Light is a form of energy that you can see.
What is light?

• Column 1, 1

4
In a straight line away from its source in waves.
How does light energy move through space?

• Column 1, 2

5
Transparent means light can go through. Opaque
is the opposite light cannot go through at all.
Translucent means some light goes through.
What is the difference between transparent,
translucent, and opaque?

• Column 1, 3

6
Light reflecting off an object means the light
wave bounces off the object. Refracted light
is when the light waves go through an object and
are bent as it goes through the object.
What is the difference between reflection and
refraction?

• Column 1, 4

7
When light hits a basketball, the ball absorbs,
or takes in all the colors in light except
orange, which is reflected back.
What happens when light is absorbed by an opaque
object like an orange basketball?

• Column 1, 5

8
Solid rocks soils water gases in the
atmosphere
What materials make up the earths features?

• Column 2, 1

9
Natural resources are made by nature and
Man-made resources are made by man.
What is the difference between natural resources
vs. man-made resources?

• Column 2, 2

10
Renewable resources are resources that can be
formed over time. Non-renewable resources are
resources that cannot be formed over time, once
used up, is gone for good.
What is the difference between renewable
resources and non-renewable resources?

• Column 2, 3

11
Natural gas and trees are because they can be
formed over time. Metals and minerals cannot.
Which of the following are renewable resources
natural gas, trees, metals, minerals

• Column 2, 4

12
Recycle develop fuel-efficient cars and homes
use renewable resources walk bike or use the
bus rather than drive the car.
What are some things we can do to help prevent
our resources from becoming used up too fast?

• Column 2, 5

13
Volcanic eruptions, earthquakes, erosion, and
weathering.
The earths surface is being changed constantly.
List 4 ways this occurs. Hint 2 are from
within the earth.

• Column 3, 1

14
Weathering is the breaking or changing of rocks.
Erosion is the moving of weathered rock and soil
by wind, rain, or ice.
What is the difference between weathering and
erosion?

• Column 3, 2

15
Freezing and thawing of water between rocks
trees and plants growing in rock cracks.
What are some ways that weathering takes place?

• Column 3, 3

16
It helps to form new soil, build new land but at
the same time it is taking away soil and land
from other areas such as farms, roads.
How is something like weathering and erosion
helpful to people like farmers and at the same
time be hurtful?

• Column 3, 4

17
Plant trees on steep hills in bare areas plant
grasses and other ground coverings because they
will absorb rainwater and its roots will hold the
soil down.
What are some ways people can prevent erosion?

• Column 3, 5

18
It is where the object is located compared to
where others are. Example the chair is to my
left.
What do we mean by the relative position of an
object? Give an example.

• Column 4, 1

19
It is a push or a pull on an object that can
cause it to change its motion.
What is a force?

• Column 4, 2

20

• Friction can slow down an object
• Gravity pulls 2 objects towards each other.

What are 2 forces that can affect the motion of
an object? List them and tell what they do.

• Column 4, 3

21
Sound is a kind of energy you can hear. It is
matter vibrating, or moving quickly back and
forth.
What is sound and how is sound made?

• Column 4, 4

22
Volume is how loud or soft a sound is shouting
vs. whispering. Pitch is about how high or low
a sound is high screech of a train whistle vs.
low sound of a kettle drum.
Volume and pitch are properties of sound. What
is volume and what is pitch? Give an example.

• Column 4, 5

23
Anything that has mass and takes up space.
What is matter?

• Column 5, 1

24
Mass is the amount of material an object has in
it. Volume is the amount of space that matter
takes up.
What is mass? What is volume

• Column 5, 2

25
color, shape, size, and mass.
What are the 4 physical properties we use to
describe matter?

• Column 5, 3

26
Solid, liquid, or gas.

• Matter can be found in one of 3 states or forms.
• What are these states of matter?

• Column 5, 4

27
No. Solids have a shape and volume of its own.
Liquids have volume but take the shape of
whatever container it is in. Gases have neither
shape nor volume of its own

• Do the 3 states of matter have a specific shape
  of its own and/or volume?
• If not what does each have?

• Column 5, 5
