How to do Nature Study


I am trying to add some Charlotte Mason’s methods in our homeschooling. I have been searching about Nature Study through the internet but I still feel a little lost. Many people use handbooks, follow plans or focus on specific topics for a while. Other use pre-printed notebooks. I would like to know how homeschoolers do it.

What supplies do I need to buy?
How long does it take?
What to put in a nature journal?
And any other suggestions you have for getting started.

My kids are going 4th, 7th, and 8th grades.

Thanks for reading!
