The Chemistry department at the University of Waterloo is doing another collaborative periodic table project! If you missed out on participating in our 2011 Periodic Table Project, this is your opportunity to have your students celebrate and be part of a worldwide initiative.

STAO has Oxygen
The Science Teachers’ Association of Ontario has the oxygen tile. Contact Karen_Dodds@stao.org with any questions. Schools can hand in their completed tiles to the STAO Curriculum Coordinator Michael Franfort at michael_frankfort@stao.org.
The STAO deadline is Friday, February 22, 2019. This will give STAO one week to decide which tile to submit on behalf of Ontario teachers. You can find out more at the STAO conference playground or Chem 13 News exhibit booth at the annual STAO conference this November.
A candle and beaker of pink phenolphthalein solution are placed inside a jar. The candle is lit and the jar is capped. The flame expectedly goes out as the oxygen is depleted. After the flame is extinguished, the pink solution slowly fades to colourless. What has happened inside the jar?
