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.
