From Hommocks Earth Science Department. As we (in the northern hemisphere) continue on to the darkest seasons of the year, it’s interesting to consider how the angle of the sun has changed from the first day of summer. There are a few interesting videos on sun angles we’ll post in the next couple of days. Hope you like them! (They’re great whether you’re in school or an adult looking out the window and thinking about the changes you observe in your own backyard!
