Anthing that has mass and takes up space
conductors of electricity and heat, can be shaped into sheets, can be shaped into sheets or wire, solids, have gray color, can reflect light, shiny
Atomic Theory
The particles are packed closely together, they do not move, just vibrate
The atoms are connected differently
Physical properties
A balance
Temperature
Cut it into pieces, peel the skin, etc.
You bake a cake with it
Solid, liquid, and gas
Melting
Evaporation
Condensation
Liquid and Gas
when different materials are placed together but each material keeps it's own properties(can be separated)
Answers will vary. Example: Cheerios, strain the cereal from the milk
Solute
Solution
Use a magnet to separate the paper clips. Use a strainer to separate the cheerios and milk.
Physical Change
Chemical Change
Physical changes may happen more or less easily depending on temperature. Example: Butter is easier to spread when it is warm.
Particles move faster as the temperature rises, they can rearrange themselves into new substances quickly.
The medicine in the bottle may change if it is heated.
