Here's a clip from the 1970s that shows students working in a lab for a chemistry course at the University of California, Berkeley. Below are most of the shots found on the clip. 

A periodic table hangs from one of the lab's walls. 

A graduate student, who is wearing a white shirt with a red collar and red sleeve-ends, is helping students with their paperwork.

A young Asian woman is measuring a chemical or chemicals in a vial and looking carefully at the chemical or chemicals, perhaps looking for a chemical reaction like movement or a change of color. The same woman uses a beaker to pour a substance into a vial.

A young woman wearing a red top and blue jeans is writing in her notebook while seated. 

Two Asian students work with chemicals at a work bench.

A wide shot of the lab shows a bunch of stools along the work bench, the students, and all the equipment on the work bench. In the background, a bright and hazy white light comes through the lab's wide windows.
