Thurs., June 23, 2016 – Electricity Workshop

This blog post is working progress – please be sure to check back later, too 🙂


We participated in an excellent “Scientist in Schools” hands on workshop today. The activities complemented our work in electricity so far 

  • we have built circuits with SnapCircuits from HWDSB Kit services; we have drawn our own “crude” circuit diagrams
  • we have leaned about atoms & the flow of electrons/electricity
  • we have experimented with balloons and static electricity
  • We have learned about hydroelectricity (eg generating station downriver from Niagara Falls or river with dam, metal turbines (rotate around huge magnet), electrons flow and are directed through wires/power lines leaving the generating station)

Detecting electrons

Static electricity

Laser printers and photocopiers use static electricity (followed by heat) to apply ink/toner to paper!! Can you explain this to your parents??

BATTERIES: Making electricity with a chemical reaction

  • 3 kinds of metal
  • Electrolyte (fluid) – we will use salt water as our electrolyte 

Build a voltaic pile:

  • Bottom: metal (aluminum)
  • Middle: cardboard square soaked with electrolyte (salt water)
  • Top: metal (copper — a penny that is older than 1993)

We will measure the resulting electric charge with a volt meter 

Usin an aluminum tin &salt to power a dollar store calculator!

Gorgeous day for DPA in the morning! 

Families will have an opportunity to bid on a silent auction tomorrow after the Grade 6 Ceremony tomorrow! Students have been working hard on our art auction piece, a one of a kind upcycled, original, Rousseau School solid wooden teacher chair.

A picture of the finished chair will be posted here at the end of the day! GOOD LUCK, BIDDERS!
