container into the freezer for 12 hours. What
happens to the juice molecules in the container
during these 12 hours?

Leah is using a 3.4meter (m) ladder to paint the
exterior of her house. Leah has a mass of 50kilograms
(kg). The acceleration due to gravity is equal to 9.8
meters per second squared(m/s²). What force, in
Newton's (N) does Leah exert on the ladder when she is
standing on it?
Calculate the mechanical energy of an object being
thrown through the air. The object has 28 Joules (J) of
potential energy due to its position above the ground,
and 41 Joules (J) of kinetic energy due to its motion.
Mechanical energy = potential energy
If a pendulum is swinging back and forth, energy is
being converted from to another. Kinetic energy is the
energy of motion…so why does the pendulum slow down
and eventually stop if energy is conserved?
Gail’s cross-country coach advised her to eat well-balanced meals in order
to have plenty of energy for their upcoming track meet. To which
transformation of energy is Gail’s coach referring?
A. heat energy to mechanical energy
B. mechanical energy to electrical energy
C. chemical energy to mechanical energy
D. thermodynamic energy to dynamic energy
Explain the changes in potential & kinetic energy as the golf ball moves
through A – D.
Earth / Space
For thousands of years, astronomers believed that all the objects in the
night sky that had produced their own light were individual stars. Since
the invention of the modern telescope, we have been able to examine
those sources of light and have discovered that many of them are not
individual stars. Which sources of light have been found to be collections
of billions of stars and not individual stars?
Carol and Deborah are looking at stars on a dark night and notice that two
stars next to each other are equally bright, but one is red and one is

A. The stars are in different galaxies.
B. The stars are different distances away.
C. The stars are at different stages in their life cycles.
D. The stars have different numbers of planets orbiting them
Although the planets in our solar system have unique features, they also
have similarities. Which of the following characteristics is most similar
among the planets in our solar system?
G. shape of orbit
H. number of satellites
I. chemical composition

b. 4 years
c. 6 years
d. 24 years
a. Earth is in side the galaxy
b. Earth is close to the other galaxy
c. Earth is rotating too quickly to view the galaxy
d. Earth’s atmosphere distorts light from the galaxy
The Milky Way is a spiral galaxy, yet when Gordon looked at the stars one
night, they Milky Way galaxy looked like a flat band of star across the sky.
Why does the Milky Way galaxy appear to be flat?
a. Electric forces are acting on the ball
b. Air resistance is accelerating the ball
c. Magnetic forces are pushing the ball
d. gravitational force is pulling on the ball
Sam drops a rubber ball from the top of a staircase to his friend on the
bottom of the staircase. The speed of the ball increases as it gets farther
away from Sam’s hand.
What is the best explanation for the increase of speed of the ball?
What causes a comet to have a
tail when it nears the Sun?
