1. Study Hall: Sharpen your pencils…. Find your seat…… Work on something quietly at your desk…

2. Warm Up – 12/5/2013 We 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?

3. 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!

4. Announcements Tuesday, December 10 th, 2013: FINAL SCIENCE FAIR PROJECT IDEA AND HYPOTHESIS ARE DUE TO ME! Field Trip to Discovery Place, Monday Dec 9 th ! We are still in need of volunteers…..

5. Announcements 1 st Block MAP Testing TODAY READING You will stay in 1 st block for all of 1 st and 2 nd blocks, 3 rd and 4 th 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

6. Friday, December 6 th on: Thermal Insulators Thermal Conductors Electric Insulators Electric Conductors

7. 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 Activity This will be worth 300 points!!!! (informal notebook grade)

8. 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?

9. 3 rd and 4 th Blocks….. We are going to test a variety of objects using a conductivity meter today.

10. What is in a Conductivity Meter? An energy source: Battery An indicator: The red light A conductive material: 2 metal prongs

11. Let’s test some materials…. Copy this chart in your notebook: Object Hypothesis (Conductor/Insulator) Result (Conductor/Insulator )

12. Copy these objects into your table… IN THE OBJECTS COLUMN: METAL FORK PLASTIC FORK CAP ERASER TEXTBOOK LEGS ON A STUDENT CHAIR THE SEAT OF A STUDENT CHAIR SALT WATER PAPER CLIP ERASER EXPO MARKER TRAY ON MY WHITEBOARD

13. 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)

14. 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

15. Video Conductors and Insulators - YouTube

16. Discovery Ed “Walking on Coals” video and questions activity

17. 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.
