Hello. Some of the students in the highest level class are taking college courses this semester. One of the courses we are offering this year is Astronomy. In the astronomy class, the students sometimes have labs. That means that they do experiments and other hands-on activities. Here are some pictures from some of the labs they have had. These labs were all related to light.
The students are taking part in a spectroscopy lab. Students look at gas tubes. The gas is excited, and they determine what the gas is by looking at the spectrum through a spectroscope. This one is mercury.
