Sci. Blitz Day 1

Properties of Matter

• Matter is anything that has

mass and takes up space

• Matter can be classified

based on its physical
properties

• Physical propertiesdescribe

matter

Classifying Matter

Mass

• Matter can be classified by mass

• Mass is how much matter there is in

a substance

• Mass is measured with a balance

LIQUID

GAS

Physical States of Matter

Evaporation

SOLID

COOL

HOT

Condensation

Freezing

• Matter can be classified

based on its physical state:
• Solids
• Liquids
• Gases

• Matter’s physical states can

change by either adding or
releasing energy

Solubility

Solute

Solvent
Solution

• Insoluble = does not dissolve

• Soluble = dissolves

• Cannot see substance

• Adding more water will make

the color lighter

• Heating, stirring, and smaller

particle size will make
dissolving faster

Turn and Talk

Are the oil and sand soluble in water?
How do you know?

Density

• Density is how close together

or crowded particles are

• More crowded or dense than

water = sink

• Less crowded or dense than

water = float

Magnetism

•Magnetism is the pulling force
of a magnet

•Attracted to:

• Iron
• Steel
• Nickel
• Cobalt

Conductivity

•Conductors allow heat or
electricity to pass through

• Copper
• Aluminum
• Gold
• Steel
• Brass

•Insulators do not allow heat or
electricity to pass through

• Foam
• Rubber
• Plastic
• Wood
• Glass

Comparing Mixtures and Solutions

Mixtures

• Two or more substances are

physically combined

• Can be easily separated
• Physical properties are maintained

Solutions

• A special type of mixture in which one

substance is evenly dissolved in
another

• Hard to separate (hot plate)
• Physical properties change

Salt

Sugar

Oil + Water

Sand + Water

Sand and water

Oil and water

Salt and water

Sugar and water

Turn and Talk

Sand, oil, salt, and sugar are added to different
beakers of water and stirred. After stirring and
waiting for 10 minutes, the results are shown.

Where would you place each in this graphic
organizer? Explain your reasoning.

Separating Mixtures

• Mixtures can be separated by their

physical properties:

• Density - sink or float in water

• Magnetism - attracted to iron or

steel (or not)

• Size - separating by size using a

sifter, sieve, or strainer

• Conductivity - conductor or not

• Physical states - separates solids

from liquids (funnels, filters) or
liquids from gases (hot plates)
