This activity is used in conjunction with the STAR CHART OF THE NORTHERN SKY, a student made star chart that is available for purchase from Michael F. Ryan. In this activity, students are asked to spin the star wheel so that May 15th lines up with 8 p.m. Ursa Major (The Big Dipper) is high in the sky on that date. Students are then asked to focus their attention on the star in the bend of the handle of the Big Dipper. There are actually two stars close together. Students are then challenged to take their star chart out at night and see if they can split this star into two by using peripheral vision.
