matter- anything that has mass and takes up space

mass- is the amount of mattersomething has in it

volume- the amount of spacematter takes up

volume- the amount of space matter takes up

You can calculate volume by multiplying the length of an object times its width times its height.

volume- the amount of space matter takes up

You can also calculate volume by water displacement:

If the water in the graduated cylinderstarts at 200 mL, and goes up to 300mL when you add a coin, you can tell the coin’s volume must be????

length- how long something is

width- how wide an object is

height- how tall something is

weight- the measure of the force of gravity between an object and the Earth.

Click the picture for a cool tutorial on mass vs. weight.

Click the box below to calculate your weight on other planets.

property- characteristics; words we use to describe something/matter

graduated cylinder - a tall, thin container used to measure the volume of liquids.

beaker- shorter, fatter (than graduatedcylinders) cylindrical containers used to measure the volume of liquids

measuring cup – cups with markings to measure the volume of liquids.

liters/milliliters- metric units for measuring the volume of liquids

milliliter=mL

liter = L

balance scale- a tool used to measure the mass of an object

grams/kilograms- metric unitsused to measure mass

A 1 liter bottle of water has a mass of 1kg.

A dime or a paper clip has a mass of 1g.

meters/centimeters- metric units used to measure length/height/width

Doorways are oftenabout 1m across Your pinky finger is

about 1cm across.

density – a way of describing matter in which you tell how massive something is for its size

Click the picture below to watch a video of an experiment that brings everything together – air pressure, density, and volume.

How Dense Are Solids, Liquids, and Gases?

What does density have to do with sinking andfloating?

Click the picture below to do an online lab and test objects to see if they will float.

An object will float if it is less dense than the liquid in which it is placed.

buoyancy – an object’s ability to float

Click the picture below to watch a video on buoyancy.

conduct/conductor- to conduct meansto allow energy to flow through/a conductoris a material that allows energy to floweasily.

insulate/insulator – to insulate is toprevent energy from moving freely/an insulator is a material that preventsenergy from flowing freely

Some insulators:rubberplasticwoodcloth

physical change- a change that doesn’t really change the matter in an object

physical change- a change that doesn’t really change the matter in an object

chemical change – a change that results in the formation of new chemical substances
