Study Hall:

Sharpen your pencils….Find your seat……

Work on something quietly at your desk…

Warm Up – 12/5/2013We plug in the lamp, the light turns on…. • 1. How does this happen?• 2. What materials are used in the lamp’s

cord?• 3. How do you know?

Volunteers?

• The wires are metal (an electrical conductor)• The wires are covered with a plastic coating

(an electrical insulator)• This allows us to touch the cord while the

lamp is on!

Announcements

• Tuesday, December 10th, 2013: FINAL SCIENCE FAIR PROJECT IDEA AND HYPOTHESIS ARE DUE TO ME!

• Field Trip to Discovery Place, Monday Dec 9th!• We are still in need of volunteers…..

Announcements

• 1st Block MAP Testing TODAY READING• You will stay in 1st block for all of 1st and 2nd

blocks, 3rd and 4th blocks normal schedule– This will allow everyone enough time to finish the

test in 1 day– When you finish, work on your science homework

assignments and begin to study for your QUIZ

Friday, December 6th on:

• Thermal Insulators • Thermal Conductors • Electric Insulators • Electric Conductors

Notebook Check on Friday!

• I will be checking for the following:• 1. Notes• 2. Foldable• 3. Conductors and Insulators Worksheet

(front and back)• 4. Cut and Sort ActivityThis will be worth 300 points!!!! (informal notebook grade)

Progress Reports Given Out Today!

• Your progress reports should not be a surprise; you should be checking Powerschool

• If you received a grade lower than you expected, ask your self:

• Have I turned in all my homework?• Do I take good notes and keep an organized

notebook?• How have I done on my weekly quizzes?

3rd and 4th Blocks…..

• We are going to test a variety of objects using a conductivity meter today.

What is in a Conductivity Meter?

• An energy source:• Battery• An indicator:• The red light• A conductive material:• 2 metal prongs

Let’s test some materials….• Copy this chart in your notebook:

Object Hypothesis (Conductor/Insulator)

Result (Conductor/Insulator)

Copy these objects into your table…IN THE OBJECTS COLUMN:

METAL FORKPLASTIC FORKCAP ERASERTEXTBOOK

LEGS ON A STUDENT CHAIRTHE SEAT OF A STUDENT CHAIR

SALT WATERPAPER CLIP

ERASEREXPO MARKER

TRAY ON MY WHITEBOARD

Now fill in your hypothesis….

• If you think the object will conduct the energy from the battery, write conductor

• If you think the object will not conduct the energy from the battery, write insulator

• Go through each object listed, and complete your hypothesis (prediction; educated guess)

Let’s Experiment!

• I will pull a number from my bag• If I call your seat number, you will come up

and test the object from our list• If we see a red light = conductor• If we do not see a red light = insulator

Video

• Conductors and Insulators - YouTube

Discovery Ed

• “Walking on Coals” video and questions activity

Questions for the Video• What type of energy was this video discussing?

• Define this type of energy.

• How do daredevils walk across hot coals without getting burned?

• Write three examples not included in this video and explain why they are not good conductors.
