A foam dart is thrown toward a dartboard. The graph represents
its motion. At about what speed is the dart traveling when it
hits the dartboard, 7 meters from the starting point?

The question says the
target is 7 meters from the
starting point. You have to
predict where the line
would be at 7 meters.
11

→ ecosystem
D. grass → robin → mushroom → bear
16
C.
consumer → food chain → food web → ecosystem
Because it is organized from least to most complex
17

A woman is suddenly awakened by the
smell of smoke and fire coming from the
next room. She flees from the burning
building. This situation illustrates the
interaction of the –
A. Digestive and circulatory systems
B. Respiratory and circulatory systems
C. Endocrine and integumentary systems
D. Nervous and muscular systems
20
D. Nervous and muscular systems
The sense of smell from the nervous
system helped detect smoke, and
muscles helped her run out of the
house.
21
Which of the following is an
example of a chemical property?
A Density
B Shape
C Color
D Flammability
22
D. Flammability
Density, Color, and Shape
are Physical properties
23
The equation above shows the chemical reaction
for burning coal. Which of the following best
explains the reaction represented by this equation?
A Carbon dioxide gas breaks down into solid
carbon and oxygen gas.
B Solid carbon reacts with oxygen gas to produce
carbon dioxide gas.
C Solid carbon, oxygen gas, and carbon dioxide
gas react to form products.
D Oxygen gas heats solid carbon, melting the
carbon into a liquid.
24
B. Solid carbon reacts with
oxygen gas to produce carbon
dioxide gas.
25
Which of the following is an example
of a chemical reaction?
A. A magnet separates iron filings from
sand.
B. A kettle boils water.
C. A candle burns on a birthday cake.
D. A spoonful of sugar dissolves in
water.
26
C. A candle burns on a birthday
cake.
Anything burning produces
smoke which is a new substance.
It is evidence of a chemical
change.
27
Based on the periodic table, which of
the following elements has
properties most like neon’s?
A Hydrogen (H)
B Fluorine (F)
C Krypton (Kr)
D Sodium (Na)
28
C. Krypton (Kr)
Krypton and Neon are both in the
same column on the periodic
table. This indicates they have
similar properties.
29
Which letter in this model of a boron atom
represents a proton?
A. W
B. X
C. Y
D. Z
30
C. Y
Protons have a positive
charge and are found in the
nucleus of an atom.
31
Diesel fuel is used in the engines of the
machines and trucks. Which of these is the main
energy transformation as the fuel is used by the
engines?
A. Electrical energy is converted to heat energy.
B. Heat energy is converted to potential energy.
C. Electrical energy is converted to kinetic energy.
D. Chemical energy is converted to kinetic energy.
32
D. Chemical energy is converted to
kinetic energy.
Fuel holds chemical energy, and it allows
the truck to move (kinetic).
33
Iron has a higher specific heat than silver. If 1 g
of each metal is heated equally and placed into
equal amounts of tap water, what will happen?
A. Neither metal will cause a change in the
water’s temperature.
B. The silver will cause a greater change in
the water’s temperature.
C. Both metals will cause the same change
in the water’s temperature.
D. The iron will cause a greater change in
the water’s temperature.
34
B. The silver will cause a greater
change in the water’s temperature.
The silver has lower specific heat so
it will more easily transfer heat to
the water.
35
Which of the following is not an
example of kinetic energy being
converted into potential energy?
A. A basketball player jumping for
a rebound.
B. Releasing a compressed spring.
C. Pulling a sled uphill.

hour
38
B. 15 kilometers per hour
Average speed = distance / time
In the graph, follow the line. Divide
the distance by time and you will get
15km/hr.
39

the Earth _________.
A. a large amount of light
B. the same amount of light as in Phase Y
C. a crescent shape of light

star  planet
C. planet  star  solar system  galaxy
 universe
D. universe  planet  solar system 
