Kia ora readers for today's blog I'm going to share what we've been doing in science for past few weeks. So we did the Metallurgy the materials that you need is the magnesium and held over the top of blue flame and it made a bright light but your not allowed to look because your eyes will be damage.
Magnesium
Magnesium is a silver-white metal that ignites easily in air and burns with bright light. Magnesium is one-third less dense than aluminium. Magnesium is easy to melt when it melting it's making a bright lights that your not allowed to look but once you take them off the fire it turns to powder but you really have to put them at the top of blue flame. And also the powder is hard to take off.
Glowing Splint
The glowing splint is making fire in the boiling tube. And the materials for that is the splint and when the splint has a fire it's called lit and it blew it out called glowing. And we put Hydrogen peroxide and manganese dioxide, producing oxygen. The glowing splint test is a test for an oxidising gas, such as oxygen. In this test, a splint is lit, allowed to burn for a few seconds, then blown out by mouth or by shaking. Whilst the ember at the tip is still glowing hot, the splint is introduced to the gas sample that has been trapped in a vessel.
