DESCRIPTION:Speakers: Krystal Marie  Ytang (Cebu Technological University 
 )\nUnderstanding Earth's rotation and the Sun's apparent daily motion is f
 undamental to astronomy education\, yet these concepts are often difficult
  for learners to visualize through textbook-based instruction alone. This 
 study developed and evaluated a Shadow Compass Learning Kit\, a low-cost i
 nstructional resource designed to support direct observation of changing s
 hadow positions throughout the day. The kit consists of a compass-aligned 
 baseboard with a vertical gnomon that enables systematic tracking of shado
 w orientation under natural sunlight. Field observations were conducted at
  Cebu Technological University – Main Campus\, Cebu City\, Philippines\,
  with measurements recorded at two-hour intervals from morning to late aft
 ernoon. Shadow positions were documented through tracings\, photographs\, 
 and observation logs to examine temporal changes in orientation. Results r
 evealed a consistent progression of shadow positions corresponding to the 
 changing position of the Sun in the sky. Shadows shifted from the northwes
 t during the morning toward the east in the late afternoon\, with the grea
 test directional change occurring around midday. Although minor variations
  in measured angles were observed\, the overall pattern remained stable ac
 ross observation periods\, providing clear observational evidence of Earth
 's rotation. The findings demonstrate that the Shadow Compass Learning Kit
  can effectively transform an abstract astronomical concept into an observ
 able phenomenon. Constructed from inexpensive and locally available materi
 als\, the kit offers a practical approach for supporting inquiry-based lea
 rning\, promoting scientific literacy\, and expanding access to astronomy 
 education in diverse learning environments. The study highlights the poten
 tial of simple observational tools to strengthen astronomy communication a
 nd foster meaningful engagement with fundamental Earth–Sun relationships
