what is "hypothesis
a special type of scientific investigation that is performed under controlled conditions, usually in a laboratory.
a plan for asking questions and testing possible answers.
a possible logical answer to a scientific question, based on scientific knowledge.
A hypothesis MUST include
that, maybe, cause
if, then, because
what, so, because
then, because, if
Give an example of an hypothesis
if you don't water your plant then it won't grow because plants need water
Plant growth is not affected by light colors
Plants will not grow if it is not watered
all plants die eventually
what is a "prediction"
a broad explanation for events that is widely accepted as true.
a statement that tells what will happen under certain conditions.
a possible logical answer to a scientific question, based on scientific knowledge.
a possible logical answer to a scientific question, based on scientific knowledge.
what is "evidence"
any type of data that may either agree or disagree with a prediction, conclusions may be formed by evidence
a possible logical answer to a scientific question, based on scientific knowledge.
a special type of scientific investigation that is performed under controlled conditions, usually in a laboratory.
a possible logical answer to a scientific question, based on scientific knowledge.
what is "a experiment"
a special type of scientific investigation that is performed under controlled conditions, usually in a laboratory.
a change in species over time.
any type of data that may either agree or disagree with a prediction,
a possible logical answer to a scientific question, based on scientific knowledge.
A(n) ________ generally tests how one variable is affected by another.
Scientific investigation
Experiment
The _______ _____ in an experiment directly affects the interpretation of the results.
scientific theory
sample size
cell theory
scientific investigation
what is "repetition"
any type of data that may either agree or disagree with a prediction, so it may either support or disprove a hypothesis.
states that all living things are made up of cells, and living cells always come from other living cells.
a change in species over time.
the repeating of an experiment, validating the results. With repeated testing, some hypotheses may eventually become scientific theories
what is "scientific theory"
a broad explanation for events that is widely accepted as true.
a statement that tells what will happen under certain conditions.
states that all living things are made up of cells, and living cells always come from other living cells.
a change in species over time.
