Multiple Choice

A change that only affects the appearance of a substance (its size, shape, or state of matter)

• physical change

• chemical change

Multiple Choice

a change in which one kind of matter changes into a different kind of matter with different properties

• chemical change

• physical change

Multiple Choice

What is a property?

• Stuff that describes stuff
• All matter
• Characteristic of matter
• Only how something looks

Multiple Choice

Which of the following is a sign that a chemical reaction has occurred?

• change in shape
• melting
• formation of a gas
• dissolving

Multiple Choice

• chemical change
• physical change
• chemical reaction
• electron change

Multiple Choice

Which of the following is NOT an example of a physical change?

• crumpled paper

• pencil sharpening

• shrunken clothing

• sour milk

Multiple Choice

Kim puts an ice cube in a beaker and it melts. This is a good example of:

• a physical change.

• a chemical change.

• an experiment.

• an analysis.

Multiple Choice

Marie had a beaker with a small amount of baking soda. She added a few drops of pickle juice to the baking soda and observed fizzing and bubbling. Based on her observation, which of these can Marie determine about the new substance formed by mixing the baking soda and pickle juice?

• A chemical reaction produced a solid.
• A chemical reaction produced a gas.
• No chemical reaction took place.
• Only a physical change happened.

Multiple Choice

Which of the following is an example that includes evidence of a chemical reaction?

• A sample of zinc is placed in water and it settles to the bottom
• A solid block of ice is heated and it completely melts into a liquid. 
• Sugar that is burned gives off an odor and turns brown and then black.
• A tomato is placed into a blender and chopped up into smaller pieces.

Multiple Choice

Which is NOT an indication of a chemical change?

• temperature change

• formation of a precipitate

• shape change

• production of light

Multiple Choice

Which of the following is a physical property of matter? 

• Flammability

• Reactivity

• Solubility

• Combustability 

Multiple Choice

Density - Physical or chemical property?

• Physical

• Chemical

Multiple Choice

How are physical and chemical properties different?

• Chemical properties only apply to chemicals. Physical properties apply to everything.

• Chemical properties are only observable as the substance is changing. Physical properties are easily observed or measured.

• Chemical properties are easy to reverse, and physical properties cannot be reversed. 

Multiple Choice

Mass - Physical or chemical property?

• Physical

• Chemical

Multiple Choice

Flammability - Physical or chemical property?

• Physical

• Chemical

Multiple Choice

Melting Point- Physical or chemical property?

solvent

solute

Multiple Choice

Which statement is true?

• Oil is the most dense substance.

• Corn syrup is less dense than water.

• Oil is less dense than water.

• Oil and corn syrup have the same density but different masses.

Multiple Choice

Matter is anything that has _______ and takes up space. 

• weight

• mass 

• the ability to float

Multiple Choice

Sand in water.

• Solution

• Suspension

• Colloid

Multiple Choice

Why are these particles "suspended" at the top of the water in this jar?

• They are heavy so they float

• They are more dense than water so they go to the top

• They are less dense than water so they are suspended

• They contain sugar so they are black.

Multiple Choice

• DRY MIX

• HOT DOG

• SUB WAY

• NOT ALL

H. DATA - Qualitative vs. Quantitative

DATA – QUALITATIVE AND QUANTITATIVE

QUANTITIATIVE DATA – Numerical (QUANTITY)

• Can be GRAPHED
• If you COUNT or MEASURE, you are collecting QUANTITATIVE DATA

QUALITATIVE DATA – Descriptive (QUALITY)

• OBSERVATIONS, and uses WORDS
• Example: THE COLOR OF A FLOWER, THE SMELL OF PERFUME, THE

TEXTURE OF A ROCK
