Matter
Grade 5 Science Inspire
Term | Definition |
---|---|
Mass | the amount of matter in an object, measured with a pan balance and gram weights |
Volume | the amount of space an object takes up, can be measured with graduated cylinder and milliliter (mL) larger objects have a greater volume |
Density | the amount of matter in a certain volume, found by dividing the mass of an object by its volume, less dense objects float |
Buoyancy | the upward push of a liquid or gas on an object placed on it, ability to float |
Weight | the gravitational pull on an object, objects with a large mass usually weigh a lot |
Matter | anything that has mass and takes up space, three common forms of matter are solids, liquids, and gases |
Physical Properties | can be observed without changing the kind of matter (ex. Color, texture, size) |
Chemical Properties | cannot be observed without changing the kind of matter (ex. Acidity, Corrosion, Combustion) |
Solution | is formed when a materials dissovles. Salt and sugar dissolves in water |
Element | a pure substance that cannot be broken down (ex. Aluminum, Helium, Cooper) |
Compound | combination of two or more elements (Water, Salt) |
Atom | the smallest unit of an element |
Molecule | a particle that contains more than one atom joined together |
Combustion | an explosion |
Corrosion | rusting. Like if you leave metal outside it turns a rusty color and an fall apart. |
Acidity | If you pour acid on a material the material will bubble and change chemically |
