False, there is a fourth state of matter called plasma.
True, condensation occurs when water vapor particles touch a cold surface and their temperature drops.
Heating the water in the first beaker causes the water to evaporate, forming water vapor. In water vapor the particles are far a part.

Objective:
Investigate the properties of solutions and provide evidence whether mixtures can be separated based on the properties of their parts

Explain your results:
3. Magnetism, the ability to attract objects using a magnet.
4. Density made it possible. The plastic paper clips separate because they float.
Density: How much mass of a substance in a given space or volume.

12. Different materials are placed together.
Chapter 1- Lesson 4: What are mixtures and solutions?
Mixtures:
A mixture
Different materials are placed together.
Each material keeps its own properties.
A combination of materials that are not chemically combined.

13. Chapter 1- Lesson 4: What are mixtures and solutions?
Examples:
Name mixtures that combine 2 states of matter?
Mud is made up of sand (solid) and water (liquid).
Seltzer water (soda water) is made of CO2 (gas) and water (liquid).

Separating Mixtures
The physical properties of a substance can be used to separate it from a mixture.
Magnets can be used to separate metals from nonmetals
A screen filter can be used to separate sand and pebbles ( smaller particles go through the screen filter, but the pebbles do not).
Pebbles: small smooth stones.

3. Classify:
Pour through a strainer (sieve)
Use a magnet.
4. Challenge:
Pour the mixture into water, the hollow beads float. So you can scoop them out of the water.
Hollow: having a hole or empty space inside.

6. Infer:
A mixture of 2 or more substances does not form a new substance with new properties.
Hollow: having a hole or empty space inside.

How can a recycling center separate a mixture of iron and aluminum cans?
They could use a magnet to separate the iron cans.
Hollow: having a hole or empty space inside.

21. Chapter 1- Lesson 4: What are mixtures and solutions?
A solution is a type of mixture in which substances are spread out evenly and will not settle down.

22. solute + solvent= solution
Chapter 1- Lesson 4: What are mixtures and solutions?
Solutions
In a solution:
The substance that is dissolved is called a solute.
The substance in which the solute is being dissolved is called a solvent.
solute + solvent= solution
