Investigation #1- Lighting a Bulb

Q. #1 How did you use the battery to turn on the lightbulb?
A:we used the battery by hooking up one wire on each end of the battery. After that, we figured
out that the end of the battery with the dot has to be touching the bottom of the black part of the lightbulb,
and the flat end of the battery has to touch only the silver

Q. #2 Where did you connect the wires to the battery?
A: we connected the wires to the center of the ends


Q. #3 Where did you connect the wires to the light bulb?
A:we connected the wires to the silver part and the black part


Q. #4 What happens when you touch the wire to the glass part of the bulb?
A:what happens is the bulb gets really hot


Q. #5 What is an Electricity Receiver?
A:it is some electricity

Q. #6 What is a circuit?
A:a circuit is another part of the light bulb



Investigation #2- Let's get this motor running.

Q. #1 What components are needed to make a complete circuit?
A:the motor is needed to make a full circuit


Q. #2 Which part of the circuit was the receiver in this experiment?
A:the motor is the electricity receiver


Q. #3 What is important to remember about making a complete circuit?
A:that you always need some thing electric


Q. #4 How can you get electricity from a battery to the receiver (the motor in this experiment)?
A:there were two wires connecting to the battery


Q. #5 What does a switch do in a circuit?
A:it turns it on and off


Q. #6 What is an open circuit?
A:a circuit that dose not work


Q. #7 What is a closed circuit?
A:a circuit that works


Q. #8 How is the motor circuit like the bulb circuit?
A:they each use electricity


Q. #9 How is it different?
A:a bulb lights up and a motor doesn't



Investigation #3-Are you an insulator or conductor?

1. List the test objects that are conductors and insulators.

2. List the classroom objects that are conductors and insulators.
Conductors
Insulators

















Q. #1 What do you notice is similar about all the conductors?
A:that most of them our metal.

Q. #2 What do you notice about the insulators?
A:that most of them our not metal.

Q. #3 What is a conductor?
A:an object that electricity flows through.

Q. #4 What is an insulator?
A:an object that electricity DOES NOT flow through.
