Electricity SP52

What needs to be added to complete the simple electric circuit?

• 1. The simple circuit needs a power source such as a battery to be complete and light the light bulb.

•  The simple circuit needs a switch because a circuit needs to have a switch to be able to be turned on and off.

•  The simple circuit needs a rubber band to connect the wires because the wires are coated with rubber or plastic.

• 1. The simple circuit needs a piece of copper to connect the wires because the circuit needs a    conductor to continue the flow of current.

Which is one way static electricity is different than current electricity?

• 1. Static electricity is constantly moving. 

• 1. Static electricity is created in power plants. 

• 1. Static electricity usually cannot be controlled.

• 1. Static electricity causes a shock when touched. 

Mrs. Hargrave’s class was completing a science experiment. One student had a balloon that had a negative electric charge. Another student held up a piece of cloth to the balloon. The cloth was attracted to the balloon.

Which explains how this type of electrical charge differs from the charge that comes from a battery?

• 1. The charge on the balloon will not last for a long time.

• 1. The charge on the balloon will not give you a shock.

• 1. The charge on the balloon cannot produce light.

• 1. The charge on the balloon cannot start a fire.

Which component is missing for a complete electric circuit?

• Switch

• Conductor

• Power Source

• Object using the current

Percy built a simple circuit to test different insulators and conductors.

What will MOST LIKELY happen if Percy replaced the metal paper clip with a plastic paper clip?

• 1. The plastic paper clip will act as a conductor, and the light will turn on.

• 1. The plastic paper clip will conduct electricity, but the light will not turn on.

• 1. The plastic paper clip will not conduct electricity, but the light will turn on.

• 1. The plastic paper clip will act as an insulator, and the light will not turn on.

Which explains how you could build a complete circuit without using each of these items?

• 1. Attach the lamp directly to the positive end of the cell since it provides the power.

• 1. Use two pieces of cable to connect the lamp to the switch since it controls the power.

• 1. Attach the lamp to one end of the cell using one piece of wire since it conducts electricity.

• 1. Use two pieces of cable to attach the lamp to both ends of the cell since it provides the power.

Both static and current electricity can produce light.

Which statement BEST explains how static and current electricity differ in their ability to produce light?

• 1. Static electricity produces more light.

• 1. Light from static electricity travels faster.  

• 1. Current electricity can produce light for a longer time. 

• 1. You cannot choose where light from current electricity appears. 

Julian is completing an investigation on how electricity flows.  He began his investigation by placing a penny in an electrical circuit, and the light lit up.  

He replaced the penny with the other listed items and recorded his results.

Based on his results, which item will conduct electricity and cause the light to stay lit?

• 1. a letter made of wood

• 1. a rubber ball

• 1. a metal hair clip

• 1. a plastic building block

Manny's sister created this simple circuit, but she cannot make the light bulb light up. 

  

What should Manny do to help his sister fix her simple circuit?

• 1. Manny should replace the battery because the power source is not working in the circuit.

• 1. Manny should close the switch area that is open, so all of the parts of the circuit are completed.

• 1. Manny should place a piece of wood in the open switch to change the direction of the flow of electricity in the circuit.

• 1. Manny should move the power source to the open area where the switch should be so that the power source is closer to the light bulb.

Carly built a simple circuit for science class.

Which BEST explains what will happen when Carly presses the switch into the “on” position?

• The light bulb will not turn on because the wire is not attached to both ends of the power cell.

• The light bulb will turn on because the switch will close the circuit and allow the electricity to flow.

• The light bulb will not turn on because Carly attached the switch in front of the bulb instead of behind.

• The light bulb will turn on because the wire is attached to all components of the circuit with no gaps.
