We usually wear special glasses and gloves in the chemistry labs. (safe) is the most important! Theoutfit(装备) prevents us from harmful chemical materials.
Our chemistry teacher always gives us the instruction sheet the night before the lab class to let us know a lot the experiments. During the class, she first goes over the steps of the experiments and then (divide) us into groups to do the experiments.
Doing experiments is really (interest). Once we tried to burn chemicals.
chemicals produced many colors offlames(火焰), including bright orange and dark green. "Wow!
beautiful it is!" we screamed.
After (finish) an experiment, we need to write a report. It consists of the steps, our feelings and the final results.
