The diagrams show two trials of an experiment in which a spring scale was used to measure force.
This experiment can be used to determine-
how mass affects the force needed to move objects
how force affects the mass of two objects
how the force used to pull a dictionary affects the mass of a box of marbles
how the mass of a box of marbles affects the mass of a dictionary

In some circuits that are used for decorating, one burned-out lightbulb will prevent all the other lightbulbs from lighting. In other circuits, one burned-out lightbulb will have no effect on the other lightbulbs.
In which of these circuits will the other lightbulbs still light even if one bulb is burned out?
8 Which diagram models the process of compaction leading to the formation of sedimentary rock?
For an investigation a teacher dropped a bolt into a container of maple syrup and asked students to remove it without touching the syrup. The students first tried to use a strong magnet to remove the bolt, but it remained on the bottom of the container. They finally poured the syrup into another container to get the bolt out.
Which of these best describes some of the bolt’s physical properties?
The bolt is magnetic and has the same density as the maple syrup.
The bolt is nonmagnetic and more dense than the maple syrup.
The bolt is nonmagnetic and less dense than the maple syrup.
The bolt is magnetic and less dense than the maple syrup.

Which statement about light is supported by this picture?
Light travels in straight lines until it enters a different material like water in a lake.
Light can refract in air and in clear water.
The water in the lake is blue because light forms an image.
Light is reflected off the smooth surface of the lake.
A material is used to surround electrical wires because it will prevent a person from being shocked. It can also be used to help keep drinks cold for a long time. Which set of physical properties of the material makes it useful for these purposes?
does not conduct electricity, conducts heat
does not conduct electricity, does not conduct heat
conducts electricity, does not conduct heat
conducts electricity, conducts heat
