Abstract
This plant growth frame was designed for use in second and fourth grade classrooms as a part of National Science Foundation Grant TEI 8751303, Materials and Assistance for Science Teaching (MAST). We needed frames that were relatively inexpensive, could be made from locally available materials and would be easy to store when not in use. The frame is made from PVC pipe. The light source is a 48-inch, two-bulb shop light, using ordinary fluorescent tubes. A plug-in timer is used to control the time of illumination. Our first models included a plywood base, but some teachers have omitted this. The materials cost of each frame, including timer, shop light and bulbs, is about $35.
