matter song
儿歌名称:matter song
歌词:
Matter has mass and takes up space
It’s everything you see, touch and taste
Matter is made of tiny molecules and atoms
Elements with protons, neutrons and electrons
Matter is the stuff that is all around
Scientists have found some things that don’t count
Matter cannot be a form of energy
Like wind, sound, light or heat
Matter has mass and takes up space
Solid, liquid, gas are the three different states
Matter has properties that tell what it’s like
It goes through physical and chemical changes, that’s right!
Solid, liquid, gas are the three different states
These phases of matter change what the matter makes
If water’s solid it’s ice, if it’s liquid it’s water
If the water is a gas then it turns to water vapor
Melting is going from a solid to a liquid
Evaporating is going from a liquid to a gas
Condensation is going from a gas to a liquid
Freezing is going from a liquid to a solid
Matter has properties that tell what it’s like
We make careful observations to help us describe
Mass, Volume, Density, and Pressure
Size, Shape, Texture, and Temperature
Properties of matter can be chemical
If oxidation takes place or if something is flammable
Matter can never be destroyed or created
A new substance can form with a chemical reaction
In a physical change, the object stays the same
You can fold it, bend it, cut it, but the object still remains
A physical change doesn’t really change the matter
The matter just moves from one state to another
In a chemical change, a new substance is created
You can rust it, burn it, cook it, but you can’t reverse it
In a chemical change something new will form
Energy is given off or energy is absorbed
