Have you heard of the Khan Academy?  It is a website where you can learn about hundreds of different topics at your open pace without being nagged to donate or follow advertising links. If you have children in school, these modules will keep them learning over the summer break and perhaps give them an advantage in their next grade. 
Students can learn early math by grade, from arithmetic to calculus, or follow a pathway of education in areas such as:

• Science and Engineering
• Computing
• Arts and Humanities
• Economics and Finance

If you'd like a deeper understanding of the biology which sustains our forests, try the Biology learning module at the Academy. It starts with the "scientific method" and proceeds from there. 
Have fun learning at the Kahn Academy!

The volunteers at the Morrell Nature Sanctuary have produced a richly illustrated Guidebook. It is now available and can be purchased for $10 from the main office at the Sanctuary. Proceeds will go to support the wonderful life and learning opportunities which this forest and lake provide to the public. ​
