Mixtures and

SolutionsEnergy

Anything that takes up space is what?

Bonus: How do you measure the amount of space something takes up?

Matter

100

An object’s _________ will differ depending on where it is in the universe.

A) MassB) WeightC) DensityD) Volume

WeightFact: An object’s weight depends on the gravitational pull of the earth. An object weights 6 times more on

earth than it does in space (due to gravity).

200

Which tool would be used to measure the mass of a battery?

A) B)

C) D)

a Balance

300

Which liquid has a greater density?

Liquid A

Liquid B

Liquid C

Liquid C

400

Why? Because the matter is packed tighter together in Liquid C causing it to settle at the bottom

A beaker would most likely be used to find the __________ of a liquid.

Hint: What measurement of matter?

Volume

Fact: Volume determines the amount of space an object takes up. We could measure how much space the liquid takes up in milliliters.

500

Identify each state of matter in relation to the number of

molecules in each?

A)

C)

B)

100

A)

C)

B)

Liquid

Solid

Gas

What is the point at which a liquid changes

to a solid

Freezing Point

Bonus: What is the point at which a solid changes to a liquid?

200

Which of the following is an example of a chemical change?

A B

C D

SaltSugar

A

The fire is a chemical change because it produces something

new – a gas300300

An ice cube was put on a scale and weighed 3 ounces. One

hour later the ice cube melted. How much will the melted ice

weight?

The ice should weight the same (or a little less due to

evaporation) because the only thing that happened was a

physical change.

Water Vegetable Oil Vinegar

If the temperature of vegetable oil reached 400 degrees what state of

matter would it be in?

Gas

Why? Because once the substance reaches the boiling point it changes phases of matter (from a liquid to a

gas)

500

What is two or more substances that have

not combined chemically called?

Mixture

Bonus: Give an example of a mixture?

100

Because sugar dissolves in water what is Kool-Aid an example

of?

Solution

200

Is salt or pepper more soluble in water based on the pictures below:

Salt and Water Pepper and Water

Salt because it mixes more thoroughly in the

water.

300300

What steps could you do to separate a mixture of salt, water, and rocks?

1. Evaporate the water out of the mixture (sun or heat)2. Pick the rocks out of the mixture.3. Leave the salt with all three substances separated. 400

Which process would result in the forming of a solution?

A) EvaporationB) MeltingC) FreezingD) Dissolving

D) Dissolving – because if a substance

dissolves in another substance it creates a solution

(such as sugar and water).

500

What type of energy is stored energy that can

be released later?

Potential Energy

100

What types of energy can electricity convert to?

Heat, Sound, and LightAlso motion

200

If each light bulb is NOT hooked up to the energy source what type of

circuit is it called:

A)Series circuit

B)Parallel circuit

C)Magnetic circuit

D)Copper circuit

Series Circuit

300300

This prism is an example of light doing what?

A) Reflecting

B) Refracting

C) Sliding

D) Flipping

B) Refractingbecause the light is bending as it

passes through the object

400

When the student bangs When the student bangs the drum what makes the the drum what makes the

sound?sound?

Vibrations

500

Which is the correct order to show how energy flows through this

community?

C)

B)

A)

100

C)

The primary source of energy is the sun. The sun gives energy to the plants to make photosynthesis and herbivores eat the plants while carnivores eat the herbivores.

This tool is used to measure what

Temperature

200

This is the statement that states what you “think” will happen.Educated Guess.

Hypothesis

300

A B

Which plant would most likely live in a cool, dry climate?

Why?

ABecause the thin dry leaves

(needles) can survive the coldBonus: What type of tree is this called?

(300 points)

400

Which of the following best helps an owl survive in a cold climate?

A.Nocturnal Eyes

B.Pointed Beak

C.Camouflage

D.Thick Fur

Thick Fur(for cold climates)
