2. What is matter ? Solid Liquid Gas
A solid is shaped in a cube. The particles in the cube are packed closely together like an ice cube. The atoms also vibrate. Here are some few ex. of a solid. 1. ice cube 2. blocks 3. book 4. iPad 5. iPhone
Liquid
A liquid takes shape of a container. The particles in a liquid are farther apart and move more freely. Here are some few ex. of a liquid. 1. nail polish remover 2. hand sanitizer 3. soda 4. juice 5. blood
Gas
A gas is something that like fills the air. The particles in a gas move more rapidly and bounce around everywhere. Here are some few ex. of a gas. 1. when u spray perfume 2. steam 3. pollution 4. car gas 5. mist
Well matter is the space inside an object. Matter can be broken up into 3 (States of matter). Solid, Liquid, and Gas Siddique =

3. Physical Property Chemical Property
Physical property are characteristics that can be observed or measured without changing the substance.
Density
Fracture
Cleavlege
Color
Luster
A chemical property is used to characterize materials in reactions that change their identity.
Rusting
Color change
Temputure change
Flammable
Gas given off

4. Physical change Chemical change
A physical change is when the appearance or shape of a substance is changed.
Ripping paper
Ice cream melting
Freezing water
Boiling water
Cutting wood
A chemical change is how a substance reacts to another substance.
Burning wood
Burning gasoline
Rusting a pan
Burning paper
fireworks

5. What is an atom?
An atom is inside of matter. You cant break it down any further. The parts of and atom are neutrons, protons, and electrons. Even with a microscope you couldn’t see an atom, its to small. A neutron is neutrally charged. A proton is positively charged. Last, a electron is negatively charged.

6. What is an element?
An element is matter made up of only one kind of atom. There are 115 known elements and only 90 of them occur naturally on Earth.
Oxygen
Nitrogen
Silver
Aluminum
iron

7. What is a compound?
A compound is a substance who's smallest unit is made up of atoms of more than one element. More than one element is combined.
Water (H2O)
Hydrogen ( H2O2)
peroxide

8. Periodic table The periodic table organizes the elements
It also has a key to tell us what state of matter the element is in.
Additionally it lets u know what type of material is it.

9. The difference between them is that a substance is only one thing like water. A mixture would be a mix of things like salt water.
Substance
mixtures
A substance is matter that has the same fixed composition and properties.
Mixtures are combinations of substances that are not bonded together and can be physically separated.

10. Heterogeneous and Homogeneous mixture.
A Heterogeneous mixture is where the substances are not evenly mixed. We could see every individual part.
The seeds in a watermelon
The fruit in the fruit salad
The icing in the cake
The words on the book
The hair on the skin
A Homogeneous mixture contains 2 or more substances that are evenly mixed. We cant see each individual part.
ice cream
Pepsi
Juice
Soap
twisler

11. Solutions Solute Solvent
A solute is the substance that dissolves or seems to disappear.
Sugar
Baking soda
Salt
Kool aid powder
iodine
The substance that dissolves the solute is called solvent.
Water

12. What does solubility mean
Solubility is a measurement that describes how much solute dissolves in a given amount of solvent. Meaning that if there is more solute that solvent then it wont dissolve.
