As an exchange student, I studied in France for two years.
My chemistry teacher Mrs. Louise usually gave us the instruction paper the night before the lab class and let us read it. During the class, she first went over the steps and then put us into groups of two to do the experiments(实验). What was special was that for every lab class, Mrs. Louise changed everyone's lab partner to make them work with different classmates.
We once tried to burn the chemicals and watch the colors of the flames (火焰). Different chemicals produced different colors, including bright orange and dark green. Many students in my class were surprised. Then they excitedly took pictures, posted them online and sent them to their friends. Mrs. Louise never got angry with us at all for our "noises".
After finishing an experiment, we had to write a lab report. If we had a big mistake in the experiment, we needed to know why it happened and what we should do to avoid it next time. The lab reports made up around 25% of our term grade.
