SCIENCE- semester 1

SCIENCE OUTCOMES 14,15Fair 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

ResultsGraphing Bar Coloum Line Piechart - can also use tablesScientific 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

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 OccourOur 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.
