Science 9 – Static electricity : what have i learned

3 most important things I’ve learned:

  1. A nucleus is made out of two particles called protons which are positive and neutrons which are negative.  I think this is important because it’s always good to know the basics of electricity so that you can use it in the future to help with labs, conclusions etc.
  2. An object that has negative charges repels from an object that contains negative charges if touched.  An object that has negative charges will attract to an object that has positive charges.  it’s important to know what charges attract or repel because you might question why an object attracts to another object so you will need this info to help.
  3. Induction is when you do not touch an object to charge a negative object and conduction is when you charge a neutral object by touching it to a charged object.  this is important because I always thought why a magnet moved when another magnet got close to it.  Now that I know this, I can always say that it’s induction.  therefore, it’s a useful life tool.

I found that the most helpful lab was the one online on Phet.  I found that the way they explained negative and positive charges helped me a lot to understand how the charges attract and travel through objects.  I also found it helpful because I’m a more of a visual learner so it was much easier to understand.
