling investigation
A limitation of relying heavily on technology in investigations
Potential bias, malfunction, over reliance on models
Rules and principles guiding responsible scientific practice
Ethics
A logical conclusion that goes beyond the data and suggests broader implications
Inference
Feedback from other scientists that leads to further investigation is known as..
Peer review
