SCIENCE OUTCOMES 14,15

Fair Tests

Independent variables are deliberately changed

Dependent variables are the change that happens in the experiment

(observations)

Controlled variables are all other variables that should be kept same

Scientific Reports

A hypothisis is an educated guess

An aim is what you set out to do

Materiels is what are requiered in the process

The method is the steps in experiment

The result is is is the outcome (could be shown as graph, table ect.)

The conclusion is how the experiment ended up as

The discussion is ideas and suggestons about results

Results

Graphing

Bar

Coloum

Line

Piechart

- can also use tables

Scientific Drawings

- makr sure to use:

a sharp pencil

a ruler

and LABLE!!

The Basic Requirements for Humans

Air as we need oxygen to survive

Water as we need to be hydrated

Nutrience as we need food

Characteristics of Living Things

M ovement

R espiration

S timiulis

G rowth

R eproduction

E xcertion

N utrition

Resources- Materials Humans Make use of

a resourse is any MATERIALS that humans make use of

materiels are NOT devices or machiens

classified as either NATUTRAL or MAN-MADE

NATURAL occouring resources are produced by living things or found in nature

Most NATURAL resources are mostly prossesed before hand

MAN-MADE resources require a chemical process

MAN-MADE can be traced back to to natural resources

Recources- Where They Occour

Our planet is devided into four sections called spheres.

ATMOSPHERE is the air surrounding our planet

HYDROSPHERE is all the water

LITHOSPHERE is the earths crust

BIOSPHERE is where living things occour

Matter

any substance that takes up SPACE and have VOLUME

we use word 'STUFF'

fire, thoughts, feelings, energy are NOT matter

matter is studied by PHYSISTS

PROPITIES are fetures or characteristics of a substance

most matter is in SOLIDS, LIQUIDS or GAS

THESE ARE THE 3 STATES OF MATTER

the branch of science that studies matter is called PHYSICS

Solids

have a fixed volume

fixed shape

does not flow

cannot be compressed

particles are held tightly together

do not change places

Liquids

fills its shape

it flows

cannot be compressed

particles are tight but can change places

fixed volume

Gass

fills as much space as it can around them

can be compressed

dose not flow

particles are spread out and move frequently

fixed volume

Changing States

Diagram above shows how the states of matter change.
