What is the essence of science
Knowledge of the pysical world
Scientific method
Process of investigation in which problems are identified and their suggested explanations are tested by carrying out experiments
Observation
When something is noticed
Hypothesis
Ah educated guess based on observations
Experiment
Designed to test the hypothesis
Data
Info collected on experiments
Scientific journals
Journals where procedures and results are often published
Theory
Is a hypothesis that had been supported by many different experiments
Control
Is used to provide a comparison against which the actual experiment is being judged
Replicate
When an experiment is repeated
Who had the original Petri dish
Alexander Fleming
Ethics
Related to whether fornicate is right or wrong
Scientific method is based in 6 things, name them..
- Making observations
- Making a hypothesis
- Carrying out experiments
- Recording results
- Forming a conclusion
- Changing of accepting the hypothesis based on the conclusion
Principle or law
Arises from a theory when it is seen always to be true under all conditions over a long period of time
Name the steps in scientific method
Observation Hypothesis Experiment Data Conclusion Relating the conclusion to existing knowledge
Name the reasons for experiments to be fair
Sample size
Random selection
Double blind testing
Replicates
Sample size
Normally as large as sample as possible is tested for more reliable results
Random selection
To prevent bias (unfairness) by the person carrying out the experiment
Double blind testing
Prevents person carrying out experiment from unconsciously influencing the results
Replicated
Repetition of a test/ complete experiment
Name the four principles of experiments
Careful planning and design
Ensure experiment is safe
Design a control experiment
Experiments must be fair
Explain extent of our knowledge
The ability to form a hypothesis and design an experiment is dependent on the amount we know relating to our observations
Give an example of change in the new work
Antibiotics
Two features of good experimental design
Large sample size
Control experiement
Scientific research published
Scientific journal
Limitations of sci meth
Interupting results
Poor investigation
