Scientific Method

Back 1

is an organized set of investigation procedures.

Front 2

Scientific Methods =]

Back 2

1.State the problem
2.Gather info
3.Form a hypothesis
4.Test the hypothesis
5.Analyze data
6.Draw conclusions

Front 3

State the problem

Back 3

The question of "how" or "why" something occurs is the problem.

Front 4

Gather Information

Back 4

Finding info & learning as much as possible about the background of the problem.

Front 5

Form a hypothesis

Back 5

Making your own hypothesis, which is a possible explanation for a problem using what you know or observed.

Front 6

Testing a Hypothesis

Back 6

A common way to test a hypothesis is to make an experiment.

Front 7

Analyzing data

Back 7

recording observations and recording data into easy-to-read graphs & tables.

Front 8

Drawing conclusions

Back 8

based on your analysis of your data, you decide if your hypothesis is supported.

Front 9

experiment

Back 9

tests the effects of one thing on another using controlled conditions.

Front 10

Variable

Back 10

factor that can cause a change in the results of an experiment.

Front 11

Dependent Variable

Back 11

is the amnt. of growth because its value changes according to changes in other variables.

Front 12

Independent Variable

Back 12

the variable u change to see how it will affect the dependent variable

Front 13

constant

Back 13

is a factor that does not change when other variables change.

Front 14

control

Back 14

is the standard by which the test results can be compared.

Front 15

bias

Back 15

occurs when what the scientist expects changes how the results are viewed.

Front 16

Model

Back 16

represents an idea, event or object to help ppl understand it.

Front 17

Theory

Back 17

an explanation of things or events based on knowledge gained from many observations and investigations.

Front 18

Scientific Law

Back 18

Statement about what happens in nature that seems to be true all the time.

Front 19

Technology

Back 19

An application of science to help people.

Front 20

precision

Back 20

description of how close measurements are are to each other.

Front 21

Accuracy

Back 21

comparing a measurement to to the real or accepted value.

Front 22

kilo

Back 22

means 1000

Front 23

1km

Back 23

=1000 meters

Front 24

Length

Back 24

distance between two points (SI unit is meter)

Front 25

Mass

Back 25

measurement of the quantity of matter in an object
SI unit is kilograms

Front 26

Time

Back 26

interval for two events
SI unit is seconds

Front 27

Temp

Back 27

how cold or hot something is
SI unit is Kelvin

Front 28

Conversion Factor

Back 28

ratio that is equal to one and is used to change one unit to another.

Front 29

Volume

Back 29

Amount of space occupied by an obj.
V=(L)(W)(H)
The SI unit is always cubed.

Front 30

Absolute Zero

Back 30

coldest possible temp on the Kelvin scale. 0 degrees k
Celsius is -273 degrees.

Front 31

Graph

Back 31

visual display of info/data

Front 32

Line Graph

Back 32

shows how a relationship of two variables changes over time.
x-axis is indep. variable
y is dependent v.

Front 33

bar graph

Back 33

useful for comparing info collected by counting

Front 34

circle graph

Back 34

shows the diff parts of a whole quantity.

Front 35

Science

Back 35

way of learning abt the natural world

Front 36

scientific laws ( notice the diff (sssss))

Back 36

are repeated patterns in nature

Front 37

standard of measurement

Back 37

exact quantity that ppl agree to use as a basis of comparison.

Front 38

When a standard of measurement is established

Back 38

all measurements r compared to the same exact quantity --the standard.

Front 39

you have to determine the angles of your data to create a
