8. A statement or an explanation of what
one has observed. They are intelligent
guesses.
9. Observation: The plant is planted
inside the bottle.
Inferences:
1.The plant’s leaves will turn
yellow, and eventually, it will die.
2. The plant will grow healthy.
10. A temporary explanation for an
observation that has to be tested.
“If .....then....” statement
11. Observation: The plant is planted inside the
bottle.
Inferences: 1.The plant’s leaves will turn yellow,
and eventually, it will die.
2. The plant will grow healthy.
Hypotheses: 1. If plant is planted inside
the bottle, the plant’s leaves will turn
yellow and will die eventually.
2. If plant is planted inside the bottle, the
plant will grow healthy.
13. Variables – any factor that can affect
the end result of an experiment.
14.
15. 1.Controlled Variable – the factor that
are the same
2. Manipulated Variable – the factor that has to
be tested
3. Responding Variable – the factor that affects
the result in an experiment
16. No Water
Plant 1 Plant 2 Plant 3
20 mL
Water
every
day
40 mL
Water
every
day
19. Things that might affect how tall
the plant grows could include:
1. the amount of light
2. the temperature of the air
3. the kind of soil
3. Controlled variables
21. What would the
manipulated variable
be in this experiment
on how much heat
different soils absorb?
What could be the
responding variable
in this experiment?
Remember you
should measure.
22. Look at the illustration at the right. Study how
hypotheses are formed.
Observation: The plant is planted inside the bottle.
Inferences: 1.The plant’s leaves will turn yellow, and
eventually, it will die.
2. The plant will grow healthy.
Hypotheses: 1. If plant is planted inside the bottle, the
plant’s leaves will turn yellow and will die eventually.
2. If plant is planted inside the bottle, then the plant will
grow healthy.
