(b) baking cookies in an oven
(c) using gasoline to run an engine
A1

(c) using gasoline to run an
engine
Q2

Which type of energy is due to
the movement of electrons?
A2

Electrical Energy
Q3

What could you do to decrease
the thermal energy of an
object?
A3

Cool it
Q4

What is an experiment you
could do to show that plants
need light to grow?
A4

Example: grow plants in light
and plants without light and
compare how they grow
Q5

What natural source of energy
would cause a swimming pool
to warm up in the daytime?
A5

Solar Energy
Q6

If a thermometer is placed in a
glass of ice water, how will the
thermal energy be effected?
A6

A decrease in thermal energy,
causing the liquid to contract.
Q7

When you push a spring
together, before releasing it,
what type of energy do you
have? Kinetic or potential?
A7

Potential Energy
Q8

Which of the following can only
be seen because of light
reflecting off of it from a source
other than itself?
A) sun          B) lightning
C) flashlight   D) cloud
A8

D) cloud
Q9

A thermometer measures
which kind of energy?
A9

Thermal Energy
Q10

What conditions are best for a
solar cooker to heat food?
A10

When a solar cooker is placed
outside in a sunny location,
Q11

When a balloon is rubbed on a
wool cloth, it will receive a
negative charge. What
happens when this balloon is
placed near a wall and why?
A11

The balloon sticks to the wall
because the negative charged
object is attracted to an object
with no charge.
Q12

Which energy transformation
happens when a fan is plugged
into a wall and turned on?
A12

Electrical energy into energy of
motion
Q13

What is the dependent variable in
the following scientific question?
 What is the effect of the amount of
times (5 or 20) a balloon is rubbed on a
piece of wool, on the number of cereal
pieces the balloon will pick up?
A13

The number of cereal pieces the
balloon picks up.
Q14

What is the independent variable
in the following scientific
question?
 What is the effect of the amount of
times (5 or 20) a balloon is rubbed on a
piece of wool, on the number of cereal
pieces the balloon will pick up?
A14

The number of rubs (5 or 20) on
the piece of wool.
Q15

What are 3 predictions for this
experiment?
 What is the effect of the amount of
times (5 or 20) a balloon is rubbed on a
piece of wool, on the number of cereal
pieces the balloon will pick up?
A15

1. The balloon with 5 rubs on the
wool will pick up more cereal.
2. The balloon with 20 rubs on the
wool will pick up more cereal.
3. The balloon with 5 rubs will pick
up the same number of cereal
pieces as the balloon with 20 rubs.
