 Reviewed the scribe posts- lables
learned how to do the scribe labels

What material can electrical energy flow through- experiment



A. Materials needed for the experiment: Alligator wires,

B. Setup for the experiment:



  1. Connect objects to the alligator clips wire.  
  2. Touch those objects to the terminal of the battery that does not have alligator wire attached.
  3. Record your observations as conducts if the needle moves.  Record your observation as insulates if the needle does not move.  Record the reading on the ammeter.
  4. Repeat steps 1 to 3 for all the objects.




    When we were all setup for the experiment, we started to test the materials; how much electric energy did the material flow. We tested all the materials and measured their potency.
    In this image you can see my partner measuring the potency of one of the materials. The ammeter is the object seen in the image, it measures the energy. The difference between the materials are that each one sends a part of the battery's electric energy.

These are the investigations that we recorded while testing the materials: 


Material
Conducts or Insulates
Reading on the Ammeter / A
Qualitative (describe observations using words and NOT numbers)
pen
I
0
It does not conduct energy.
pencil
C ( the metal part)
2.9
the metal part of the pencil does conduct energy
motor
C
0.1 or 1.1
If you hold the spinning thing it makes more energy
pyrite
C
0.1
It has metal
graphite
C
1.7
It has lots of metal
Obsidian
I
0

bar magnet
C
3.1
It is a really strong conductor
wire with copper exposed
C
3.0
Cooper is a really strong conductor thats why it has a big electricity absorbed
wire completely insulated
I/C
0.0
If the metal touches the wire it still will send electrical charge
rubber hose
I
0.0
Nothing happens
rusty nail
C
3.0
rust conducts more electricity
paper clip
C
3.0
it conducts because it is made from metal


Insulator: Object that does not carry
 electric energy though it.
Conductors: Object that can carry and transport electric energy.

  2. Include instructions and an example on how to read the ammeter. Also include how to do scribe labels.
