Oct. 16 – Charging by Induction and Activities

Today we got a chance to try to charge different materials and see what happens.

Handout: Investigating Charges

This activity should prepare you for the lab tomorrow which will involve charging different materials.  I hope that through today's activities you got a sense of how difficult it is to charge objects and how much care you need to take to ensure that your experiments work well.

You also got your Chemistry Unit Test back.  Please let me know if you have any concerns with your mark!

I then talked about induction and how it works.  here are some brief notes:

Induction

Learning Goals: Understand how to charge without contact.

Success Criterial: You can complete the laboratory investigation tomorrow.

Induction is charging an object without contact.

Temporary:

 - A charged object is brought near a neutral object.

 - Charges separate in the neutral object.

Permanent:

 - A charged object is brought near a neutral object.

 - Charges separate in the neutral object.

 - Ground the neutral object.

 - Disconnect the object from the ground.
