Week 24: New Unit 6 and the evidence of Charges

WEEK 24

In this Past week,  Our ChemTeam has started a new project to Possibly explain how certain things, such as a match, can be "pushed" or "pulled"  without a physical push or pull, which we hypothesised would be static electricity, or the  attraction  and repulsion of negative and positive charges. Using Tape, ALuminum Foil , paper and a glass rod, we did find that there was some wort of attraction and repulsion we couldn't see with a naked eye.


We  discussed if there  really were 2 different types of particles at all or if there was merely a diffiency of one partice that was transfered. The concention of this duscussion was to  test which process was actually happening. We later found out that at the subatomic level, little electrons, which are negatively charged particles, attract  electrons and repel protons. We also discovered the glass rod we were using was negatively charged so we could then easily  decide if an object was negatively or positively charged.
