The increased remote observing capabilities of astronomical observatories allow their use in higher education. This is important for general high level education of science students as well as for early training of a future generation of radio astronomers. With the goal of introducing a group of undergraduate students currently enrolled in the Astronomical Laboratory course at NMT (PHYS-328L) to 1. the field of massive star formation, and 2. the techniques of professional radio astronomy, we propose observations of six star forming regions with the Arecibo telescope. We will observe simultaneously a tracer of molecular gas (H2CO 6cm absorption), and a tracer of ionized gas (H110a). The students will be able to plan, conduct, and analyze radio observations. They will verify the close relationship between massive star forming regions and molecular clouds, and determine kinematic distances to HII regions and molecular clouds based on the (LSR) velocity centroids of the radio recombination lines and the H2CO 6cm detections. The proposed pro ject is well understood due to previous work of the PI in this area, and we plan to observe during a period of the day when the telescope is not heavily used.
