5th - Science Unit 1 Lesson 2

Question 0

What are some examples of chemical properties?

Answer 0

Flammability, corrosion, photosynthesis. Anything that describes the way a substance reacts to other substances (more or less reactive)

Question 1

What are some examples of physical properties?

Answer 1

Mass, weight, volume, conduction, magnetism, light transmission, density, color. Anything you can observe about on object.

Question 2

What are some examples of qualitative properties?

Answer 2

Color, odor, state (solid, gas, liquid), texture, luster, and malleability

Question 3

What are some examples of quantitative properties?

Answer 3

Mass, melting point, boiling point

Question 4

Know the difference between mass, weight, and volume.

Answer 4

Mass is the amount of matter in an object. Weight is how strongly gravity pulls on an object. Volume measures how much space matter takes up.

Question 5

Be able to explain why the weight of an object will be different on a planet with different gravitational pull.

Answer 5

Weight is how strongly gravity pulls on an object. If an object has more mass, it will also have more weight. Gravity is greater on planets with more mass, so an object’s weight depends on the planet it is on. An object’s mass, in contrast, is the same on different planets.

Question 6

What is used to measure mass, weight, and volume?

Answer 6

Mass is measured on an equal pan balance. Weight is measured on a scale. Volume is measured by multiplying the object’s length by its width by its height.

Question 7

What units is mass, weight, and volume usually given in?

Answer 7

Mass is usually given in kilograms or grams. Weight is usually given in newtons or pounds. Volume is usually given in milliliters or cubic centimeters.

Question 8

How do you find the volume of a regularly shaped solid?

Answer 8

You can calculate the volume of a regularly shaped object such as a rectangular solid by multiply the object’s length (L) by its width (W) by its height (H): L x W x H.

Question 9

How do you find the volume of an irregularly shaped solid?

Answer 9

You can measure the volume of an irregular shaped solid by using water in a graduated cylinder or beaker. The change in the water level when an irregular object is placed under water.

Question 10

What is the formula to calculate density?

Answer 10

To calculate density, you divide its mass by is volume.

Density = mass / volume

Question 11

Which property describes why an object floats?

Answer 11

Objects can float as a result of buoyancy, it’s resistance to sinking.

Question 12

Know when an object will float in water and when an object will sink in water.

Answer 12

If an object is denser than the liquid, then the object can push harder and it sinks. If the liquid is denser than the object, then the liquid can push harder and the object floats.

Question 13

What is the movement of light through a substance such as air or water?

Answer 13

Light transmission

Question 14

What is it called when an object or substances allows most light to pass through? Examples are air, glass and water.

Answer 14

Transparent

Question 15

What are objects or substances called that blur light as it passes through? Examples are waxed paper, ice, and frosted glass.

Answer 15

Translucent

Question 16

What are objects or substances called that allows little or no light to pass through? Examples are wood, rubber and metal.

Answer 16

Opaque

Question 17

What is conduction?

Answer 17

Conduction is the passing of heat through a material while the material itself stays in place. It occurs between objects that are touching. When touching a seat belt on a hot day, the metal buckle feels hotter than the cloth strap.

Question 18

If given a picture of an object in a graduated cylinder, be able to tell its volume.

Answer 18

Question 19

What is the difference between an alkali metal and an alkaline earth metal?

Answer 19

Alkali metals easily form compounds with other substances and never exist by themselves in nature. Alkaline earth metals are not as reactive as alkali metals and are essential to many living organisms.

Question 20

Be able to explain why the temperature at which a substance boils or freezes is classified as a physical property and not a chemical property.

Answer 20

Because that is when a substances changes form

Question 21

Matter can be described by its ______________ and its ___________________ which are physical properties.

Answer 21

Color and texture

Question 22

What is used to identify matter without changing its identity?

Answer 22

Physical properties

Question 23

What is the amount of matter in an object?

Answer 23

Mass

Question 24

What changes as the force of gravity changes?

Answer 24

Weight

Question 25

What is the amount of space that an object takes up?

Answer 25

Volume

Question 26

What is the amount of matter per milliliter of a substance?

Answer 26

Density

Question 27

What is the ability to transfer heat?

Answer 27

Conduction

Question 28

What describes the way that matter reacts with other substances?

Answer 28

Chemical properties

Question 29

What describes a substance that catches fire easily ?

Answer 29

Flammability

Question 30

What are the two ways that properties of matter can be classified?

Answer 30

Extensive and intensive
