Milestones Practice: Electricity

A student is constructing four different electrical circuits. Each circuit has a battery, wires, a switch, and a light bulb. Which of the following is the best way for the student to record information so that another student can construct exactly the same four circuits?

• Draw a diagram that shows each circuit

• Make a tally of the parts used in each circuit

• Make a list of the materials needed for each circuit

• Create a graph that shows the number of parts in each circuit

A student in science class made this circuit, but the bulb did not light. What did the teacher explain he should have done to make the bulb light?

• Use a second switch

• Use a power source

• Make both of the wires longer

• connect the bulb to only one wire

Lily and Bessma are studying electricity in their science class. They want to make a table that compares static electricity to current electricity. The table is shown below, but it is not yet complete.

Which of the following would be best to replace the X in the table?

• A flashlight is turned on using a switch

• A lightning strike during a storm

• A battery-powered toy robot starts to move

• A computer cord is plugged into an outlet

Landon has a circuit that uses a battery to light up a light bulb. He needs three wires to make his circuit. He changes the circuit to have a paper clip attached to wire 2 as shown in the picture.

What should Landon predict will happen when he connects wire 3 to the paper clip?

• The paper clip will turn black

• The battery will die

• The light bulb will light up

• The light bulb will break

Vacuum cords are coated with rubber or plastic to protect people from the electricity that runs through the cord.

Why is this?

• Rubber is an electric conductor

• Rubber is an electric insulator

• Rubber is easy to handle

• Rubber looks pretty

Which of the following objects would be the best conductor of electricity?

• A piece of paper

• A peanut

• A basketball

• A staple

The image shows a device that can be used to test whether an object is an electrical conductor.

Which of the following describes the best method of using the device to test whether a particular object is an electrical conductor?

• Remove the batteries, and place the object in the battery case

• Disconnect the light bulb, and connect the object to one of the two wires where the light bulb was

• Touch the object to only one of the metal terminals

• Touch the object to both metal terminals at the same time

Students conducted an investigation with balloons and made the notes shown. What can explain the movement of the balloons?

• Gravitational pull

• magnetic attraction

• current electricity

• static electricity

The diagram below shows an incomplete circuit. Which action, using Wire Z completes the circuit so the buzzer will sound?

• Connect 1 to the positive end of the battery; connect 2 to the bottom of the buzzer

• Connect 1 to the positive end of the battery; connect 2 to the negative side of the battery

• Connect 1 to the negative end of the battery; connect 2 to the bottom of the buzzer

• Connect 1 to the top of the buzzer; connect 2 to the bottom of the buzzer

Brandon is doing a science project to find out what materials complete the circuit shown to make the bell ring. He closed the circuit with a plastic pen cap and then a wooden craft stick.

Why did the bell not ring?

• The plastic and wood are insulators

• The plastic and the wood have too much power

• The plastic and the wood were wet

• The plastic and the wood are conductors
