Scientific Method

Question 1

What is the first step of the scientific method?

Answer 1

asking testable questions

Question 2

What is a hypothesis?

Answer 2

is a possible explanation for something observed. Collected data can support or reject the hypothesis

Question 3

What is the third part of the scientific method?

Answer 3

Designing an experiment

Question 4

What are variables?

Answer 4

factors that can change in an experiment

Question 5

For valid research how many variables are purposely changed by the experimenter?

Answer 5

ONE

Question 6

What is the manipulated variable called?

Answer 6

The independent

Question 7

What is a dependent variable?

Answer 7

a variable that is expected to change as a result of what is being done by the researcher

Question 8

What are controlled variables?

Answer 8

they are all other factors that are kept the same between the different groups being tested

Question 9

What is stated first in the title of an experiment, the independent or dependent variable?

Answer 9

independent the dependent comes second

Question 10

How do you collect and interpret data?

Answer 10

facts figures and evidence from observations. May be quantitative or qualitative

Question 11

What quantitative data?

Answer 11

data that is measurements and/or numerical. It uses the International System of Units(SI), also called the metric system

Question 12

What is qualitative data?

Answer 12

data that does not use numbers

Question 13

What do I need to ask when drawing conclusions?

Answer 13

does the data support or reject the hypothesis?

Question 14

How do I communicate results?

Answer 14

share results with peers for their review. This may lead to new questions and further research.

Question 15

How does science develop?

Answer 15

scientific models, scientific laws and scientific theories

Question 16

What are Scientific theories?

Answer 16

an explanation for a wide range of observations that have never been rejected by experimentation. Theories may be rejected if future evidence does not support it.

Question 17

What are Scientific Laws?

Answer 17

a statement that tells what scientists expect to happen every single time under the same conditions. Ex. Law of Gravity

Question 18

What are Scientific Models?

Answer 18

a picture, diagram, computer image or other representation of an object that is impossible to observe.

Question 19

What is Science? What is Scientific Inquiry?

Answer 19

science is a way of learning about the natural world by gathering information. Information is collected by observing, inferring and predicting. Scientific Inquiry:the different ways the natural world is studied…the discovery of science.

Question 20

What is observing?

Answer 20

using your senses to gather information. Sight, hearing, touch, taste, and smell.

Question 21

What is inferring?

Answer 21

an explanation of your observations base on prior knowledge

Question 22

What is predicting?

Answer 22

forecasting what will happen in the future based on past experience or evidence

Question 23

What is Physical Science?

Answer 23

is the study of matter, energy, and the changes they undergo. Anything that has mass and takes up space is matter Energy is the ability to do work. There are two main areas of physical science: chemistry and physics

Question 24

What is Chemistry?

Answer 24

the study of the properties of matter and how matter changes

Question 25

What is Physics?

Answer 25

the study of how matter and energy interact
