Students attached a buzzer to a battery with a switch. The busser is not making any noise. Which of the following changes would most likely make the buzzer produce sound?

All of the objects below are conductors of electricity EXCEPT-

Students hooked up a battery and bulb with wires as shown. For the bulb to light, the object the students place in the space between the two wires must be-

Elijah places four different materials at the same temperature onto a hot plate to find out which material is the best insulator. The information presented in the table shows the temperature of each material after 15 minutes. Elijah can conclude that which of the following materials is the best insulator?

The illustration shows a circuit with a battery, a bulb, and an open switch, all connected with wires. This electric circuit can be completed by-

Conductors allow thermal and electrical energy to pass through easily. Insulators prevent the flow of thermal and electrical energy. Which of the following items is a poor conductor and a good insulator?

A material that allows energy to easily flow through it

A closed path that an electric current can move along

The flow of charged particles along a path

A material that blocks the flow of energy

Which of the following is a question about forces that could be explored in a laboratory investigation?

Students are exploring how the size of a marble affects the distance it rolls. What tool will they need?

Students are investigating the effect of different surfaces (tile, wood, and carpet) on the time it takes a toy car two meters. The students are measuring the effect of which of the following forces?

Students collected this data in an investigation. Which question would the students be able to answer with this data?

Students performed an investigation in which they tied three washers to different lengths of string.  They hung the washers to swing back and forth one time.  Their data supports which of the following conclusions?  The time to swing back and forth  increases with-

By changing the surface over which a ball rolls, students could investigate the effect of which of the following?

Which two tools below would be most useful in investigating how the mass of an object can affect the distance it moves with a push?

Which of the following describes the best way to investigate the strength of several different magnets?

Students conducted an investigation in which they rolled marbles across different surfaces to measure the force of friction on each surface.  Friction slows down and stops objects.  Which of the surfaces investigated showed the greatest amount of friction?

A push or pull is called?

A force created when objects rub together; works to slow and stop motion is called

A force that can push apart or pull together two objects of iron or steel-

A force that pulls objects together, like a cup to the floor or Earth in its orbit-
