Science Final

What Topics do I need to know for the Final?

QuestionAnswer
Steps of the Scientific Method? Ask a question, form a hypothesis, test the hypothesis, analyze the results, draw conclusions, communicate results
Mass? The amount of matter an object is made of
Volume The amount of space something takes up
Density the amount of matter in a given space d=m/v
Physical properties matter that can be observed or measured without changing its identity
Physical changes a change that affects 1 or more physical properties of a substance
chemical changes occurs when a substance changes into something with different properties
chemical properties describes a substance based on its abilities to change properties
freezing liquid to a solid
melting solid to a liquid
condensing gas to liquid
boiling high temp. in a liquid
changes of state (of matter) conversion of a substance from one physical form to another
sublimation solid to gas
vaporization liquid to gas (must be boiling)
evaporation liquid to gas (not boiling)
Boyle's laws states that when something's pressure goes up its volume goes down
Charle's laws states that when something's temp goes up so does its volume
Elements pure substance that can not be separated or broken down
atoms atomic # (top #)
protons # of atoms (+ charge)
neutrons atomic weight atomic weight - # of protons
electrons # of protons (- charged )
mixtures 2 or more elements that are not chemically combined
compound 2 or more elements that are chemically combined
work when a force causes an object to move in that direction w= f x d work= joules
power the rate at which work is done p= w/t
solute dissolved to form a solution
solvent substance in which solute is dissolved
solutions appears to be a single substance but is not
solubility amount of solute needed to make a saturated substance
homogeneous mixture a mixture that is in uniform
heterogeneous mixture doesn't have a uniform and has different properties
suspensions mixture of materials that are dispersed through out
colloids particles that are not heavy enough to settle out
alloys solid solutions of metals or nonmetals that are dissolved
simple machines lever, inclined plane, wedge, screw, wheel and axle, pulley, compound machine
compound machine 2 or more simple machines working together
kinetic energy energy of motion ke= mv ^2 / 2
potential energy energy of position or shape p=w x h
newton's first law object at rest stays at rest, object in motion stays in motion / unless a force is acted upon it.
newton's second law states that the acceleration of an object is dependent upon two variables- the net force acting upon the object and the mass of the object
newton's third law states that for every action (force) in nature there is an equal and opposite reaction
renewable replaced naturally in nature/ reusable
nonrenewable will eventually run out
metals good conductors, shiny, pound able
metalloids some characteristics of metals- not all
non- metals no characteristics of metals
ductility ability to be drawn or pulled into a wire
malleability ability to be pounded into thin sheets
conductivity electricity can pass through them
speed how fast something is done s=d/t
velocity speed within a direction v= d/t
acceleration the rate of which velocity changes a= final v - starting v / time it takes to change
friction the rubbing together of two objects

Use these flashcards to help memorize information. Look at the large card and try to recall what is on the other side. Then click the card to flip it. If you knew the answer, click the green Know box. Otherwise, click the red Don't know box.

When you've placed seven or more cards in the Don't know box, click "retry" to try those cards again.

If you've accidentally put the card in the wrong box, just click on the card to take it out of the box.

You can also use your keyboard to move the cards as follows:

If you are logged in to your account, this website will remember which cards you know and don't know so that they are in the same box the next time you log in.

When you need a break, try one of the other activities listed below the flashcards like Matching, Snowman, or Hungry Bug. Although it may feel like you're playing a game, your brain is still making more connections with the information to help you out.

To see how well you know the information, try the Quiz or Test activity.
