Presentation Transcript

  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 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…..

  5. Announcements • 1stBlock 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

  6. Friday, December 6th 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. 3rd and 4th 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:

  12. Copy these objects into your table…

  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.
