Ch.1.2 Flashcards
What are conducted by scientists in order to find things out?
Scientific investigations.
What are the steps to conducting an experiment?
Observe, form a hypothesis, design and do experiment, analyse, draw a conclusion.
If the results of an experiment supports the hypothesis of a scientist, what happens?
The hypothesis becomes acceptable scientific knowledge.
What happens if the results of a scientific experiment doesn’t match the scientist’s hypothesis?
The science will modify thee hypothesis and start again.
What is science based on?
Evidence.
Name all the six science process skills.
Observing, classifying, designing experiments, communicating, doing experiments, inferring.
Name all the four types of scientific investigation.
Model building, fair tests, classifying and pattern seeking.
What do you call the factors of a fair test that affects the results?
A variable.
What is an independent variable?
It is the only variable that is changed in a fair test.
What is a dependant variable?
It is the variable to be measured in a fair test.
What are the controlled variables?
They are variables that are kept the same in a fair test.
When designing an experiment, we should ____________ all the variables and make sure the experiment is __________. Otherwise, the experiment results will not be_____________.
Identify, fair, reliable.
How do you classify?
Classifying involves comparing the similarities and differences between objects, and sorting those with similarities into groups.
How do you carry out pattern seeking?
Pattern seeking involves observing and recording natural phenomena, and trying to find a pattern. This type of investigation is common in astrology and geology.
How do you carry out model building?
Model building is another type of scientific investigation. In science, models can represent objects that are too small or too big to see.
