1.Formulating Hypothesis

3.Controlling variables

2.Interpretingdata

The ability to use our five senses. Seeing Tasting Hearing Feeling Smelling

Observing

Observation:

The plant is planted inside the bottle.

The ability to tell something about an object observed.

Describing

Looking into the similarities or differences of objects or organisms (color, size, shape)

Comparing

Foretelling or forecasting future events.

Ex. It will rain.

Predicting

A statement or an explanation of what one has observed. They are intelligent guesses.

Inferring

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.

A temporary explanation for an observation that has to be tested.

“If .....then....” statement

Hypothesizing

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.

A way to test a hypothesis.

Experimenting

Variables – any factor that can affect the end result of an experiment.

Controlling Variables

1.Controlled Variable – the factor that are the same

3 Kinds of Variables

2. Manipulated Variable – the factor that has to be tested

3. Responding Variable – the factor that affects the result in an experiment

No Water

Plant 1 Plant 2 Plant 3

20 mL

Water every day

40 mL

Water every day

1. Manipulated variable

Amount of water that the plant receives each day.

2. Responding variable

Height of the plant

Things that might affect how tall the plant grows could include:

1. the amount of light 2. the temperature of the air3. the kind of soil

3. Controlled variables

PLASTIC CUP OF HOT WATER

STYROFOAM CUP OF HOT WATER

What is the manipulated variable in this experiment on keeping water hot?

What might be the responding variable in this experiment? Remember you should measure.

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.

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.
