Unit 5, Activity 7, Finding Daylight Blackline Masters, Advanced Math-Pre-Calculus Page Comprehensive Curriculum, Revised 2008 172 Instructions How much daylight do we have each day? If you are reading this during the winter you would say that sunset comes awfully early. However, if it’s May where you live ,you will have noticed that it stays light well into the evening. This activity will have you explore daylight hours for various locations throughout the United States.
