Students drop the same heavy ball onto identical blocks of soft clay from different heights. For each height they measure the depth of the dent the ball makes in the clay. Why is the depth of the dent different in each trial?
The size of the ball changes
The material of the ball changes
The mass of the ball when it hits the clay changes
The force of the ball when it hits the clay changes
Which of these is not soluble in water?
Oil
Salt
Honey
Sugar
A student uses a set of headphones to listen to music. Which of these objects uses the same source of energy as the headphones?
A flute using wind energy
A piano using mechanical energy
A keyboard using electrical energy
A teapot using thermal energy
Many people ride a bicycle for fun and exercise. Some people ride a bicycle to work because it saves money and benefits the environment by reducing the use of fossil fuels. Which of these is NOT an example of the bicycle using mechanical energy?
The pedals, gears, and chain help turn the wheels.
The wheels turn when the bicycle moves.
The front wheel guides the bicycle as it moves.
The reflector allows the bicycle to be seen at night.
A group of students built the circuit shown. The lightbulb does not glow. Which statement explains this observation?
The battery is not charged.
The lightbulb is not part of a complete circuit.
The circuit does not have a switch.
The bell uses most of the energy from the battery.
Some students investigate the properties of four objects using a hand lens, a magnet, and a beaker containing water. Their observations are recorded in the table. Which statement identifies a property that could be used to classify these objects into two different groups?
Density can be used to separate objects that sink in water from objects that do not.
Magnetism can be used to separate objects that are attracted by a magnet from objects that are not.
Solubility can be used to separate objects that dissolve in water from objects that do not.
Physical state can be used to separate objects that are solids from objects that are not.
A student observed liquid wax dripping down the side of a burning candle. After putting out the candle’s flame, the student left the room. Several hours later the student observed that there was no longer any liquid on the side of the candle. Which statement explains what most likely happened to the liquid wax?
The heat given off by the flame caused the candle wax to evaporate.
The liquid wax changed back into a solid as it cooled.
The liquid wax condensed and was absorbed by the candle.
None of the above
