Kia Ora,
Today I am sharing with you my experience today from using a Bunsen Burner. Today me Malama and Canada got into a group. I had the task of holding the test tube over the flame. When it got bubbly I poured it into the water. Here is some of the rules and more.
Aim: To demonstrate how to heat a liquid inside a test tube.
Equipment: Bunsen Burner, Heatproof mat, lighter, test tube, test tongs and safety glasses.
Method:
1. Light the Bunsen Burner.
2. Fill your test tube to approximately 5.ml water.
3. Turn the collar at the Bunsen Burner so it is a blue flame.
4. Holding the test tube with test tongs, tilt the test tube on a 4 degree angle and not place bottom of the test tube into the flames. Be sure that the mouth of the test tube is not pointing towards people.
5. Gently wave the test tube in and out of the flame. Remember you are trying to heat the liquid gently.
6. Once the water starts to bubble gently, take it away from the flame. Carefully pour the hot water in the sink.
