This week in science we continued using the bunsen burners. We did an experiment with heating wood in the test tube. The experiment was set up so that there were two test tubes connected with an elbow joint. There was a second elbow joint coming out of the the test tube and one of the test tubes was in a cup of water. The other test tube had wooden splints in it. That test tube was being held by the arm of the long pole coming out of a base. The bunsen burner was under that test tube. When the bunsen burner was lit, the wood started turning darker and darker until it was black. There was a lot of smoke looking gas coming off the wood. The gas went through the elbow joints, some going into the other test tube and some going into the air. Condensation began forming again the sides of the test tube turned black like in the sugar experiment last week.

In both experiments the objects broke down. They both got darker and turned black eventually. They both got condensation to form on the sides. Both gave off a smell but there were some differences. The sugar melted but the wood didn't.

This week in science we used bunsen burners. The experiment we performed was to fill a test tube with sugar and place it over the bunsen burner. When we turned the bunsen burner on, eventually the sugar began melting. At first the sugar turned yellow and then it started getting to be brown. The sugar began turning into a liquid.The liquid's bubbles rose to the top of the test tube and smoke began coming off of it. The smoke caused condensation and rose into the air where we couldn't see it. Eventually the sugar turned black and hard. We broke open the test tube to observe the sugar closely. We learned that the sugar was broken down into it's elements.
