IF you are a HOME SCHOOLER or other parent seeking high quality instructional materials for your children Circle of Illumination Science Education has the perfect item: A hands-on workbook on seasonality!

Although a lot of attention has been given historically to the changes that occur over the year in day length a second factor is just as important: changes in the height of the sun over the horizon at mid-day. This is referred to as “sun angle”. Many people are surprised to learn that sun angle can vary in the Upper Midwest between winter and summer by as much as about 47 degrees!

With the use of this workbook students will learn how to calculate sun angle at noon on any given day of the year and then track how it changes over the course of an entire year. This new knowledge will not only help them understand this important factor behind our own seasonality but it can then be used to calculate sun angle at other places on Earth to provide insights into world climates.

In addition students will have an opportunity to do nature journalling, i.e., record observations and questions about daily weather.

PRICE: $25 plus taxes and shipping.

THIS IS A NEW PRODUCT UNDER DEVELOPMENT THAT WILL BE AVAILABLE BY EARLY NOVEMBER. THE OPPORTUNITY TO PLACE A PRE-ORDER WILL BE IN THIS SITE’s STORE PAGE SOON!
