Ariana uses balloons to investigate static electricity. Which of the following best explains what will happen when she brings two positively charged balloons close to each other?
the balloons will move apart
one balloon will lose its charge
the balloons will come together
one balloon will gain a negative charge
A radiometer is a device with fins that spin when light energy strikes them. A picture of a radiometer is shown below. As part of an experiment, a light source was placed 50 centimeters (cm) from a radiometer. The light source gave off four different colored lights for 30 seconds each. After each color of light was turned off, the amount of time the fins on the radiometer spun was recorded. The results are shown in the table.
Which color of light was provided the greatest amount of light energy according to the data in the table?
red
blue
green
white
Jason stretches a rubber band between his fingers, as shown. When he plucks the rubber band, it makes a sound.
Which of the following best explains why the rubber band makes a sound when Jason plucks it?
it heats the air
it vibrates the air
it absorbs energy from the air
it releases molecules into the air
Frank uses a bowling ball to demonstrate how energy can cause changes. Which of the following actions would NOT demonstrate a change caused by applying energy to the ball.
he holds the bowling ball in both hands
he spins the bowling ball with one hand
he rolls the bowling ball across the floor
he lifts the bowling ball to place it on a shelf
Electric circuits must be properly connected or electricity will not flow. Which of the follow shows a properly connected circuit that would allow electricity to flow and light the bulb?
Upper left corner
Upper right corner
Lower left corner
Lower right corner
Tanisha built the circuit in the picture using a battery, insulated copper wire, and an iron nail. The iron nail has become magnetized by the battery and is attracting a metal paper clip.
Which form of energy caused this nail to become magnetized?
mechanical

light
electrical
Light waves change speed as they travel from the Sun to Earth's surface. Which of the following causes most of this change in the speed of light waves?
Earth's shape
Earth's gravity
Earth's atmosphere
Earth's mountains
To make a dull coin shiny, Luca polished the coin by rubbing it with a soft cloth. When he was finished, he noticed the coin felt warmer than before he polished it. Which of the following best explains why the coin felt warmer?
the sun is only one of the many things to give off light
heat is produced when one object rubs another
light is produced when one object rubs another
some objects store more chemical energy that is given off as heat
When Maria plugs in and turns on her new alarm clock, the alarm sounds ringing. Which energy transformation takes place?
electrical energy changes to solar energy
chemical energy changes to sound energy
electrical energy changes to sound energy
sound energy changes to mechanical energy
How objects appear depends on the different ways in which light acts. The picture shows a straw in a glass of fruit juice.
Which of the following explains why the straw appears the way it down in the picture?
light bounces back as it strikes a surface
more light is taken in by dull substances than by shiny ones
light changes to heat when it is taken in by new substances
light bends as it passes from one substance to another
For a special dinner, Catherine's mom lit some candles in the living room for decoration.
What are two forms of energy that the fire from a burning candle releases?
light and heat
sound and chemical
magnetic and nuclear
electrical and mechanical
Thomas followed these steps in an investigation:
1. Collect the materials to build two identical electrical circuits, one with aluminum wire and one with plastic cord.
2. Use aluminum wire as the connection to build one closed circuit.
3. Use plastic cord as the connection to build a second closed circuit.
4. Record your observations.
Which of the following statements is Thomas most likely testing?
all nonmetals are poor conductors of electricity
all types of metal are good conductors of electricity
aluminum is a better conductor of electricity than plastic
closed circuits allow electricity to flow better than open circuits do
Mechanical energy is one of many forms of energy. Which of the following is an example of mechanical energy?
energy from a radio
the energy that runs a refrigerator
the energy that comes from a lightbulb
the energy of a moving wagon

heat moves from the milk to the bowl
heat moves from the bowl to the milk
heat does not move between the bowl and the milk
heat moves both ways between the milk and the bowl
A balloon sticks to a chair after the balloon is rubbed with a cloth. Which of the following best explains why the balloon sticks to the chair?
like charges attract each other
neither of the objects has a charge
opposite charges attract each other
both objects have a positive charge
Jada is showing her classmates how light sometimes travels. On the board, she draws the picture:
Which of the following is Jada most likely showing her classmates?
how light is bent as it passes from air to an object
how light bounces off an object when it is reflected
how light moves when it does not encounter an object
how light is absorbed as it passes from air to an object
