Scientific Method

It is the first step of the Scientific Method:

• Forming a Hypothesis

• Stating the problem

• Stating a conclusion

• Gathering information

A hypothesis is a suggested solution

• True

• False

In any experiment, many variable are tested at a time.

• True

• False

A control Experiment: is run exactly the same ways as the experiment with the variable, but the variable is left out.

• True

• False

I want to do an experiment to prove if for a fire to be maintained, is necessary that oxygen is present. What is the variable of study?

• Oxygen

• A candle

• Matches

I want to do an experiment to prove if for a fire to be maintained, is necessary that oxygen is present. What is the Control experiment?

• An experiment involving oxygen

• An experiment not involving oxygen

• An experiment involving fire

• An experiment without fire

For an experiment to have a more accurate result, it is important to repeat the work several times.

• True

• False

Which is not a step of the scientific method

• Repeating the work

• Recording and analyze data

• Stating a conclusion

• Stating a Purpose

A possible explanation to a problem that has not yet been tested. 

• data
• theory
• hypothesis
• fact
