What’s Going On?
When a magnet is moved by a coil of wires, you can induce an electric current. This is the principle behind how most of the electricity is produced in the world; it’s just a question of where you get the energy to move the magnets. Every time a magnet passes the coil, a small amount of electricity is created, which makes the LED lights briefly flash on. Continue reading
Color Mixing Gobstoppers (Candy Science)
Gobstopper candies are known for their colors, but what would happen if they were dissolved in water?
Hard candies are known for their bright colors, delicious tastes, as well as having a ton of sugar. While munching on a handful of candy every once in a while can be a tasty treat, we like conducting experiments with them, too! We especially love Gobstoppers. They have layers of colors that, when they dissolve into water, do something very peculiar…

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 email@example.com.
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?

Have you ever noticed that warning about raw or undercooked seafood at the bottom of restaurant menus? Ever wondered why it’s there? Because fish carry a ton of parasites, and if they aren’t prepared correctly then those parasites can make it into your body. But it turns out, this fishy intersection with the wild world of parasites can teach us a lot about how these moochers help keep ecosystems healthy, and why we should protect them. Continue reading
