S. 4. 4.-Apply the scientific method to interpret a scientific investigation

Investigations

Science is propelled by this. Scientists determine hypotheses based on known evidence and then create these to test the hypothesis

Hypothesis

an informed guess about a causal relationship that is generated by observation and initial data collection

Hypothesis

This is testable and has the potential for being proven wrong. Scientists develop these only after they begin to have ideas about relationships. This could be from observations or background research on a topic/ is a guiding idea to develop a strong investigation or experiment

Evidence

During the investigation, the hypothesis will be accepted or rejected based on this collected from the investigation

Scientific hypothesis

prediction of what will occur in an experiment based on previous research

Independent, dependent, and control

3 types of variables

Dependent variable

what is measured after the independent variable is changed. It is the observed condition that responds to the manipulation of the independent variable

Controlled variables

All other variables should be kept the same in an investigation. These are called what such as temperature and humidity. Controlling all other variables helps to establish a causal relationship between the independent and dependent variables

Peer-reviewed

Scientists accept or reject their hypothesis or prediction based on the data to form a conclusion. Conclusions are thus based on evidence and then subjected to scrutiny but other scientists. Scientists can submit their evidence to professional journals, where the investigation and data are reviewed. Only the most reliable experiments and data will pass the review process and be published. This process is called what
