Test Review : Chapter 1 Scientific Method

Chemistry

Scientific Method

Conclusion

The result or results based on what you have seen as the outcomes of

an experiment is called the:

control variable

The part of the experiment which is held constant and used as a

comparison is called the:

Data

It is important that one records observations and measurements.

These records are known as:

dependent variable

The part of the experiment which is measured, is a result of the change

in the independent variable, and makes up the Y-axis of a graph is

called the:

Experiment

In order to test an educated guess, one sets up or develops a(n) :

What are the three parts of an experiment?

1)Procedure

1)Procedure2)Variables

1)Procedure2)Variables3)Conclusion

Hypothesis

The idea or educated guess based on patterns of observation.

Other names for hypothesis?

Deduction , educated guess, idea, possible solution, and prediction

are all examples of a(n):

independent variable

The part of the experiment which is manipulated by the experimenter

and makes up the X-axis of a graph is called the:

Observations

The act of using senses to gather information is called :

Placebo

A fake drug or medication used as a control is an example of the use of

a (n):

Problem

The first step in the scientific method is to clearly state the :

procedure

The organized method in which an experiment is done is referred to as

the:

Retest

The experiment must always work under the given conditions.Redo it over and over for correct

results

Revise

If experiment does not work then changes are made. Change the hypothesis, procedure, or go

back and make more observations and change what is

to be solved

Scientific Method

The orderly process gone through by scientists in order to find solutions to problems and to

discover answers to questions is known as the:

Theory

The general belief and best explanation for natural

phenomenon based upon observable facts and

experimentation is called a(n) :

Variables

The experimental factors or what varies in an experiment.

3 Types of variables?

Independent, dependent, and control are all examples of:

List in order and briefly describe the 6 steps of the scientific method.

1st Step =

1) Problem: What is solved

List in order and briefly describe the 6 steps of the scientific method.

2nd Step =

1) Problem: What is solved*2) Observation: Using your senses

List in order and briefly describe the 6 steps of the scientific method.

3rd Step =

4th Step =

5th Step =

1) Problem: What is solved 2) Observation: Using your senses 3) Hypothesis: Educated guess 4) Experiment: Test hypothesis*5) Retest/Revise: Redo / Change

List in order and briefly describe the 6 steps of the scientific method.

6th Step =

1) Problem: What is solved 2) Observation: Using your senses 3) Hypothesis: Educated guess 4) Experiment: Test hypothesis 5) Retest/Revise: Redo / Change*6) Theory: Hypothesis that withstands repeated testing, Final and best explanation

The following statements are examples of the use of the Scientific Method. What is the correct step?

Heat on the bottom glass tube causes the air to expand, the liquid to rise, and the birds head to dip into the

water. The moist tip makes the top of the “bird” cooler and keeps the

liquid rising.

Theory

The following statements are examples of the use of the Scientific Method. What is the correct step?

I redid my experiment several times using different cups and later changed my procedure by adding salt to the cups.

Retest / Revise

The following statements are examples of the use of the Scientific Method. What is the correct step?

I think there was something in the cup that made the water

disappear.

Hypothesis

The following statements are examples of the use of the Scientific Method. What is the correct step?

There was a beaker of water and three red cups. The water was poured in the

three cups and on the third trial it disappeared.

Observations

The following statements are examples of the use of the Scientific Method. What is the correct step?

To test my prediction I heated the bottom of the “birds” and pulse glass with the

heat of my hand and observed the results.

Experiment

The following statements are examples of the use of the Scientific Method. What is the correct step?

What makes the bird move, and what happened to the water?

Problem

The following statements are examples of the use of the Scientific Method. What is the correct step?

Step 1) Redo the first experimentStep 2) Replace the red cups with

clear cupsStep 3) Pour water into each cupStep 4) Turn cup upside down

and record results
