Videomicroscopy of Live Earthworms

提案编号：III-9361277 PI: Mary Appelhof机构：Flowerfield Enterprises标题：活体蚯蚓的视频显微技术本项目将采用视频显微技术，并使用类似于医学内窥镜的光纤来研究蚯蚓。该设备可以直接观察蚯蚓的消化道，泵送成对的心脏，它们的洞穴内部以及蠕虫从茧中出来的情况。这是可能的，因为幼虫是半透明的。学生们使用新设备所看到的录像也将成为可能。教师和学生对现有录像带的评价将用于确定要建造的设备的最佳排列。

Proposal Number: III-9361277 PI: Mary Appelhof Institution: Flowerfield Enterprises Title: Videomicroscopy of Live Earthworms This project will adapt videomicroscopy and use of fiber optics similiar to those used for endoscopy in medicine to study eartrhworms. The equipment will allow direct observation of earthworm digestive tracts, pumping pairs of hearts, the inside of their burrows and the emergence of the worms from their cocoons. This will be possible because young worms are quite translucent. A videotape record of what the students see using the new equipment will also be possible. Teacher and student evaluations of existing videotape will be used to determine the optimum array of equipment to be built.
