This hands-on Groundhog Day science lab helps 4th and 5th grade students explore light and shadows through an engaging, standards-aligned investigation using a flashlight and a groundhog cutout. Students investigate how distance from a light source affects shadow size, measure shadows in centimeters, record data, analyze patterns, and write evidence-based conclusions. This activity blends seasonal fun with rigorous science content—making it perfect for January and February science units whil
