3-D Model of the Big Dipper
Rating

Students see firsthand that stars and constellations are not arranged in a flat, 2-D pattern in this Moveable Museum unit. The five-page PDF guide includes suggested general background readings for educators, activity notes, step-by-step directions, and a Big Dipper map. Students make their own 3-D models of the Big Dipper using readily available materials and examine their models, observing the 3-D constellation from new perspectives.

Ancient Lives
Rating

For classics scholars, the vast number of damaged and fragmentary texts from the waste dumps of Greco-Roman Egypt has resulted in a difficult and time-consuming endeavor, with each manuscript requiring a character-by-character transcription. Words are gradually identified based on the transcribed characters and the manuscripts' linguistic characteristics. Both the discovery of new literary texts and the identification of known ones are then based on this analysis in relation to the established canon of extant Greek literature and its lexicons. Documentary texts, letters, receipts, and private accounts, are similarly assessed and identified through key terms and names. Furthermore, an immense number of detached fragments still linger, waiting to be joined with others to form a once intact text of ancient thought, both known and unknown. The data not only continues to reevaluate and assess the literature and knowledge of ancient Greece, but also illuminates the lives and culture of the multi-ethnic society of Greco-Roman Egypt.

This is a project I assign my students in an introductory, non-science major astronomy class. Each student is assigned one of the 25 brightest stars in the sky and they are asked to research and apply concepts they have been learning in the class to their particular star. I leave it up to them to decide the format of their final project - most do PowerPoint but some have done videos or podcasts. One student actually landed a part time job at a radio station after they heard her recording her star project! Many students tell me this is a highlight of the course!
