Old Maps, Expeditions and Explorations: USERKAF’S SUN TEMPLE AT ABU SIR. Abu Sir has been called the site of the forgotten kings of the 5th Dynasty. One can see only 3 pyramids from a distance; those of Sahure -- Nyuserre -- Neferirkare. Abusir is about half way between Giza and Saqqara. Located here is another large royal cemetery of the Old Kingdom composed of four pyramids belonging to kings of the 5th Dynasty and the surrounding tombs built by royal family and officials. Additionally the kings of the 5th Dynasty constructed Sun Temples on the desert to the northwest of the pyramids.

Corkboard Connections: Hands-on Water Cycle Fun! Now that I'm retired, I often miss working with children; children are my inspiration and the classroom is my laboratory! Recently I accepted a position at a local school to work with kids during their year round intersession program, and I had the pleasure of teaching science to 5th graders for 3 days. I had a wonderful time teaching them about the water cycle and weather, especially since I was able to incorporate a hands-on activity and an exciting demonstration into our lessons. One activity was adapted from a terrific idea shared with me by Pat Calfee, a former elementary teacher who is now an educational consultant. When Pat was teaching 2nd grade, she used plastic rotisserie chicken containers to have her students create mini water cycles. Because 5th graders need to know the full water cycle including transpiration and run-off, we modified our mini water cycles slightly.
