TermDefinition
mass ​How​ ​much​ ​matter​ ​is​ ​in​ ​something:​ ​ ​Measured​ ​in​ ​grams​ ​(triple​ ​beam balance,​ ​pan​ ​scale)​ ​ ​It​ ​always​ ​stays​ ​the​ ​same.
volume ​How​ ​much​ ​space​ ​something​ ​takes​ ​up.​ ​Measured​ ​in​ ​liters​ ​or​ ​milliliters uses a ​Graduated​ ​cylinder
temperature How​ ​hot​ ​or​ ​cold​ ​something​ ​is​ ​in​ ​Celsius. Uses a thermometer!
buoyance ​Able​ ​to​ ​float​
density ​The​ ​amount​ ​of​ ​molecules​ ​in​ ​matter​ ​that​ ​allow​ ​it​ ​to​ ​float​ ​or​ ​sink
weight ​ ​The​ ​measurement​ ​of​ ​the​ ​pull​ ​of​ ​gravity​ ​of​ ​an​ ​object
physical properties ​Parts​ ​of​ ​an​ ​object​ ​that​ ​can​ ​be​ ​observed​ ​during​ ​the​ ​five senses
phases​ ​or​ ​states​ ​of​ ​matter​ solid, liquid, gas
matter ​Anything​ ​that​ ​has​ ​mass​ ​and​ ​takes​ ​up​ ​space​ ​(​ ​solid,​ ​liquid​ ​gas)
solid Definite​ ​size​ ​and​ ​shape.The​ ​molecules​ ​are​ ​packed together​ ​tightly.
liquid Definite​ ​size,​ ​but​ ​not​ ​a​ ​define​ ​shape. Takes the shape of the container.
gas No definite​ ​size​ ​or​ ​shape.​ ​ ​The​ ​molecules​ ​are​ ​far apart​ ​and​ ​move​ ​rapidly.

freezing​ ​point​ ​of​ ​wat​er 0 degrees Celsius
mixture ​Two​ ​or​ ​more​ ​substances​ ​that​ ​mixed​ ​together​ ​but​ ​can​ ​be​ ​separated---physical properties stay the same
solution ​Two​ ​or​ ​more​ ​substances​ ​that​ ​when​ ​mixed​ ​together​ ​can​ ​NOT​ ​be separated---physical properties change
dissolve ​To​ ​add​ ​solid​ ​or​ ​gas​ ​to​ ​a​ ​liquid​ ​so​ ​that​ ​the​ ​particles​ ​get​ ​so​ ​small​ ​you can​ ​no​ ​longer​ ​see​ ​them
ingredients​ ​The​ ​individual​ ​substances​ ​added​ ​to​ ​a​ ​mixture
classify to put into groups
investigation ​The​ ​scientific​ ​process​ ​used​ ​to​ ​answer​ ​questions​ ​by​ ​collecting data;​ ​you​ ​change​ ​one​ ​variable​ ​and​ ​everything​ ​else​ ​stays​ ​the​ ​same
energy the ability to do work or cause change
mechanical energy energy produced by a moving part or machine
kinetic energy energy in motion
potential energy energy at rest
electrical energy movement of charged particles
light energy energy that allows our eyes to see
thermal energy energy that causes a transfer of heat

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.
