Can You Tell if it is "Conducts" or "Insulates"? - Reading the Ammeter

Expert Collaboration by Ivanna Hidalgo


 Block 1 - August 27th
What we did in class today was reviewing the scribe roll, answering the energy questions, expert collaboration survey, and ?Investigate what materials can electricity flow through.

Scribe Roll
What we did in the scribe roll was deciding who and when the rest of the students went. Next is Mary, and if you want to view every ones date, go to the Science Office.
Energy Questions & Answers
This suppose Q & A is about questions that are asked and related about energy. These questions are related to the test and a sort of study guide. Unfortunately, I couldn't take a picture of the screen but there sure is the form in the Science Office.
Expert Collaboration
The expert collaboration is a survey that Mr. Prophet sent us with a few questions on it. Each group (wind, geothermal, hydroelectric, nuclear, and solar) had to answer a question according to their topic. To know everything about their topic, they had specific textbooks and textbook pages to read. For example, Tobin tried to read all of the pages that were given for the geothermal and his group answered the question accurately.


This is one of the pages that were included in the Geothermal section. According to Tobin's opinion, it was really helpful to read the pages, so he know how to answer the questions quicker.

Here, I have the Geothermal group filling out their survey. As I saw them, they had almost no difficulty filling it out. I moved to other groups and some were more focused than others.


Investigate What Materials Can Electricity Flow Through (Key)
We went through the answers in class and almost every one got an accurate answer. The results are here...

Material
Conducts (C) or Insulates (I)
Reading on the Ammeter
/ A
Qualitative (describe observations using words and NOT numbers)
pen
I
0
plastic
pencil
I
0
wood
motor
C
0.1
- the motor spun,
- if the motor spinning was held, the reading on the ammeter increased!
- a humming sound
pyrite
C
0.4
the more the alligator clip was pushed on the pyrite, the more the current was
graphite
C
3+, 1.8
the needle moved a lot
quartz
I
0
white rock
aluminum bar
C
3+
the terminals heat up a little
wire with copper exposed
C
3+
the terminals heat up a little
wire completely insulated
I
0
- if the clips are touched to the little bit of wire inside the insulation and the wire is touched to the terminal, it will read a current
rubber hose
I
0
- rubber
rusty nail
C or I
3+
- needle would move
- if the place where the alligator clip is attached, the reading would be different
paper clip
C
> 3
the terminals heat up a little
Our conclusion was
All metals conduct electricity, but maybe some non-metals can conduct electricity too.
